Abstract

A method for processing heavy petroleum crude provides for preliminary modification of a part of the initial raw material and/or heavy petroleum crude which is different by its content from the initial raw material to be processed. For that purpose it is subjected to processing by air at a temperature of 200-300 °C at a mass ratio between the air and the raw material equalling 0.1-0.6:1, respectively, giving a gaseous phase which is removed and a liquid product which is then subjected to vacuum distillation with extraction of a distillate evaporating before the temperature of 540 °C. The distillate is mixed with the initial petroleum crude to be processed at the distillate content of 2.0-25.0 % by weight of the total of the obtained modified mixture. The modified mixture is subjected to cracking.

Well, for example, hardening the process of vacuuming the gas oil by blowing it off the catalytic converter does not allow the process to be carried out for 500-530 If presently, this method is available in the original raw materials, it is purely alkaline phenylated. 93/19139 ΡСΤ / ΙШ93 / 00067

- 2 - or block oxides of ethylene and προπylene (вυ, Α, Ι474Ι68). Use of this product through the use of this method makes it possible to increase the yield of bezyzin from 27.78% by weight to 28.92%, all of which are 5 available.

There are a number of means in which, in the case of catalytic dosing, there is a risk of cracking in the presence of oxygen. Po ;. One of the eggs ^χ heavy heavy raw materials is heated to a temperature of 450-550 ° C and mixed with air. Mixture of food-0 ut in a reactor with a completely foreign layer of aluminum catalyst. The kreking department has an additional increase due to the burning of part of the raw materials in the upper section of the processing unit.

If this process is essentially used, the air is used5 for the sole purpose of increasing the temperature in the process. Thanks to this, it is possible to increase the conversion, but most of the raw materials are consumed by burning. The method is beneficial only in the case of the use of low-cost catalysts ((з, Α. 2476729). 0 In the meantime, a small amount of raw material is consumed, and it is a matter of personal, vacuum gas that heats up to 200-300 ° C. The feedstock is supplied to the processing unit, which is also supplied by air in the amount of 1.3–4.0 wt. The processing of the products is in the area of the goal of catalyzing a catalyst at a temperature of 500-53 ° C. The air flow varies depending on the green target product (gasoline, light gas oil).

There is still another way of treating heavy oil-5 raw materials. It is convenient in that the source of raw materials, namely, hot gas, is heated to a temperature of 2 °-300 ° С and - ο - working on the road ^χ ο.ν: πρ and λ'assass.

The processing is subject to the standard conditions ^χ : temperature of 5Сϋ ° С, catalyzed-5-integer (al., З, 1754764).

When this method exists, the output of light products from 47.0 wt. (without using air) up to 61.0 wt. .

In order to ensure that the targeted products are delivered, the user will benefit from the best possible use of air. Otherwise, the method is suitable for reprocessing only such a convenient gas oil.
