摘　　要：在实验室将废聚乙烯塑料、减压渣油以及它们的混合物 ,在反应温度 45 5～ 495℃、氢气压力 0 .1～ 4.0MPa和反应时间 2～ 8h的临氢条件下进行延迟焦化反应。结果表明 ,由于废聚乙烯焦化的液体产物组成主要为链烷烃和链α 烯烃 ,占 10 %的废聚乙烯塑料和减压渣油混合原料的延迟焦化加工过程 ,可以得到性质较好的焦化柴油馏分。废聚乙烯塑料的加入 ,还可以减少焦化炉管的生焦 ,延长装置的运转周期 。Delayed coking tests of waste polyethylene plastics, Shengli vacuum residue and their mixture of were conducted on a coking unit in the laboratory. The coking conditions were under a hydrogen pressure of 0.1-4.0 Mpa, a reaction temperature range of 455-495 ℃ and a reaction time of 2-8 h. Since the liquid product of the waste polyethylene plastics mainly consisted of alkanes and α alkenes, better quality gas oil could be obtained from processing the vacuum residue blended with 10% waste polyethylene plastics in comparison with processing vacuum residue alone. The co processing could also reduce the coking in the furnace tubes and prolong the running cycle. The said method is expected to be a waste plastics processing route for reducing environmental pollution.
