Composition of the Products of Thermolysis of Heavy Oil with the Addition of Light Hydrocracked Naphtha

A series of experiments has been carried out on the thermolysis of heavy oil using 2.5-10.0% light hydrocarbon naphtha additive of vacuum gasoil prepared from conventional oil. It has been shown that the employment of the additive increases the conversion of heavy oil, avoids coke formation in the p...

Description
Summary:A series of experiments has been carried out on the thermolysis of heavy oil using 2.5-10.0% light hydrocarbon naphtha additive of vacuum gasoil prepared from conventional oil. It has been shown that the employment of the additive increases the conversion of heavy oil, avoids coke formation in the products of thermolysis as compared to the basic process without additive, and does not prevent the decrease in the viscosity of the products during thermolysis. It has been revealed on the example of the heavy oil of Ashal'chinskoe deposit (Russia) that the thermolysis with the addition of light naphtha gives a liquid product with the yield higher than 97% and the viscosity of less than 80 mm 2 /s.
