Combined catalytic conversion method for biological oil and fat and mineral oil

Abstract

A method for catalytically transforming bio-oil and mineral oil combination comprises the following steps: contacting bio-oil and mineral oil with catalyst containing modified beta-zeolite in a compound reactor to carry out catalytic cracking reaction, separating the reaction resultant with the spent catalyst, processing the spent catalyst by stripping and burning and adding into the reactor for recycling, introducing the separated resultant from the reactor, and distilling to obtain target product low-carbon alkenes, gasoline, diesel and heavy oil. By adopting the catalyst containing modified beta-zeolite and zeolite with MFT structure as the necessary active component, the method can achieve higher yield of low-carbon alkenes, particularly propylene, wherein the total yield of C2 to C4 alkenes based on carbon balance is larger than 40wt percent, and the yield of propylene is above 21wt percent.

AI Technical Summary

Benefits of technology

This new combination catalysis technology described for converting biomass into liquid fuel has several benefits compared to traditional methods like gasoline production. It uses special types of molecular sieve called beta zeolenes (BZ) that have certain modifications made from their crystal lattice. These BzS's help increase its effectiveness at producing lower carbons such as ethylene while also improving energy efficiency when used alone. Overall this results in improved yields of desired products.

Problems solved by technology

This patented describes methods that convert plant or animal fats (or greases) into liquid transportation substances called biofucls. These liquids have specific properties like being able to absorb water vapor when heated up at different temperatures depending on their chemical composition. Additionally, these liquors may also include various compounds found naturally within them.
