Description

technical field

[0001] The invention belongs to the fields of oil refining, petrochemical industry and coal chemical industry, and relates to a method for lightening heavy oil / residue oil / coal tar, specifically, the process of converting heavy oil / residue oil / coal tar through catalytic cracking and polymerization The method of producing high value-added carbon microspheres and impregnating agent asphalt urgently needed in my country by an organic combination process method, and by-product gasoline and diesel oil at the same time. Background technique

[0002] Since Honda et al. discovered micron-scale mesophase carbon microspheres by separating pitch in 1973, carbon microspheres have been focused on by researchers due to their excellent performance and broad application prospects. Carbon microspheres are composed of graphite sheets distributed discontinuously in the graphite structure of the glass phase. Carbon microspheres have a structure of parallel stacking of layer molec...
