PRODUCTION METHOD FOR CHEMICAL PRODUCTS AND CARBIDES

WIPO Patent Application WO/2023/145544

A1

This production method for chemical products and carbides comprises: a pyrolysis step for causing pyrolysis of a pulverized product of waste tires, to obtain a first gas fraction, a pyrolysis oil, and a residual fraction; a carbide recovery step for recovering carbides from the residual fraction; a hydrogenolysis step for causing hydrogenolysis of a raw material oil containing at least a portion of the pyrolysis oil, to obtain a second gas fraction, a light fraction, and a heavy fraction: and a steam-cracking step for causing steam cracking of a steam-cracking raw material oil containing at least a portion of the light fraction, to obtain a raw material for producing chemical products and carbides. The pyrolysis temperature for causing pyrolysis is 350-750°C. The raw material oil in the hydrogenolysis step contains a low-boiling-point raw material and a high-boiling-point raw material. The contained amount of the high-boiling-point raw material is at least 15 mass% of the total amount of the raw material oil.
