Abstract

Biomass gasification for syngas production is one of key operating units in the biomass utilization process, however its overall efficiency and stability are normally limited by the presence of complex impurities including particulate matters (PMs) and tars. Herein, a highly integrated ceramic membrane-based reactor was developed for high temperature syngas cleaning to allow the efficient in situ removal of PMs and tars from bio-vapours generated by biomass gasification. In specific, silicon carbide (SiC) membrane could in situ separate the PMs from biomass volatiles, while structured Ni 15La 5/S1-SiC catalyst (nickel and lanthanum-laden silicalite-1 zeolite supported on SiC foam) could promote the catalytic reforming of tars. Compared to other control reactors (i.e., with either membrane or catalyst alone), the integrated reactor demonstrated synergistic intensification in producing clean syngas from biomass gasification, with PM and tar removal efficiencies up to ~97% and ~90%, respectively, and excellent stability in five-cycle evaluations at 800 °C.
