摘要

生物质醇解产生的重油降低了生物油品质。为此,本文考察了V-W-Mo-Cu 催化剂作用下重油的 加氢精制。结果表明,在330 ℃以上该催化剂才表现出加氢反应活性,在450 ℃时轻油产率最高可到93 %。延长加氢反应时间有利于重油低温下的聚合反应和高温下的裂解反应;同时,只有在6 MPa以上的初始氢压下才能饱和裂解片段,从而提高重油加氢所得的轻油产率。轻油的气相色谱-质谱联用仪(GCMS)分析结果表明,催化加氢使重油大分子裂解生成1-甲基-2-乙基苯、丁基苯、1-乙基-3-乙烯基苯和苯酚等小分子的芳烃和酚类物质。然而,加氢后催化剂的红外分析结果表明,重油同时发生了聚合反应,生成含有多种含氧官能团的大分子芳烃或酚类聚合物。经过550 ℃焙烧后,催化剂重复使用5 次,轻油产率仍有70 %。
