    中国石油天然气股份有限公司委内瑞拉超重油减黏基础研究(供氢热裂化)项目(W2008E-1502/2) (供氢热裂化)项目(W2008E-1502/2)

    中央高校基本科研业务费专项资金资助(12CX06041A)。 (12CX06041A)

摘要: 采用高压釜研究了委内瑞拉常压渣油的常规减黏裂化与供氢热转化过程。结果表明,相比常规减黏裂化而言,供氢热转化过程中的供氢剂能够抑制气体产物、沥青质以及焦的形成,后者的气体收率比前者低0.5%~1.2%,生焦率低0.02%~0.98%,残渣油沥青质含量低0.6%~1.3%;在反应温度425℃、反应时间5~20 min条件下,供氢热转化过程的总降黏率、净降黏率变化分别为46.1%~54.8%、10.2%~33.0%;供氢热转化过程的较佳反应条件为425℃、5 min,此条件下供氢热转化生成油斑点实验等级为一级(ASTM D4740),运动黏度(50℃)为185.5 mm2/s,净降黏率为26.4%,满足了船运的基本要求。
