标题 :Method for the production of hydrogen-containing gaseous mixtures
发明人：KINDIG JAMES KELLY; WEYAND THOMAS E
权利人:ALCHEMIX CORP
摘要:A method for the production of a hydrogen-containing gas composition, such as a synthesis gas including hydrogen and carbon monoxide. The molar ratio of hydrogen to carbon monoxide (H 2 :CO) in the synthesis gas can be well-controlled to yield a ratio that is adequate for the synthesis of useful products such as methane or methanol, without the need to remove carbon oxides from the gas stream to adjust the ratio.

标题:Synthesis of Ammonia Using Cycle-Generated Hydrogen Sulfide
发明人：HAMERS ROBERT; BACHMAN BENJAMIN
权利人:WISCONSIN ALUMNI RES FOUND
摘要:Improved methods of synthesizing ammonia from hydrogen sulfide and lithium nitrate are disclosed. Specifically, in a continuous cycle, hydrogen sulfide reactant is regenerated from the elemental sulfur that is extracted from a product of the ammonia synthesis, and the regenerated hydrogen sulfide is fed back into the ammonia synthesis reaction. The cycle that regenerates the hydrogen sulfide uses either a water-containing or a water and carbon-containing feedstock to facilitate the regeneration of the hydrogen sulfide from the elemental sulfur.
