Abstract: This paper reviews the 60-year development of fluid catalytic cracking engineering technology at SINOPEC Guangzhou Engineering Co., Ltd., which has evolved alongside advancements in fluid catalytic cracking technology. The development of fluid catalytic cracking engineering technology can be chronologically divided into stages of initial foundation, technological breakthroughs, and large-scale plant. Through the efforts of generations of catalytic experts, a technology cluster has been established, featuring 11 reaction-regeneration configurations adaptable to diverse feedstocks and a comprehensive engineering innovation system. These achievements provide robust technical support for the expansion of fluid catalytic cracking engineering technology. The company has successfully developed the industrial-scale methanol to olefins (DMTO) complete technology, forming a world-leading DMTO engineering system. This breakthrough has accelerated the rapid emergence and growth of coal-to-olefins strategic industryin China, playing a vital role in advancing the oil substitution strategy and safeguarding energy securityof China.
