Nowadays processing of renewable biomass as an alternative to conventional oil feed draws much attention. The main drawback of such feed is high content of oxygenates which are difficult to refine by existing paths. A perspective approach could be their catalytic cracking as an additive to hydrocarbon conventional feed yielding additional quantities of C2-C4 olefins. The goal of this work is to research trends of hydrocarbon and model oxygen containing compound (acetone, glycerin) additives catalytic cracking in the presence of Y and ZSM-5 zeolite catalysts. In order to plan such experiments a central composite rotatable plan was designed. ZSM-5 content in the catalyst varied from 0 to 20 % (here and after %mass.) and composition of bio oxygenate additive to feed were chosen as independent variables. Oxygen containing feed additive consisted of acetone and glycerin binary mixtures, total content of oxygenates in the feed was fixed at 5 % in all experiments.
