    摘要: Provided is a method for producing chemical products and carbides, including: a pyrolysis step of obtaining a first gas fraction, a pyrolysis oil, and a residual fraction by pyrolysis of a crushed material of waste tires; a carbide recovery step of recovering a carbide from the residual fraction; a hydrogenolysis step of obtaining a second gas fraction, a light fraction, and a heavy fraction by hydrogenolysis of a raw material oil containing at least a part of the pyrolysis oil; and a steam-cracking step of obtaining a chemical product and a raw material for producing a carbide by steam cracking of a steam-cracking raw material oil containing at least a part of the light fraction, in which a pyrolysis temperature of the pyrolysis is 350 to 750°C, and in the hydrogenolysis step, the raw material oil contains a low-boiling-point raw material and a high-boiling-point raw material, and a content of the high-boiling-point raw material is 15% by mass or more on the basis of a total amount of the raw material oil.
