Abstract

The invention discloses a catalyst for waste and old plastic oil refining and a preparation method thereof. The catalyst comprises components of potassium carbonate, magnesium carbonate, hydrazine hydrate, molybdenum carbide, molybdenum oxide, cobalt oxide, platinum oxide, palladium oxide and nickel oxide, wherein the components are solids. According to molecular structures of polyethylene, polypropylene and polystyrene, through utilization of a principle that polyolefin macromolecules reduce petroleum micromolecules and reference of various national technical indexes of gasoline and diesel, the catalyst realizes that an oil product obtained by the catalyst has low sulfur content and high quality.

Description

technical field [0001] The invention relates to the field of industrial chemical industry, in particular to a catalyst for oil refining of waste plastics. Background technique [0002] At present, in the oil refining process of waste plastics, a certain amount of catalyst needs to be added to refine oil products. But with the difference of the catalyst composition, the quality of the obtained oil is also different. At present, the oil products refined by catalysts commonly used in the market have the following disadvantages: [0003] 1. Due to no stirring and mixing or insufficient catalytic reaction, cracking and catalysis cannot be carried out simultaneously, the conversion selectivity is not strong, there are a large amount of unsaturated hydrocarbons in the oil, and the oil label is limited, resulting in difficult oil quality. In line with national standards; [0004] 2. The sulfur content in the oil is relatively high, resulting in large sulfide pollution after using...
