Abstract

The invention discloses a heavy oil / residual oil / coal tar catalytic cracking-polymerization reaction lightweight device and a method thereof, and belongs to the oil refining, petrochemical engineering, coal chemical industry field. According to the invention, the heavy oil / residual oil / coal tar is used for producing the high additional value carbon microsphere and impregnant asphalt in urgent demand through a technical method of organic combination of catalytic cracking and polymerization reaction; meanwhile, gasoline and diesel oil are byproduct; the lightweight oil product can be greatly produced, the technical flow is simplified, and the whole energy consumption is reduced.

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...
