Processes for increasing hydrogen recovery are described. The processes use cold carbon dioxide-enriched product from the carbon dioxide recovery system to chill the hydrogen PSA feed stream. The carbon dioxide-enriched product stream comprises a supercritical carbon dioxide stream or a liquid carbon dioxide stream. The synthesis gas stream is typically chilled to a temperature in a range of 0? C. to 40? C. The temperature of the chilled synthesis gas stream is typically at least 10? C. lower than the temperature of the synthesis gas before chilling.

A method for gas separation, purification and clarification by FTrPSA uses the temperature and pressure of different raw gases as well as the differences in adsorption separation coefficients and physicochemical properties among all components in the raw gases at a temperature range of 80-200 C. and a pressure range of 0.03-4.0 Mpa, regulates the adsorption or desorption regeneration operation in the PSA cycle process by coupling various separation methods, and expands the adsorption theory that the PSA or TSA separation process is limited to the cyclic operation of adsorption and desorption regeneration through pressure or temperature changes, thus realizing the gradient utilization of energy in the process of gas separation, purification and clarification as well as the easy-to-match and easy-to-balance cyclic operation of adsorption and desorption regeneration in the process of intercooling & shallow-cooling and medium & high-temperature PSA separation to separate, purify and clarify various raw gases.

The invention is directed to a process for the preparation of a syngas comprising hydrogen and carbon monoxide from a methane comprising gas, which process comprises the steps of: (a) reacting the methane comprising gas with an oxidizing gas in an autothermal reformer to obtain a hot raw syngas comprising carbon monoxide and hydrogen; (b) cooling the hot raw syngas resulting from step (a) to obtain the syngas, wherein step (b) comprises cooling the hot raw syngas by indirect heat exchange against the methane comprising gas used in step (a) and wherein sulphur is added upstream of cooling step (b). The invention also relates to a process for the preparation of hydrocarbon products in which a feed syngas is prepared in the process as described above followed by a desulphurization treatment and the desulphurized syngas is subsequently converted into hydrocarbon products in a Fischer-Tropsch process.

A fuel treatment device (2) converts a hydrocarbon-containing fuel into a fuel for a fuel cell (3). The fuel treatment device (2) has for this purpose a mixture formation space (7) for forming and processing a mixture of fuel and another component, a reformer (8) for converting the mixture into a synthesis gas and a desulfurization stage (9) for removing sulfur from the synthesis gas or from the mixture. The reformer (8) and desulfurization stage (9) are arranged adjacent to each other in a housing (10) along an axis of the housing (10).

A chemical looping combustion (CLC) process for sour gas combustion is integrated with a gas turbine combined cycle and a steam generation unit, and is configured to provide in-situ removal of H.sub.2S from the sour gas fuel by reacting the H.sub.2S with a oxygen carrier at a location within the fuel reactor of the CLC unit. The process is also configured such that oxygen-rich exhaust gases from the gas turbine combined cycle is used to feed the air reactor of the CLC unit and re-oxidize oxygen carriers for recirculation in the CLC unit.
