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455~495℃、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,有望成为回收废塑料减少环境污染的一种途径。

Delayed coking tests of waste polyethylene plastics, Shenglivacuum 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 temperatur e 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, bet ter quality gas oil could be obtained from processing the vacuum residue blended with 10% waste polyethylene plastics in comparison with processing vacuum resid ue alone. The co-processing could also reduce the coking in the furnace tubes a nd prolong the running cycle. The said method is expected to be a waste plastics -processing route for reducing environmental pollution.
