H2S removal from syngas using wastes pyrolysis chars

Pyrolysis chars from wastes were investigated as sorbents for H2S removal from syngas. The H2S removal tests were performed at ambient temperature in various dry gas matrices (N2, Air, Syngas) to study the effect of the gas composition on the adsorption efficiency. Two chars were produced by the pyrolysis of: used wood pallets (UWP), and a 50/50% mixture of food waste (FW) and coagulation-flocculation sludge (CFS). The chars were functionalized...
