Abstract
The routes of transformation of vegetable oils under catalytic cracking conditions have been investigated. The influence of the component composition of the catalyst on distribution of the desired cracking products and their chemical group composition has been revealed. It has been shown that introduction of H-ZSM-5 zeolite into the composition of the oil cracking catalyst promotes the formation of C2-C4 light olefins—the yield of propylene and butylene mainly increases. During cracking on bizeolites catalysts, high yields of both gasoline fractions and light olefins are observed. The relationship between the unsaturation index of the vegetable oils and the product distribution during their catalytic cracking has been established. Oils with a high index of unsaturation are cracked on the bizeolite catalyst yielding primarily mono- and polyaromatic hydrocarbons.
