Scale-Up of the Ceramic Membrane Reactor for Continuous Biomass Gasification to Produce Clean Hydrogen-Rich Syngas

Membrane reactors could integrate biomass gasification, particulate matter (PM) removal, and tar-reforming in situ, offering a promising pathway to streamline the production of clean syngas from biomass. However, achieving continuous and stable biomass gasification within such reactors remains a significant challenge. In this study, we present a scalable packed-bed ceramic membrane reactor for continuous biomass gasification to produce clean hydrogen-rich syngas. Under optimized conditions (biomass feed rate of 6 g min –1 and steam feed rate of 1.5 mL min –1 ), the reactor achieved a stable H 2 /CO ratio of ∼1.4 and a syngas yield of ∼1.34 m 3 kg corncob –1 . Continuous 330 h operation maintained stable syngas composition, with periodic maintenance every 110 h to remove membrane carbon deposits. This study establishes a framework for developing durable packed-bed ceramic membrane reactors for efficient, continuous syngas production from biomass.
