Study on the Hydroconversion Law of Coal-Based Heavy Fractions with Different Catalyst Contents Based on an Improved Separation Method.

ABSTRACT: Heavy fractions (e.g., asphaltene and resin) can easily be subjected to physical aggregation and chemical coking reaction through molecular force in the process of lightweight processing and use of coal tar (CT), such that the normal processing and use can be affected. In this study, hydrogenation experiments were performed by regulating the catalyst to oil ratio (COR), while the heavy fractions of the hydrogenated products were extracted based on a novel separation method (e.g., the resin with a poor separation effect and rare existing research). The samples were analyzed through Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, nuclear magnetic resonance spectroscopy, and thermogravimetric analysis. On that basis, the composition and structure characteristics of
