Abstract: An Y-zeolite-containing composite material(novel structure zeolite Y,NSY) with micro/mesoporous structure has been synthesized by industrial production. The industrial NSY have investigated by XRD, BET and SEM. Evaluation of catalytic activity of both the commercial Y-zeolite and the novel Y-zeolite-containing composite has carried out in the pulse micro-chromatography platform with probe molecule 1,3,5 tri-iso-propyl benzene. It is found that the Y-zeolite-containing composite is richer in external surface and meso-/macro-pore; The evaluation result of RU shows that catalyst NSC has good hydrothermal stability, selectivity to coke and heavy oil conversion ability than the commercial catalyst.
