Abstract
Ever more rigorous requirements for the quality of motor fuels are directed additionally towards the reduction of gasoline sulphur content. It is certain that this trends will also have a significant impact on the quality of fuels to be produced by domestic refineries throughout this decade.
Since the products obtained via fluid catalytic cracking are the main components of motor fuels, the removal of sulphur from process products is of extreme priority, and it is provided by feedstock hydrocracking as the most effective method.
The aim of this study is to analyse the influence of FCC feedstock pretreatment on yields and composition of products, as well as the sulphur quantity in liquid cracking products. Feedstock pretreatment was performed in laboratory hydrotreatment process testing equipment, and catalytic cracking on the MAT-system.
The results of experimental testing show that hydrotreatment of FCC feedstock has an influence on increasing of cracking gasoline and lowering the yield of cyclic oil and coke, sulphur content in liquid cracking products and increase of isoparaffin in cracking gasoline compounds.
