| description | An apparatus and method is presented for removing acid gases and other trace contaminants to very low levels in combustible gases generated from thermal gasification of biomass or refuse-derived fuels. The invention includes optimization of geometric variables, temperature and pressure set points via use of a pressurized bubbling fluidized bed reactor to convert granular raw (non-activated) sorbents and auto-generated biochar sorbents) into activated, highly dispersed, and ideally sized particles for removing acid gases and toxic metals. The system can incorporate a generated gas cooler, a gas-sorbent contact chamber or zone, and a novel filter (with or without additional gas cooling and residence time stages). |
