摘要:
流化催化裂化(FCC)油浆外甩量通常超过5%,需要脱固处理得到澄清油再利用。本文分析得出了向延迟焦化、溶剂脱沥青、减压蒸馏、加氢等重质油加工装置直接掺炼,局限性较大;利用减压蒸馏、溶剂抽提、超临界流体萃取等工艺,对澄清油“掐头去尾”,分离组分可生产针状焦、环保橡胶填充油、沥青树脂以及碳素纤维等高附加值产品。油浆组分通过延迟焦化制备针状焦,是工业化应用主体方向,但国内产品质量与国外尚有很大差距;油浆制备环保橡胶填充油,在降低环保橡胶油多环芳烃(PCA)和8种危害性稠环芳烃(PAHs)分别至3%和10mg/kg以下的同时,必须提高芳碳率(CA)值至10%以上来保持橡胶相容性,其收率及生产成本是工业化应用推广的制约因素。
