METHOD FOR PRODUCING CHEMICAL PRODUCT

WIPO Patent Application WO/2023/145545

A1

A method for producing a chemical product which comprises a pyrolysis step in which chopped waste including waste tires is pyrolyzed to obtain a first gaseous fraction, a pyrolysis oil, and a residue, a hydrocracking step in which a raw oil including at least some of the pyrolysis oil is hydrocracked to obtain a second gaseous fraction, a light fraction having boiling points not higher than 350°C, and a heavy fraction having boiling points exceeding 350°C, and a steam cracking step in which a steam-cracking raw oil including at least some of the light fraction is steam-cracked to obtain the chemical product. In the pyrolysis step, the proportion of the pyrolysis oil to the sum of the first gaseous fraction, pyrolysis oil, and residue is 45 mass% or higher. In the hydrocracking step, the raw oil comprises a low-boiling-point raw material having boiling points not higher than 350°C and a high-boiling-point raw material having boiling points exceeding 350°C, and the content of the high-boiling-point raw material is 15 mass% or higher with respect to the whole raw oil.
