A series of CO2 adsorption tests were conducted in a fluidized bed vessel using an impregnated polyamine sorbent. This sorbent was cross-linked using a silyl derivative to improve its stability and hydrophobicity. The fluidization and adsorption beha

A cold-flow circulating fluid bed (CFB) was operated using coke breeze with a packed-bed standpipe over a range of riser and standpipe air flows. The bed materials were selected to simulate solids flow in a CFB gasifier (carbonizer) but are generally
