Developing a Quantitative Spatial Resolution of Deactivation Effects on FT Synthesis in a Microchannel Reactor When Operating with Ultra-Low Sulfur Levels

摘要

Fischer-Tropsch (FT) is receiving new attention for its ability to generate conventional fuel from stranded, or unconventional natural gas, and alternative renewable biomass sources. Being a catalytic process, the catalyst is subject to deactivation via multiple mechanisms [1-2]. Sulfur is the foremost among the poisons causing permanent catalyst deactivation. Despite the impact of 'S', the number of published quantitative investigations related to practical conditions is quite modest. While the recommendations for industrial syngas are typically <15 ppb S, [3-5] other publications would suggest unobservable impact at much higher exposures.
