Definitions
- the present invention relates to a process for converting hydrocarbons, for example a process for refining or petrochemicals, or else fine chemicals, in the presence of a catalyst used in a three-phase reactor and in which the number of liquid Peclet (Pel) is between 0 (excluded) and around 10.
- a catalyst used in a three-phase reactor and in which the number of liquid Peclet (Pel) is between 0 (excluded) and around 10.
- the present invention relates more particularly to chemical conversion processes which have a relatively high exothermicity or endothermicity, and which therefore require control of the reaction from the thermal point of view.
- the present invention applies more particularly to exothermic reactions occurring at high temperature, for example above 100 ° C. and most often above 130 ° C. generally under an absolute pressure greater than 0.1 megapascal (MPa) and often greater than 0.5 MPa.
- MPa megapascal
- the chemical conversion reactors used can be of several types, the solid being used either in a entrained bed, or in a bubble column reactor or slurry bubble column type depending on the name.
- Anglo-Saxon with contacting the gas with a very finely divided liquid / solid mixture, (or slurry according to the Anglo-Saxon name).
- the term slurry will be used in the remainder of this description to designate a suspension of solid particles in a liquid.
- the heat of reaction is usually removed by a cooling exchanger, generally internal to the reactor.
- the reactor used is preferably a bubble column.
- the bubble columns comprise a liquid medium containing in suspension solid particles generally mainly catalytic particles and comprise at least one means for introducing at least one gaseous phase comprising at least one reagent, via minus a distribution means which produces gas bubbles usually having a relatively small diameter. These gas bubbles rise in the column and at least one reagent is absorbed by the liquid and diffuses towards the solid.
- the solid is a catalyst
- the reactants are converted on contact into gaseous and / or liquid and / or solid products according to the conditions of the conversion and the type of catalyst.
- the gaseous products optionally comprising at least one unconverted gaseous reactant and the gaseous products possibly formed during the reaction are collected near the top of the column.
- the suspension, containing the liquid used to form the suspension of the solid and the liquid products formed during the conversion, is recovered by a line generally located at a level close to the upper level of the suspension in the column.
- the solid particles are then separated from the liquid by any means known to those skilled in the art, for example by filtration.
- any means known to those skilled in the art for example by filtration.
- reference will be made for example to the patent application of the applicant EP-A-820 806 cited in reference and the description of which must be considered to be included in the present description because of this citation. .
- the installations of the method according to the invention also generally comprise separation means, for the production on the one hand of a liquid fraction, on the other hand possibly of residual gaseous products or formed during the conversion, and possibly of inert.
- separation means for the production on the one hand of a liquid fraction, on the other hand possibly of residual gaseous products or formed during the conversion, and possibly of inert.
- the catalysts used in these processes, as well as the methods of making these catalysts are well known to those skilled in the art. These catalysts can be of various natures, and most often contain at least metal chosen from the metals of groups 5 to 1 1 of the new periodic classification of the elements (groups Ib, Vb, Vlb, Vllb, and VIII of the old classification periodic).
- the support is generally a porous material and often a porous inorganic refractory oxide.
- this support can be chosen from the group formed by alumina, silica, titanium oxide, zirconia, rare earths or mixtures of at least two of these porous mineral oxides.
- the desired products are generally substantially completely separated from the catalyst (for example up to residual catalyst levels of the order of 1 to a few parts per million (ppm), so that they can be used or treated in subsequent steps. .
- a quantity of solid particles of catalyst representing from 10 to 65% by weight of the slurry. These particles most often have an average diameter of between about 10 and about 800 microns. Finer particles may possibly be produced by attrition, that is to say by fragmentation of the initial catalyst particles.
- patent application EP-A-0 450 861 it has been described in patent application EP-A-0 450 861 the use of a catalyst based on cobalt dispersed on titanium oxide in a reactor of the bubble column type. Furthermore, patent EP-B-0 450 860 describes a method making it possible to operate this same type of reactor in an optimized manner.
- the performance of the catalyst depends essentially on the concentration of gaseous reactant (synthesis gas) in the reactor, that is to say of the partial pressure of carbon monoxide and hydrogen in the zone reaction.
- Peclet numbers for the gas phase greater than 10 lead to an operating mode of the type piston (plug flow) for the gas phase
- Peclet gas numbers (Pe g ) less than 1 correspond to systems in which the gas phase is perfectly agitated. Perfectly agitated systems correspond to zero Peclet gas numbers.
- the method for optimally conducting a bubble column which is described in patent EP-B-0 450 860 comprises the injection of gas at an average surface speed such that the formation of gas plug (slug flow) is avoided,
- the surface speed of the gas being greater than or equal to 0.2 (H / D ax )
- Another condition relates to the surface speed of the liquid and the speed of sedimentation of the solid (generally the catalyst) so that the solid is properly fluidized in the liquid phase.
- the invention relates to a process for converting hydrocarbons by reaction in the presence of a catalyst, implemented in a three-phase reactor and in which the number of liquid Peclet (Pe ; ) is between 0 (excluded) and around 10, preferably between approximately 0.005 and approximately 8, even more preferably between approximately 0.01 and approximately 5 and very preferably between approximately 0.02 and approximately 3 or even between approximately 0.03 and approximately 1.
- Pe liquid Peclet
- This process makes it possible to control the reaction on the thermal level and to favor the formation of the desired products.
- the invention relates to a process for converting hydrocarbons, in a reaction zone containing a suspension of solid particles in a liquid, which comprises solid particles of reaction catalyst. Said suspension is also called slurry.
