摘要：通过对比废弃塑料（PE）和渣油的热重曲线（TG／DTG），研究了两者的热解特性，论证了利用延迟焦化方法处理聚乙烯类废弃塑料的理论可行性；同时通过模拟延迟焦化实验，针对性地考察了废弃聚乙烯延迟焦化及废弃聚乙烯与渣油共延迟焦化的反应特性，采用模拟蒸馏方法分析了燃料油产物的成分组成，探讨了废弃聚乙烯延迟焦化方法制取燃料油的生产可行性。结果表明，PE的主要热解温区为350℃～480℃，渣油的为250℃～460℃，两者的热解特性有很大的相似性。PE热解的液体产物中汽油和柴油馏分达到62％，蜡油馏分为38％；PE热解的气相产物为小分子的烃类和氢气。PE与渣油共延迟焦化的液体产物中汽油馏分明显比渣油单独焦化的增加。
By comparing the thermogravimetric curves （TG/DTG） of waste polyethylene and residual oil, the theoretical feasibility of treating waste polyethylene by delayed coking was demonstrated. With the experiments of simulating delayed coking, the reaction characteristics of the simplex waste polyethylene and the waste polyethylene-residual oil mixtures were studied. The components of fuel oil from the products with simulated distillation were analyzed. The production feasibility of this technology was discussed. In addition, it proposed the industrial application model to achieve the delay coking disposal. The results show that the temperature zone for PE pyrolysis is 350 ℃ -480 ℃, and that of residue oil is 250℃ -460℃. The pyrolysis characteristic of both samples is very similar. The gasoline and diesel oil fraction in liquid product from PE pyrolysis is 62%. The wax oil accounts for 38%. The gas from PE pyrolysis is mainly hydrocarbon with small molecular amounts and hydrogen. The gasoline fraction increases remarkably from delayed co-coking of PE and residue oil than that from pyrolysis of residue oil solely.
