Abstract
The results of the study of the process of catalytic cracking of fuel oil on a microspherical zeolite-containing catalyst showed that the cracking of a mixture consisting of hydrotreated vacuum gas oil (85% by weight) and sulfurous fuel oil (15% by weight) leads to an increase in the yield of catalytic distillate by 5.4 – 7.7% by weight, for a mass feed rate of 2 and 4 hours 1, respectively. At the same time, there is a change in the output of all distillate components compared to their output from pure vacuum gas oil. A decrease in coke deposition on the catalyst by 1.9 – 2.6% by weight and an improvement in the quality of the products obtained were found. The content of sulfur and unsaturated hydrocarbons in gasoline obtained from hydrotreated raw materials is less, aromatic compounds are more. Light and heavy gas oils also contain significantly less sulfur. These studies will deepen the oil refining process, increase the yield of catalytic distillate and reduce the environmental burden.
