Catalytic cracking process for biofeeds

Abstract

A process of catalytically cracking a feedstock based on a biocomponent contacts the feedstock with a catalytic cracking catalyst comprising a basic metal oxide on a porous oxide support at an elevated cracking temperature to eliminate oxygen from the biocomponent to form cracked hydrocarbon residues. The basic metal oxide of the cracking catalyst is preferably a metal oxide of Group 2 of the Periodic Table (IUPAC) such as calcium or magnesium on a support comprised of a non-acidic form of alumina such as gibbsite or boehmite. Preferred feedstocks are those based on triglycerides, especially vegetable oils, animal fats and algae oils.

AI Technical Summary

Benefits of technology

The present inventors discovered that certain types of base catalyst can help produce more desired products from feedstock like crude oil or gasoline by causing it to break down easier than traditional methods. This results in better yields compared to previous techniques used alone. Additionally, they also find other ways to make these fuels even stronger without adding too much weight on their owners' fuel consumption levels.

Problems solved by technology

The technical problem addressed in this patent text is the need for a more efficient and cost-effective method of converting biomass, such as vegetable oils and animal fats, into valuable liquid fuels and chemicals. Current methods of catalytic cracking using commercial FCC catalysts are not optimal for this purpose, resulting in low yields and product distributions. The patent text proposes a new method for catalytic cracking of biofeeds that can provide higher yields and product distributions.
