Patent number: 10610856Abstract: A catalyst for catalytic cracking of a hydrocarbon oil can produce a gasoline fraction having a high octane number in high yield while suppressing an increase in yield of a heavy distillate, and produce LPG having a high propylene content in high yield. The catalyst includes a specific amount of a granulated catalyst A that includes a zeolite having a sodalite cage structure, silicon derived from a silica sol, phosphorus and aluminum derived from mono aluminum phosphate, a clay mineral, and a rare-earth metal, and a specific amount of a granulated catalyst B that includes a pentasil-type zeolite, the ratio of the mass of phosphorus and aluminum derived from mono aluminum phosphate included in the granulated catalyst A to the mass of the pentasil-type zeolite included in the granulated catalyst B being 0.015 to 3000.Type: GrantFiled: October 8, 2013Date of Patent: April 7, 2020Assignee: COSMO OIL CO., LTD.Inventors: Yuji Saka, Tetsuya Kimura, Norihito Chiyoda, Kenji Nagai, Mitsunori Tabata
