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 discloses a kind of furnace tube ash removal agent. It is constituted by the following components by weight fraction: 10-30 parts of composite inorganic salt, 10-30 parts of composite mineral aggregate, 5-10 parts of alkaline substance, 1-3 parts of catalyst, 3-8 parts of accelerator, 3-5 parts of corrosion inhibitor, 100-200 parts of water. The furnace tube ash removal agent of the application has the effect of removing hard ash, which forms a low-melting eutectic with the hard scale on the pipe wall, so that the hard ash becomes a loose and easily peeled product and falls off by itself; reduces carbon ion emission and improves combustion efficiency; while removing ash, a protective film is formed on the surface of the furnace tube, which also inhibits the deposition of ash; ash can be removed online without stopping production; eliminates dust pollution and its impact on the respiratory system, which is beneficial to environmental protection.

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. However, due to the too large molecule, the polyethylene cannot directly enter the inside of the ZSM-5 molecular sieve channel, so the molten polyethylene will first react under the catalysis of the active center on the surface, depolymerize into products with small molecular weight, then enter the channel to react, and after entering the inside of the channel, secondary reactions such as beta-scission, isomerization, aromatic ring formation and the like occur. 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.
