Abstract

The invention provides a novel process for utilizing catalytic cracked heavy oil, comprising the step of the synthesis of catalytic cracked heavy oil. The invention discloses a novel process for utilizing the catalytic cracked heavy oil of oil refineries, comprising the steps of: directly synthesizing condensed polynuclear anime by using the catalytic cracked heavy oil as a raw material, separating solid from liquid, refining solid resin, and returning feed oil, which is not involved in reaction, to a catalytic cracking device of a refinery to be used as a high-quality catalytic cracked raw material. The novel process has high utilization rate on the catalytic cracked heavy oil, is environmental-friendly and free of pollutant emission and can generate favorable economic and social benefits. The invention further provides the condensed polynuclear anime obtained with the novel process, and the condensed polynuclear anime has the advantages of good heat resistance, favorable self-lubricating property and favorable combinability with other materials, has the 10% thermal gravimetric temperature being above 380 DEG C and the final carbonization yield being above 50%, and can serve as C/C and C/plastic composite material matrices to be applied to various fields.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to a new process for utilizing catalytic cracking heavy oil and a condensed polynuclear aromatic resin prepared by the process. Background technique [0002] The heavy oil produced by the catalytic unit of the refinery contains a large amount of polycyclic aromatic hydrocarbons and colloidal asphaltenes that are difficult to crack again; and these heavy oils contain metal catalyst powder, such as alumina, which is difficult to remove. Although the content is very small, about 4ppm, it affects refining. Subsequent deep processing of heavy oil in the factory. At present, part of the FCC heavy oil is re-smelted, and the other part is used as a fuel oil blending component or as a raw material for the production of petroleum coke, and the added value is not high. In addition, through the extraction method, the polycyclic aromatic hydrocarbons in the catalytic cracking heavy oil are separated, a...
