【摘要】 以ZSM-5分子筛作为催化剂,以废食用油/废机油为原料,在实验室自制固定床催化裂化装置中进行催化裂化制备芳烃的研究,通过考察裂化温度、质量空速以及所用ZSM-5的硅铝比对催化裂化反应的影响,确定优化的反应条件。结果表明:最佳裂化温度为450℃、质量空速为0.4 h^-1,ZSM-5的硅铝比为25∶1,在此条件下液体产物的产率为49.11%,液体产物的酸值为0.5 mg（KOH）/g,皂化值为3.4 mg（KOH）/g,主产物芳烃产率为98.83%,其他化合物含量较低。说明硅铝比为25∶1的HZSM-5分子筛催化废食用油/废机油共裂化制备芳烃具有非常高的选择性,为废食用油/废机油共裂化制备芳烃实现提供了理论依据。更多还原

【Abstract】 Using ZSM-5 Zeolite as catalyst and waste cooking oil/waste lubricating oil as raw material, aromatics were prepared by catalytic cracking in laboratory fixed bed catalytic cracking unit, the effect of cracking temperature, mass space velocity and Si/Al ratio of ZSM-5 on catalytic cracking are investigated to determine the optimal reaction conditions. The results show that the optimum cracking temperature is 450 ℃, the mass-space velocity is 0. 4 h^-1, the Si/Al ratio of ZSM-5 is 25 ∶1,the yield of liquid product is 49. 11% and the acid value of liquid product is 0. 5 mg（KOH）/g, the saponification value is 3. 4mg（KOH）/g, the yield of main product is 98. 83%, the content of other compounds is low. The results show that HZSM-5Zeolite with a Si/Al ratio of 25 ∶1 has a very high selectivity in the co-cracking of waste cooking oil/waste lubricating oil to aromatics, which provides a theoretical basis for the co-cracking of waste cooking oil/waste lubricating oil to aromatics.更多还原
