This invention discloses a catalyst composition, a method for preparing zeaxanthin ester, and the zeaxanthin ester itself. The catalyst composition, comprising an alkaline catalyst and a carbonyl iron catalyst, is used to isomerize lutein ester into zeaxanthin ester. Under alkaline conditions, the catalyst composition of this invention allows the carbonyl iron catalyst to complex with the double bond electron cloud of the 4', 5' carbon atom on the terminal benzene ring of the lutein ester molecule, significantly reducing the energy required for the terminal carbon to capture protons. This facilitates the migration of protons from one negative carbon ion site (6' carbon atom) to another site (4' carbon atom), accelerating the transfer of the double bond position. This reduces the activation energy, decreases the amount of alkaline catalyst required, shortens the reaction time, lowers the reaction temperature, and improves the conversion rate and yield of lutein ester.

The application provides a waste plastic hydrogenation catalytic cracking oil refining method and application. The catalyst carrier is ZSM-5 molecular sieve, and the active center loaded is a transition metal; in a hydrogen atmosphere, a high-temperature static cracking process of plastic and catalyst mixing. The reaction of polyethylene on the catalyst loaded with transition metal follows the carbon ion theory and the free radical catalytic pyrolysis. The ZSM-5 molecular sieve provides protons for the reaction, the protons are combined with polyethylene and then short chain olefins are generated through the carbon ion theory.

The method can relatively safely and environmentally protect convert the plastic into crude oil, the reaction temperature is low, and the catalyst effect is remarkable.
