Processes for producing high biogenic concentration Fischer-Tropsch liquids derived from the organic fraction of municipal solid wastes (MSW) feedstock that contains a relatively high concentration of biogenic carbon (derived from plants) and a relatively low concentration of non-biogenic carbon (derived from fossil sources) wherein the biogenic content of the Fischer-Tropsch liquids is the same as the biogenic content of the feedstock.

The invention relates to a process for removal of unwanted, in particular acidic, gas constituents, for example carbon dioxide and hydrogen sulfide, from a crude synthesis gas containing metal carbonyls by gas scrubbing with a scrubbing medium. According to the invention water is added directly into the feed conduit of the methanol water mixture containing metal sulfides before the introduction thereof into the methanol-water separating column and/or water is injected directly into the methanol-water separating column at at least one point. This avoids deposits or encrustations of metal sulfide particles in the methanol-water separating column.

A fuel cell system for removing carbon dioxide from anode exhaust gas includes: a fuel cell having an anode configured to output an anode exhaust gas comprising hydrogen, carbon monoxide, carbon dioxide, and water; an anode gas oxidizer; and an absorption system configured to receive the anode exhaust gas, the absorption system including: an absorber column configured to absorb the carbon dioxide from the anode exhaust gas in a solvent and to output a resultant gas comprising hydrogen and a hydrocarbon that is at least partially recycled to the anode; and a stripper column configured to regenerate the solvent and to output a carbon dioxide-rich stream. The anode gas oxidizer is configured to receive and oxidize an anode gas oxidizer input stream and at least a portion of the carbon dioxide-rich stream. The anode gas oxidizer input stream comprises a portion of the anode exhaust gas.

Method and system for the combined production of methanol and of ammonia, and method for producing a fuel using methanol, wherein a carbon-containing energy carrier flow and an oxygen flow from an oxygen-producing assembly are fed to a synthesis gas reactor assembly for obtaining a synthesis gas flow with hydrogen and carbon oxides, wherein the synthesis gas flow is fed to a methanol reactor assembly for the partial conversion into methanol, and wherein, from the methanol reactor assembly, a residual gas flow is obtained from which a hydrogen-containing flow is obtained, which is at least partially fed to an ammonia reactor assembly and at least partially converted into ammonia there. In an enrichment step, the molar fraction of hydrogen in the synthesis gas flow obtained from the synthesis gas reactor assembly is increased relative to the molar fraction of carbon oxides prior to the feeding to the methanol reactor assembly.

Plant and process for separation of sulfur-containing components, H.sub.2S, COS and mercaptans from methanol which is used as absorbent within the Rectisol process by hot regeneration of the methanol laden in the absorption and an additional step for separation of the mercaptans from the methanol by stripping.
