摘　　要：本文在连续进料流化床实验台上采用ZSM-5催化剂对生物质和废弃油脂单独催化热解以及共催化热解进行了实验研究。主要考察了反应温度和质量空速对废弃油脂催化热解以及不同有效氢碳比对生物质和废弃油脂共催化热解的影响。结果表明,在温度为550℃、质量空速为0.35h^(-1)时,总化学品(芳香烃+烯烃+C5化合物)碳产率达到最大值(53.9%)。生物质和废弃油脂共催化热解能够大幅提高烯烃和芳香烃的产率,在较高有效氢碳比下(>0.8),丙烯的选择性高达60%。Catalytic and co-catalytic pyrolysis of biomass and waste oil were conducted in a fluidized bed with ZSM-5 catalyst. The effects of reaction temperature, weight hourly space velocity （WHSV） and hydrogen to carbon effective （H/Ceff） ratio on the product distribution of waste oil pyrolysis and co-catalytic pyrolysis with biomass were studied. The results show that the maximum petrochemical （olefins, aromatics and C5 compounds） yield of 53.9% was attained at the temperature of 550℃ and WHSV of 0.35 h-1 for catalytic pyrolysis of waste oil. The co-catalytic pyrolysis of biomass and waste oil increased the olefin and aromatic yields dramatically. The propylene selectivity is higher than 60% when the H/Ceff ratio is higher than 0.8.
