摘要
在小型溶剂脱沥青试验装置上,向三种减压渣油掺兑催化裂化油浆后进行了丁烷馏分脱沥青的研究.油浆的加入对溶剂脱沥青过程有较大的影响.在相同的脱沥青工艺条件下,掺油浆后的渣油所得DAO收(?)加,DAO及脱油沥青的质量都明显改善.本文对掺油浆渣油脱沥青过程的机理及其在重油深度加工中的作用进行了讨论.
Investigations of butane deasphalting were carried out in a bench-scale unit for blending FCC slurry into three vacuum residua respectively. The addition of slurry has greater influence on solvent deasphalting. Under the same conditions, DAO yields of the residua blent with slurry increased, while quali-ties both DAOs and deoiled asphalts were improved evidently. The mechanism of deasphalting of the resi-due blent with slurry and its role in heavy oil upgrading were also discussed.
