Estimating the term…
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).
A method for controlling trace contaminants in biomass and waste generated gases, said method comprising a pressurized bubbling fluid bed reactor and at least one sorbent material;
A method for controlling trace contaminants in biomass and waste generated gases comprising grinding and activating at least one sorbent material in a fluid bed reactor, adjusting velocity and pressure, allowing said gas and said activated sorbent to flow to at least one gas sorbent contact zone to provide contact time between said gas and said activated sorbent and thereafter to a filter zone where spent sorbent is removed from the decontaminated gas.
A method for controlling trace contaminants in biomass and waste generated gases, said method comprising activating a sorbent by grinding unactivated sorbent in a fluid bed reactor;
