Investigation of Mixed Property of Vacuum Residuum and Catalytic Cracking Decant Oil

Wang Yang-fei

Abstract

The properties of the mixed residuum were carefully investigated with the aid of modern analytical apparatus,when catalytical cracking decant oil was mixed with vacuum residuum;and some mathematical models of properties were built up.The research showed that average molecular weight and some atomic compositions of the mixed residuum may be plused;and the viscosity,residue carbon and group compositions of the mixed residuum were not plused.
