  • Publication number: 20240391852
    Abstract: To enable highly efficient production of an olefin with a low environmental impact. The production includes a thermal cracking step of thermal cracking plastic to obtain a thermally cracked gas (G1) and a catalytic cracking step of cracking the thermally cracked gas (G1) in the presence of a catalyst to obtain a catalytically cracked gas (G2). When a ratio of an olefin to paraffin in the thermally cracked gas (G1) is indicated as R1 and a ratio of an olefin to paraffin in the catalytically cracked gas (G2) is indicated as R2, the following formula is satisfied: R2/R1 ?1.

  • Publication number: 20230113926
    Abstract: To provide a method for producing olefins having the carbon atom number of 2 to 3 with a high yield. A method for producing olefins including following steps (1) and (2): step (1): heating a polyolefin plastic to obtain a decomposed product (pyrolysis step); and step (2): causing the decomposed product obtained at the step (1) to contact with an MFI zeolite containing sodium atoms in the range of 0.10% by mass to 0.30% by mass to obtain catalytically cracked products containing olefins (catalytic cracking step).
