加点“料”，老工艺焕新（唠“科”）

Core Insights - The F-T synthesis process, a nearly century-old technology, converts syngas (a mixture of carbon monoxide and hydrogen) into valuable chemical products like liquid fuels and olefins, remaining a backbone in the global energy and chemical sectors [1] - A recent breakthrough involves adding a trace amount of halogenated methane (e.g., bromomethane) to significantly reduce CO2 emissions during the F-T synthesis process, achieving a drop in CO2 generation from 30% to less than 1% with just 20 ppm of bromomethane [2][3] - This innovative approach not only enhances efficiency but also transforms carbon resource utilization, indicating a promising direction for the future of green chemistry [3] Industry Implications - The new method addresses the longstanding challenge of high carbon emissions in the F-T synthesis process, aligning with China's dual carbon goals and providing a pathway for the green transformation of carbon resources like coal, natural gas, and biomass [2] - The principle behind this technology involves the halogen atom acting as a protective layer on the catalyst surface, effectively preventing unwanted side reactions and guiding the reaction towards desired products [3] - This strategy of using minimal additives to control the microenvironment of catalysts could be applicable to other reaction systems, representing a significant advancement in chemical engineering and a potential key direction for future green chemical processes [3]
