Abstract: A process for treating a gas stream comprising H2S that includes the step of selectively oxidizing the H2S of the gas stream within a catalytic zone containing an oxidation catalyst and in the presence of an inert liquid medium and molecular oxygen to form elemental sulfur and a gas stream depleted of H2S. A liquid stream yielded from the catalytic zone and containing the inert liquid medium and liquid elemental sulfur undergoes a separation into a first liquid phase rich in the inert liquid medium and a second liquid phase rich in elemental sulfur. Either at least a part of the liquid stream or at least a part of the second liquid phase, or both, undergoes a combustion to form a fluid stream that comprises sulfur dioxide.

Abstract: A catalyst is provided comprising nickel in a reduced valence state on a carrier comprising zinc oxide and alumina, wherein the Zn:Ni atomic ratio is at least 12, and the catalyst particles are prepared by: mixing zinc oxide in the form of a powder and alumina or an alumina precursor in the form of a powder; peptising the powder mixture and forming an extrudable dough by adding acid and water to the powder mixture in such amounts that the dough contains 0.8-1.2 moles acid equivalents per kg powder; extruding the extrudable dough to form extrudates; drying and calcining the extrudates; impregnating the extrudates with an aqueous solution of a nickel compound; drying, calcining and reducing the impregnated extrudates. Further provided is a process for desulphurisation of a hydrocarbonaceous feedstock using such catalyst.
