Mixed support of Y zeolite and titania-silica composite oxide for the heavy oil hydrotreating catalyst
重质馏分油加氢处理催化剂用Y型分子筛—钛硅氧化物复合载体研究

Titania-silica composite oxides(CTS) were prepared by the sol-gel method combined with supercritical CO2 drying,and then CTS was mixed with HY zeolite by different methods to obtain the composite supports(Y/CTS).The structure and acidity of the supports were further modified by P.Hydrotreating catalysts were prepared with Y/CTS as supports and Ni-W as active metal through the equal volume impregnation method.The effects of the mixed method and the content of HY zeolite in Y/CTS on the catalyst behavior were...
