摘　　要：在小型固定流化床催化裂化装置上,选用常规重油裂化催化剂MLC-500,以典型催化裂化原料(加氢处理减压蜡油TC-M)为空白原料,对掺炼不同比例生物重油(BHO)的油品分别在不同掺炼比例和不同剂油比下进行了裂化反应性能的试验。试验结果表明,随着BHO掺炼比例的增加,裂化反应深度变弱、转化率降低。在产品选择性上,除液化气选择性略差,其它产品选择性均有一定改善。工艺条件考察结果表明,选择适中的剂油比,既可以保证适当的重油转化深度,同时又可兼顾产品的选择性。汽油烯烃质量分数增加约10百分点,芳烃含量降低,RON变化不明显。当剂油质量比为6.0时,掺炼15%BHO后转化为氧化物CO_2和CO的比例分别为14.9%和7.8%,其余计入水中大约占77.3%。液体产物(包括汽油、柴油和重油)中基本不含氧元素。The cracking reaction performance was investigated for a typical FCC feedstock（TC-M,a hydrotreated vacuum gas oil）and a feed blending different proportions of bio-heavy oil（BHO）using the conventional RFCC catalyst MLC-500 with various catalyst/oil ratio in a fixed fluidized bed.The results showed that the degree of cracking reaction is weakened and the conversion rate is decreased with the increase of the proportions of BHO.For the product selectivity,the product selectivities are improved except LPG.The process condition test indicated that the appropriate catalyst to oil ratio can ensure the proper depth of heavy oil conversion and better product selectivity.Gasoline olefins increase by about 10 percentage points,aromatics decreases,and no obvious RON changes.The oxides in BHO that converted to CO and CO2 are 14.9%and 7.8%,respectively when the mass ratio of catalyst to oil is 6.0 and BHO blending is 15%,the rest of oxides are counted in water.Liquid products（including gasoline,diesel and heavy oil）are essentially free of oxygen.
