摘要
Abstract
The distillation process of vacuum residue blended with coal tar was investigated in terms of of resource efficiency.The results indicated that the distillation yields of vacuum residue had been improved.At 550 ℃,more than 15% feedstock for catalytic cracking plant was obtained when blended with 20% coal tar compared to that from pure vacuum residue.And the yield of the distillates was increased by 5%.The softening point of residual oil was increased and colloidal system of vacuum residue was changed with the addition of coal tar,which made the distillation residue a more appropriate candidate for asphalt.The mechanism of intensifying distillation was also discussed based on the characteristics of petroleum system.关键词
