The Effect of Oxygen-containing Additives in Feedstock on the Performance of the Catalytic Cracking Process

Abstract

In this study, we found that adding catalytic cracking feedstock, vacuum gas oil, and naphthenic acids in the amount of 0.005–0.0075% vol. increased the liquid target fractions, i.e., gasoline and light gas oil. The decrease in the yield of hydrocarbon gas at a practically constant degree of conversion of the raw material indicated a small proportion of the reactions of re-cracking of the resulting products. This also indicated the resource-saving nature of the process, allowing a larger amount of gasoline fraction and light gas oil to be obtained, as well as, reducing the amount of coke formed on the catalyst at a constant volume of processed feedstock.
