Catalyst specially for preparing gasoline and diesel oil with waste plastics

Abstract

The catalyst specially for preparing gasoline and diesel oil with waste plastics consists of Pt, Re, aluminum hydride, nickel fluoride, nickel nitrate, alumina, silica, chromium oxide, chromium phosphate, magnesium carbonate, bentonite, No. 101 white acid pickling carrier, aluminum sulfate, sodium silicate and distilled water in certain weight proportion. Compared with available technology, the catalyst specially for preparing gasoline and diesel oil with waste plastics has the features of powerful reaction capacity, high activity, powerful antitoxication capacity, long service life, high heat stability, high steam stability, high mechanical strength, etc.

Description

1. Technical field [0001] The invention relates to a catalyst, which belongs to the field of chemical industry, in particular to a special catalyst for preparing gasoline and diesel from waste plastics with strong activity and high oil yield. 2. Background technology [0002] In recent years, the production of gasoline and diesel by catalyst cracking and reforming process is a new process, in which the quality and technology of the catalyst is the key to ensure the oil yield and oil quality. At present, the waste plastics produced by many domestic chemical companies are extracted Catalysts for oil, some can only produce C 1 -C 4 Hydrocarbon gas (also known as liquefied gas) or wax oil, some catalysts have a low oil yield, only about 30%, and the catalyst is easily poisoned and loses its activity, and loses its chemical reaction ability. Some catalysts are afraid of moisture and water vapor. It loses its activity and decomposes into a powdery mud. There are no air-permeable...

[0002] In recent years, the production of gasoline and diesel by catalyst cracking and reforming process is a new process, in which the quality and technology of the catalyst is the key to ensure the oil yield and oil quality. At present, the waste plastics produced by many domestic chemical companies are extracted Catalysts for oil, some can only produce C 1 -C 4 Hydrocarbon gas (also known as liquefied gas) or wax oil, some catalysts have a low oil yield, only about 30%, and the catalyst is easily poisoned and loses its activity, and loses its chemical reaction ability. Some catalysts are afraid of moisture and water vapor. It loses its activity and decomposes into a powdery mud. There are no air-permeable gaps. The gas hydrocarbon molecules lose their chemical reaction on the surface and through the gaps. At the same time, they cannot restore crude oil. Some catalysts are not resistant to high temperatures and have a short service life. , prone to aging
