Activities of HCeY vacuum gas-oil cracking catalysts based on the H-form of Fe-modified kaolinites from Kazakhstan deposits with and without zeolites are reported. The physicochemical properties of the catalysts were determined. The main cracking product of vacuum gas oil on Fe-modified H-kaolinites without zeolites was light gas oil, the yields of which was 65.3-67.3%. Adding zeolite increased the gasoline yield up to 22% with rather high feedstock conversion (up to 90.3%).
