Evaluating the Feasibility of Obtaining a Mesophase by Heat Treatment of Various Types of Hydrocarbon Raw Materials

Feasibility has been shown for obtaining anisotropic pitches by heat treatment of various types of petroleum raw materials such as isotropic pitches from heavy pyrolysis tar and heavy catalytic cracking gas oil. A dependence was found for the change in the group composition of the heat treatment res...

More Information
Summary:Feasibility has been shown for obtaining anisotropic pitches by heat treatment of various types of petroleum raw materials such as isotropic pitches from heavy pyrolysis tar and heavy catalytic cracking gas oil. A dependence was found for the change in the group composition of the heat treatment residues on the duration of the isothermal heating. A correlation was seen between the components insoluble in toluene and quinoline. Features of the optical texture of the heat treatment residues of various isotropic petroleum pitches were found.
