Description
Technical Field
The invention relates to the field of petroleum processing, in particular to a method for producing light oil by a catalytic cracking raw material high-energy electronic cracking method.
Background
At present, catalytic cracking raw materials are subjected to heat exchange and heating by a heating furnace, then are sprayed into oil mist flow by an atomizing nozzle, and are mixed with a glowing regenerated catalyst carried by steam in a riser reactor, and the oil mist flow and the hot regenerated catalyst are separated in a cyclone separator after a cracking reaction. The oil gas enters a fractionating tower for distillation to obtain a target product, namely a light oil product. The heavy fraction is divided into two paths, one path returns to the raw material, the reaction is carried out, and the other path is discharged out of the device (generally called catalytic slurry oil). The catalyst (spent agent) enters a regenerator for burning, and the reaction by-product coke is removed for regeneration. Catalytic cracking typically produces about 4% dry gas, 7% to 10% coke. Due to the generation of dry gas and coke, the effective utilization rate of the catalytic cracking raw material is reduced. The catalytic cracking unit cyclone separator and the catalyst regeneration system have complicated equipment, high manufacturing cost and large capital occupation. The catalytic cracking process catalyst belongs to a consumable product, is a rare earth catalyst at present, and consumes non-renewable rare resources.
Disclosure of Invention
The invention aims to provide a method for producing light oil by a catalytic cracking raw material high-energy electronic cracking method, which aims to overcome the defects, reduce the yield of dry gas and coke, produce more light oil and improve the utilization efficiency of the catalytic cracking raw material.
a method for producing light oil by catalytic cracking raw material high-energy electronic cracking method comprises the following steps:
S1, heating the catalytic cracking raw material to the temperature of 350-400 ℃, and then mixing the catalytic cracking raw material with atomized medium gas, wherein the volume ratio of the catalytic cracking raw material to the atomized medium gas is 1:3, and the atomized medium gas is hydrogen or dry gas;
S2, spraying the mixed catalytic cracking raw material and atomized medium gas through an atomizing nozzle to form an oil gas mist flow, wherein the grain size of more than 90% of atomized oil drops in the oil gas mist flow needs to be less than 5 microns;
s3, the oil gas fog flow is touched with high-energy electrons generated by an electron accelerator to carry out cracking reaction to obtain a reaction product, and the reaction product is condensed and cooled to 40-60 ℃ to carry out gas-liquid separation: returning part of the separated gas to the step S1 to be continuously used as the atomized medium gas, and collecting, sampling and analyzing the other part of the gas; and collecting the separated liquid to obtain the light oil product.
The catalytic cracking raw material is one or a mixture of more of paraffin base crude oil vacuum heavy oil, furfural extract oil, ketone benzene wax oil, vacuum wax oil, normal pressure heavy oil and propane deasphalted oil.
The energy level of the electron accelerator is 2.5MeV, and the high-energy electron dose is 200KGy/kg oil.
The light oil products include gasoline and diesel oil.
The invention has the beneficial effects that:
1. High yield of light oil
High energy electrons collide with oil molecules in the reaction, and the collision positions are random. Because the energy carried by the high-energy electrons is far higher than the bond energy between oil molecule atoms, the oil molecules are broken at the collision position of the high-energy electrons to form small molecules, thereby achieving the purpose of cracking. Avoiding the selectivity of chain scission in thermal cracking. The generation of dry gas and coke is just caused by selective chain scission of thermal cracking, so that the generation of a large amount of dry gas and coke can be avoided, and light oil products are produced.
2. Energy saving
The reaction temperature of the catalytic cracking raw material in the process is about 350-400 ℃, which is far lower than the reaction temperature of coking and catalysis about 500 ℃.
3. Environment-friendly
the technology does not use water. The coking hydraulic decoking generates a large amount of oily sewage, and the steam for catalytic cracking is used for fluidizing and conveying the catalyst to generate a large amount of oily sewage.
