Patent number: 10131850Abstract: A naphtha and methanol mixed catalytic cracking reaction process involves a simultaneous cracking reaction of naphtha and methanol using a circulating fluidized-bed reactor comprising a reactor, a stripper, and a regenerator. The naphtha is supplied from the bottom part of the reactor at a position between 0%˜5% of the total length of the reactor, and the methanol is supplied from the bottom part of the reactor at a position between 10%˜80% of the total length of the reactor. The catalytic cracking reaction process uses the circulating fluidized-bed reactor and can crack naphtha and methanol simultaneously by having different introduction positions for the naphtha and methanol in the reactor, which is advantageous for heat neutralization, so that energy consumption can be minimized and also the yield of light olefins can be improved by suppressing the production of light saturated hydrocarbons such as methane, ethane and propane.Type: GrantFiled: July 30, 2015Date of Patent: November 20, 2018Assignee: Korea Research Institute of Chemical TechnologyInventors: Na Young Kang, Yong Ki Park, Won Choon Choi, Dae Jin Kim, Hwi Min Seo, Sunyoung Park, Joo Hyeong Oh, Sin Cheol Kang
