A Y-zeolite-containing composite material with micro/mesoporous structure had been synthesized from kaolin by means of the in-situ crystallization method.The obtained samples were investigated by XRD and BET methods.Evaluation of catalytic activity of both the commercial Y-zeolite and the novel Y-zeolite-containing composite material was carried out in the pulse micro-chromatography platform with two probe molecules of different molecular sizes:VGO feedstock and 1,3,5 tri-isopropyl benzene.It was found that the Y-zeolite-containing composite material was richer in external surface and meso-/macro-pores;the Y-zeolite-containing composite material demonstrated a smaller rate of deactivation compared to the commercial Y-zeolite.

It was found that the Y-zeolite -containing composite material was richer in external surface and meso- / macro-pores; the Y-zeolite-containing composite material demonstrated a smaller rate of deactivation compared to the commercial Y-zeolite.
