Regenerable Sorbents for High‐Temperature Desulfurization of Syngas from Biomass Gasification
Single‐metal high‐temperature solid sorbents for syngas cleaning using Mn, Ca, Fe, Cu, or Mo supported on γ‐Al2O3 were synthesized, characterized, and tested in a fixed‐bed reactor. H2S and SO2 concentrations in the gas after treatment at T = 400 to 700 °C were compared with thermodynamic calculations. The Mn‐based sorbent showed the best ability to achieve a low sulfur residual in the gas, especially at temperatures above 600 °C. Sorbents with Fe, Cu, and Mo gave SO2 formation in the initial phase, but this could be avoided by a pre‐reduction treatment of the sorbent material.
