    摘要： Disclosed embodiments provide a system and method for producing hydrocarbons from biomass. Certain embodiments of the method are particularly useful for producing substitute natural gas from forestry residues. Certain disclosed embodiments of the method convert a biomass feedstock into a product hydrocarbon by hydropyrolysis. Catalytic conversion of the resulting pyrolysis gas to the product hydrocarbon and carbon dioxide occurs in the presence of hydrogen and steam over a CO2 sorbent with simultaneous generation of the required hydrogen by reaction with steam. A gas separator purifies product methane, while forcing recycle of internally generated hydrogen to obtain high conversion of the biomass feedstock to the desired hydrocarbon product. While methane is a preferred hydrocarbon product, liquid hydrocarbon products also can be delivered.

    摘要： There is provided a method for producing hydrocarbon compounds. The method comprising: producing a syngas by introducing a fuel stream comprising a reformable fuel into a reforming system (steam reformer, autothermal reformer, cold plasma reformer and/or internal-reforming fuel cell), and wherein the syngas comprises H2, CO and CO2, and has a ratio of [H2]/[CO] of about 1.4 to about 2.5; producing a decarbonated and dehydrated syngas from the syngas having a ratio of [CO2]/[CO+CO2] of no higher than 0.6; performing a Fischer-Tropsch synthesis on the decarbonated and dehydrated syngas in the presence of a cobalt- or iron-based Fischer-Tropsch catalyst, said Fischer-Tropsch catalyst comprising pellets of trilobe, cylindrical, hollow cylinder or spherical construction with diameter about 0.5 mm to about 3.0 mm and aspect ratio of 1 to 3.5, to produce a product stream comprising the hydrocarbon compounds; and recycling aqueous products and/or tail gas.

    摘要： Catalysts for oxidative sulfur removal and methods of making and using thereof are described herein. The catalysts contain one or more reactive metal salts dispersed on one or more substrates. Suitable reactive metal salts include those salts containing multivariable metals having variable valence or oxidation states and having catalytic activity with sulfur compounds present in gaseous fuel streams. In some embodiments, the catalyst contains one or more compounds that function as an oxygen sponge under the reaction conditions for oxidative sulfur removal. The catalysts can be used to oxidatively remove sulfur-containing compounds from fuel streams, particularly gaseous fuel streams having high sulfur content. Due to the reduced catalyst cost, anticipated long catalyst life and reduced adsorbent consumption, the catalysts described herein are expected to provide a 20-60% reduction in annual desulfurization cost for biogas with sulfur contents ranges from 1000-5000 ppmv compared with the best adsorbent approach.

    摘要： A system for processing a syngas stream including particulate matter, a combustible gas, and acid components is disclosed. The system includes a gasifier vessel configured to produce a raw syngas stream; a gas cooling apparatus configured to cool the raw syngas stream to produce a cooled syngas stream; an HCl and particulate removal apparatus configured to produce a reduced-HCl syngas stream; a first reheat apparatus configured to produce a first reheated syngas stream; a COS and HCN hydrolysis apparatus configured to produce a hydrolyzed syngas stream; an H2S removal apparatus configured to produce a reduced-H2S syngas stream; a second reheat apparatus configured to produce a second reheated syngas stream; an activated carbon bed apparatus configured to produce a polished syngas stream; and a compression and intercooling apparatus configured to compress and cool the polished syngas stream to produce a clean syngas stream.
