Process using a TiO2-based composition for capturing halogen compounds contained in a synthesis gas

摘要

Use of a composition in upstream of a Fischer-Tropsch synthesis unit as a scavenger mass for removing halogenated impurities such as hydrogen fluoride, hydrochloric acid, hydrogen bromide and/or hydrogen iodide contained in a gaseous mixture and as a catalyst for hydrolyzing of carbonyl sulfide and/or hydrogen cyanide, where the composition comprises 30-99 wt.% of titanium oxide and 1-30 wt.% of at least a sulfate of an alkali-earth metal including calcium, barium, strontium or magnesium, is claimed.
