摘　　要：以废塑料和废机油为原料,共催化裂解制备燃料油,克服了废塑料裂解因传热差,裂解炉中温度极不均匀、结焦的难题,提高了燃料油得率。实验中考察了裂解温度、不同油固比、萃取剂对燃料油得率和组成的影响。在混合废塑料为PE∶PP∶PS=3∶1.2∶1、裂解温度为420℃、油固比为1.5、ZSM-5/50H分子筛为催化剂的条件下,燃料油得率可达到89%以上,汽、柴油比例达83%。采用络合萃取剂精制裂解产物可显著提高燃料油的安定性。Fuel oil is obtained by catalytic cracking of the waste plastic and waste lubricating oil,which overcomes the problems of poor heat transfer, extremely uneven temperature in pyrolysis furnace and coke and improve the yield of fuel oil. The effect of the temperature of catalytic cracking, the ratio of oil to solid and the extractant on the yield and ingredient of fuel oil,is investigated. When PE： PP： PS =3： 1.2：1 ,the ratio of oil to solid is 1.5 ,and the catalyst is ZSM- 5/50H molecular sieve,the yield of fuel oil can reach more than 89% and the ratio of gasoline and diesel is 83%. In addition, the stability of fuel oil can be significantly improved if the lysate is refined using complex extraction agent.
