Abstract

The invention discloses a catalytic conversion method for preparing low carbon olefin and aromatic hydrocarbon from biological grease. A biological grease raw material contacts a catalyst containing modified beta zeolite in a composite reactor for a catalytic pyrolysis reaction, then a reaction product is separated from a spent catalyst, the separated spent catalyst is subject to steam stripping and coke-burning regeneration and then returns to the reactor for circulating use, and the separated reaction product is fractionized and separated to obtain target products, namely the low carbon olefin and the aromatic hydrocarbon. The method adopts the modified beta zeolite and zeolite with an MFI structure as the catalyst of necessary active compositions, and converts the biological grease into the low carbon olefin and the aromatic hydrocarbon in the same device in a high selectivity mode.

Description

technical field [0001] The present invention relates to a method for catalytic conversion of bio-oil, more specifically, relates to a method for producing low-carbon olefins and aromatics with high selectivity through catalytic conversion of bio-oil. Background technique [0002] The main component of bio-oil is triglyceride fatty acid lipid, which mainly contains carbon, hydrogen, and oxygen elements, and the content of sulfur and nitrogen is very small. It is a green and renewable resource, and with the application of transgenic technology, the output of bio-oil is rapid increase. Early studies mainly used bio-oils for thermal cracking to produce fuels, but the selectivity of target products was low. And by converting bio-oil into fuel through catalytic cracking method, the selectivity of the target product will be improved. [0003] US2006 / 0151357 A1 discloses a method for treating organic waste, which converts organic waste into fuel through multi-stage processing. Fi...
