Аннотация:The pathways for the conversion of model compounds (acetone, n-hexane, hexene-1, cyclohexane, benzene) in pure form and acetone-hydrocarbon binary mixtures on Y and ZSM-5 zeolites are investigated. The conditions of the experiments simulate the catalytic cracking of bio-oil in a mixture with conventional feed. For the n-hexane-acetone model mixture, a significant effect of acetone addition on hydrocarbon transformation is observed, including the suppression of propane formation and an increase in the selectivity for C3-C4 olefins. In addition to enhanced olefins formation, the in situ FTIR spectroscopy results indicate a change in the reaction pathways of the acetone conversion in a hydrocarbon medium that also depends on the zeolite type (Y or ZSM-5). A reaction scheme is proposed, taking into account the change in the composition of the primary products of hydrocarbon cracking upon the introduction of a ketone.
