Abstract

A catalyst for cracking the waste plastics to produce fuel oil (gasoline or diesel oil) may be the DeLaZSM-5 prepared by modifying zeolite molecular sieve ZSM-5 or the composite cracking catalyst containing at least two carried metallic oxides as active components. Its advantages are low cracking temp and high output rate and quality of fuel oil.

Description

1. Technical field

[0001] The invention belongs to the technical field of catalysts, in particular to a catalyst for cracking waste plastics to produce fuel oil. 2. Background technology

[0002] The disposal of waste plastics is not only the need of environmental protection, but also opens up an important way for the rational reuse of resources. At present, the treatment of waste plastics can be roughly divided into the following four methods: landfill method, incineration method, recycling method and chemical recycling method. Among them, the chemical recycling method uses light, heat, radiation, chemical reagents, etc. to degrade waste plastic polymers into monomers or oligomers. The degradation products are monomers that can be used to synthesize new polymers, and the degradation products are oligomers that can be used as oils, and the production process will not cause air pollution, so this technology is considered to be the most promising recycling method for waste pl...