- the process according to the invention is therefore implemented in a three-phase reactor.
- the method according to the invention will be implemented in a three-phase reactor of the bubble column type.
- the piston flow generates a significant temperature profile which makes thermal control difficult. Indeed, the mixture of reactants entering the reactor is subjected to the reaction and this continues as the fluid progresses in the column. In this type of reactor operation, the concentration and the partial pressure of the reactants decrease along the reactor while that of the products (gaseous or liquid) and of the water produced by the reaction increases.
- the piston flow is therefore at the origin of a concentration gradient associated, in the case of a strongly exothermic or strongly endothermic reaction, with a large temperature gradient along the reactor.
- reaction 2 When the parallel reaction for the formation of undesirable products C (reaction 2) has a greater activation energy (E2) than that (E1) of the main reaction for the formation of the desirable products B.
- E2 activation energy
- E1 activation energy of the main reaction for the formation of the desirable products B.
- the rate of formation of methane increases faster with the temperature than that of other hydrocarbons.
- the two reactions being exothermic (enthalpies ⁇ 1 and ⁇ H2 of negative reactions 1 and 2), the progress of the reaction causes an increase in the calories released by the reaction, which promotes the increase in temperature and therefore the formation unwanted products C.
- the present invention describes a process making it possible, by controlling the parameters associated with the reaction, to promote the formation of the desired products B, via reaction 1.
- H height of expansion of the catalytic t.
- Figure 1 shows the evolution of the temperature differential ( ⁇ T), that is to say of the temperature increase due to reactions 1 and 2, as a function of the liquid Peclet number (Pe / ).
- This temperature differential increases markedly for liquid Peclet numbers greater than a few units.
- FIG. 2 shows the evolution of the selectivity (S n ) in the desired product, as a function of the liquid Peclet number (Pe / ). As can be seen in this figure, the selectivity decreases more and more significantly when the number of liquid Peclet exceeds several units.
- the selectivity to desired products B decreases when the temperature differential in the reactor increases, and the number of liquid Peclet Pe / appears as a parameter for controlling the reaction.
- the lower limit of the Peclet number depends on the activity of the catalyst in a perfectly stirred reactor, therefore inter alia on its composition and / or on its method of preparation. As the Peclet number increases, the conversion also increases. However, it is preferable that the Peclet number is not too large so as not to have a temperature profile which makes thermal control difficult and which leads to too low a selectivity for the desired product, as shown in Figures 1 and 2.
- a high selectivity in desired products i.e. for example a selectivity higher than 50%, preferably higher than 60% by weight, more preferably higher than 70% by weight
- a sufficient conversion i.e. for example a conversion greater than 40%, preferably greater than 50%, more preferably greater than 70%
- the number of Peclet Pe / is therefore between 0 (excluded) and approximately 10, preferably between approximately 0.005 and approximately 8, even more preferably between approximately 0.01 and approximately 5 and very preferably between approximately 0.02 and approximately 3 or even between approximately 0.03 and approximately 1.
- liquid Peclet number When the liquid Peclet number is included in these ranges of values, a hydrocarbon conversion process is obtained which has optimized performance in terms of conversion and selectivity to desired products, as well as better control of the heat emitted. by the reaction, which also makes it possible to avoid a possible too rapid deactivation of the catalyst in the case of exothermic reactions.
- the method according to the invention will preferably be operated with a surface speed of the gas U g of less than 35 cm. s ' 1 , more preferably less than 30 crn.s "1 , in order to favor the transfer of the gas into the liquid phase and therefore the reaction, but also in order to avoid too strong attrition of the catalyst grains.
- FIGS. 3 and 4 represent the size distribution of the particles of a hydroprocessing catalyst based on cobalt and molybdenum dipersed on alumina before reaction (curves 1) and after 10 days of test in three-phase reactor (curves 2). This distribution is displayed in terms of% volume of particles for different values of the ratio of * Jd p avg (ratio between the diameter of the catalyst particles and the average diameter of all the particles).
- the hydrocarbon conversion process according to the invention can be implemented in any type of three-phase reactor, preferably in a bubble column or a bubble column type reactor. It seems advantageous to operate in reactors of sufficient size, in particular in order to obtain sufficiently high hourly productivity (weight of desired products formed in one hour). Thus, it seems preferable to preferably use one or more reactors having a diameter greater than approximately 2 meters, more preferably greater than 6 meters, or even greater than 7 meters, in the process according to the invention.
- the catalysts used in the process according to the invention contain at least one metal chosen from the metals of groups 5 to 1 1 of the new periodic classification (groups Vb, VIb, Vllb, VIII and Ib of the old classification ).
- the catalyst can contain at least one activating agent (also called promoter) chosen from the elements of groups 1 to 7 of the new periodic classification (groups la, 11a and IIIb to Vllb of the old periodic classification). These promoters can be used alone or in combination.
- activating agent also called promoter
- the catalyst can optionally be dispersed on a support, the support then preferably comprises an inorganic refractory oxide chosen from the group consisting of aluminas, silica, titanium oxide, zirconia, rare earths.
- the operating conditions of the hydrocarbon conversion reaction are generally well known.
- the optimal mode of operation of the reactor according to the invention is generally situated at a temperature between 160 and 450 ° C, preferably between 200 and 420 ° C, for a pressure between 0.1 and 20MPa, preferably between 0.5 and 10 MPa, very preferably between 1 and 8 MPa.
