【Abstract】 The composition and properties of residual oils as well as the effects of operating con- ditions on the rates and severity of visbreaking reactions were discussed. Such a discussion is referential to the proper selection of visbreaking operating conditions. On the basis of summarization of a large amount of experimental data obtained from the research on visbreaking reaction by RIPP in the past years. the authors have put forward such a view that for the domestic vacuum residua, the asphaltene content in feedstock is not a main factor effecting the maximum allowable conversion in visbreaking. The upflow-type visbreaking process, being considered as adaptable for domestic situarion, was recommended.更多还原
