Abstract: A process for producing a purified synthesis gas stream from a feed synthesis gas stream comprising besides the main constituents carbon monoxide and hydrogen also hydrogen sulphide, HCN and/or COS, the process comprising the steps of: (a) removing HCN and/or COS by contacting the feed synthesis gas stream with a catalyst in a HCN/COS reactor in the presence of steam/water, to obtain a synthesis gas stream depleted in HCN and/or in COS; (b) converting hydrogen sulphide in the synthesis gas stream depleted in HCN and/or in COS to elemental sulphur, by contacting the synthesis gas stream with an aqueous reactant solution containing solubilized Fe(III) chelate of an organic acid, at a temperature below the melting point of sulphur, and at a sufficient solution to gas ratio and conditions effective to convert H2S to sulphur and inhibit sulphur deposition, to obtain a synthesis gas stream depleted in hydrogen sulphide; (c) removing carbon dioxide from the synthesis gas stream depleted in hydrogen sulphide, to obta

Abstract: Process to prepare a diluted hydrogen gas mixture starting from a gas mixture comprising hydrogen and carbon monoxide by (i) converting part of the carbon monoxide in said gas mixture to hydrogen and carbon dioxide by means of a catalysed water gas shift reaction to obtain a shifted gas and (ii) separating hydrogen from said shifted gas by means of a membrane to obtain the hydrogen comprising gas at the permeate side of the membrane and a carbon dioxide comprising gas at the retentate side of the membrane, wherein at the permeate side of the membrane a sweep gas is provided; (iii) cooling the carbon dioxide comprising gas to obtain liquid carbon dioxide and a gas mixture of non-condensable gasses and (iv) separating the liquid carbon dioxide from the non-condensable gasses; wherein the non-condensable gasses are fed into the hydrogen comprising gas.

Abstract: The invention is directed to a process to prepare a hydrogen rich gas mixture from a solid sulphur- and halogen-containing carbonaceous feedstock. The process involves the following steps. Step (a): gasification of the solid carbonaceous feedstock with an oxygen-containing gas to obtain a gas mixture comprising halogen compounds, sulphur compounds, hydrogen and at least 50 vol. % carbon monoxide, on a dry basis. Step (b): contacting the gas mixture with a quench gas or quench liquid to reduce the temperature of the gas mixture to below 900° C. Step (c) contacting the gas mixture with water having a temperature of between 150 and 250° C. to obtain a gas mixture comprising between 50 and 1000 ppm halogen and having a steam to carbon monoxide molar ratio of between 0.2:1 and 0.9:1.
