    Abstract: The present invention is directed to a process for the removal of hydrogen sulfide and sulfur recovery from a H 2 S-containing gas stream by catalytic direct oxidation and Claus reaction through two or more serially connected catalytic reactors, wherein a specific control of the oxygen supplement is operated. The control and improvement of the process is obtained by complementing, in each major step of the process, the H 2 S-containing gas stream by a suitable flow of oxygen, namely before the H 2 S-containing gas stream enters the Claus furnace, in the first reactor of the process and in the last reactor of the process. Especially in application in a SubDewPoint sulfur recovery process the H 2 S/SO 2 ratio is kept constant also during switch-over of the reactors R1 and R by adding the last auxiliary oxygen containing gas directly upstream the last reactor R so that the H 2 S/SO 2 ratio can follow the signal of the ADA within a few seconds.

    Abstract: The invention is a process for removing sulfur from a gas containing sulfur compounds as H2S, SO2, COS, CS2..., in a quantity of up to 15%wt; it particularly concerns gases emanating from the Claus process. The process comprises a first hydrogenation of the sulfur compounds into H2S, the hydrogenation gas being used to regenerate a deactivated bed of oxidation catalyst, both being carried out at 200-500° C. After sulfur removal, the resulting gas undergoes a second hydrogenation step and then a direct oxidation step, said step being operated under the dew point of sulfur to trap the formed sulfur in the catalyst. In the further cycle, the gas streams are switched so as to regenerate the catalyst in run which is deactivated. In a preferred embodiment, the process operates in at least 2 identical reactors, each containing a bed of hydrogenation catalyst followed (in the sense of the flow of gas) by a direct oxidation catalyst bed containing an embedded heat exchanger.
