Patent number: 10844294Abstract: An integrated process catalytically cracks whole light crude oil into light olefins, especially propylene and ethylene. The process is integrated with an adjacent conventional fluid catalytic cracking unit whereby the heavy liquid product mixture (light and heavy cycle oils) from whole crude oil cracking is mixed with vacuum gas oil (VGO) for further processing. The process comprises recycling total product fraction of light cracked naphtha (LCN) and mixing with fresh crude oil feed. High propylene and ethylene yields are obtained by cracking the whole light crude oil and LCN in an FCC configuration using a mixture of FCC catalyst and ZSM-5 additive at a temperature between, that of conventional FCC and steam cracking.Type: GrantFiled: March 14, 2019Date of Patent: November 24, 2020Assignee: King Fahd University of Petroleum and MineralsInventors: Abdullah Mohammed Aitani, Sulaiman Saleh Al-Khattaf, Akram Abdulhakeem Al-Absi
