20120058921 | PROCESS FOR PRODUCING A PURIFIED SYNTHESIS GAS STREAM - 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 H | 03-08-2012 |

20120128579 | PROCESS TO PREPARE A HYDROGEN RICH GAS MIXTURE - 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. Step (d): subjecting the gas mixture obtained in step (c) to a water gas shift reaction wherein part or all of the carbon monoxide is converted with the steam to hydrogen and carbon dioxide in the presence of a catalyst as present in one fixed bed reactor or in a series of more than one fixed bed reactors and wherein the temperature of the gas mixture as it enters the reactor or reactors is between 190 and 230° C. Step (e): carbon dioxide and sulphur compounds are separated from the shifted gas mixture obtained in step (d) by contacting the shifted gas mixture with a solvent comprising dialkyl ethers of polyethylene glycol. | 05-24-2012 |
20130172432 | PROCESS FOR PREPARING A PARAFFIN PRODUCT - The invention is a process for preparing a paraffin product from a carbonaceous feedstock comprising (a) partial oxidation of the carbonaceous feedstock to obtain a mixture comprising hydrogen and carbon monoxide, (b) performing a Fischer-Tropsch reaction using the mixture as obtained in step (a) and recovering an off-gas from the Fischer-Tropsch reaction and a paraffin product, (c) hydrogenating at least a part of the off-gas from the Fischer-Tropsch reaction using a steam/off-gas mol ratio in the range of between 0.7 and 1.5 and a catalyst comprising copper and zinc and/or a catalyst comprising copper and manganese, and (d) preparing a hydrogen comprising gas from at least a part of the off-gas from the Fischer-Tropsch reaction. | 07-04-2013 |
