TO STUDY THE EFFECT OF COMPOUNDED RAW MATERIALS ON THE PERFORMANCE OF CATALYTIC CRACKING IN THE FLUIDIZED BED OF THE CATALYST

The article discusses the influence of compounded raw materials on the performance of the catalytic cracking process.The chemical composition of raw materials significantly affects the yield and quality of the resulting catalytic cracking products.Therefore, there is an urgent question of conducting extensive research, which can significantly expand the range of raw materials through the use of heavy oil residues, such as fuel oil, by mixing them with traditional catalytic cracking raw materials.However, as the raw materials become heavier, the content of sulfur-containing, nitrogen-containing and organic oxygen compounds, resins, metals and other substances that worsen the performance of catalytic cracking increases.In this regard, the preparation of raw materials is one of the main issues in intensifying the catalytic cracking process.In order to intensify the catalytic cracking process, we prepared a raw material mixture consisting of direct distillation fuel oil in a volume of 70% by weight. and non-hydrotreated vacuum gas oil in a volume of 30%, obtained by vacuum distillation of fuel oil from mixtures of oils from the Buzachinskoye, Akyubinskoye and Kumkol fields.In the course of the studies, it was found that the introduction of up to 30% vacuum gas oil into the fuel oil helps to reduce coke formation on the catalyst and increase the yield of the target gasoline product, and also reduces the amount of harmful emissions into the environment.
