CATALYST FOR DIRECT PRODUCTION OF LIGHT OLEFINS AND PREPARATION METHOD THEREOF

摘要

Disclosed herein is a novel F-T catalyst system suitable for the selective production of light olefins from syngas produced from natural gas (syngas to olefins; STO), which contains an iron-based catalyst and a calcium oxide (CaOx) prepared by a sol-gel process and shows an increased yield of C2-C4 light olefins and improved catalyst stability.
