Abstract: Title: MULTIPLE-STAGE CATALYST SYSTEM AND A PROCESS FOR PROPENE PRODUCTION (57) : Processes and multiple-stage catalyst systems are disclosed for producing propene by at least partially isomerizing butene in an isomer- ization reaction zone having an isomerization catalyst to form an isomer- 110 ization reaction product, at least partially metathesizing the isomerization 12 j-114 reaction product in a metathesis reaction zone having a metathesis catalyst to form a metathesis reaction product, and at least partially cracking the metathesis reaction product in a cracking reaction zone having a cracking catalyst. The isomerization catalyst may be MgO, and the metathesis cata- lyst may be a mesoporous silica catalyst support impregnated with a metal oxide. The metathesis reaction zone may be downstream of the isomeriza- tion reaction zone, and the cracking reaction zone may be downstream of the metathesis reaction zone. —124 120 2 130 -- NT 122-v 1302 130 - A_ 2 116 FIG. 1 W O 20 18/ 13657 6 Al (12) INTERNATIONAL APPLICATION PUBLISHED UNDER THE PATENT COOPERATION TREATY (PCT) (19) World Intellectual Property Organization International Bureau (43) International Publication Date 26 July 2018 (26.07.2018) WIPO I PCT (51) International Patent Classification: CO7C 6/04 (2006.01) CO7C 11/10 (2006.01) CO7C 11/06 (2006.01) CO7C 5/25 (2006.01) CO7C 4/06 (2006.01) (21) International Application Number: PCT/US2018/014131 (22) International Filing Date: 18 January 2018 (18.01.2018) (25) Filing Language: English (26) Publication Language: English (30) Priority Data: 62/448,476 20 January 2017 (20.01.2017) US (71) Applicant: SAUDI ARABIAN OIL COMPANY [SA/SA]; Post Office Box 5000, Dhahran, 31311 (SA).
