Publication number: 20130058855Abstract: A method of reforming a gasification gas, in order to decompose the impurities comprised in the gas, and a use of a precious metal catalyst in the pre-reforming of gasification gas. The gas can be brought into contact with a metal catalyst in the presence of an oxidizing agent. The reformation can be carried out in several stages, in which case at least in one of the first catalytic zones a noble metal catalyst can be used, and in a secondary reforming stage which follows the first, preliminary reforming zone, the catalyst that can be used is a metal catalyst. Oxygen can be fed separately into each of the catalyst zones.

Publication number: 20120309856Abstract: Method of producing a hydrocarbon composition in which a biomass raw-material is gasified to produce a raw syngas containing carbon monoxide, carbon dioxide and hydrogen, the hydrogen-to-carbon monoxide ratio being about 0.5 to 1.7. A part of the impurities is removed to produce a clean syngas which is fed into a Fischer-Tropsch reactor where a significant part of the carbon monoxide and hydrogen is converted to a hydrocarbon composition containing C4-C90 hydrocarbons. A hydrocarbon composition is recovered which mainly contains hydrocarbons which are solid or semisolid at ambient temperature and pressure and an off-gas of the Fischer-Tropsch reactor, including hydrocarbons which are gaseous at ambient temperature and pressure, is used for producing hydrogen gas. By introducing hydrogen into the clean syngas, the hydrogen to carbon monoxide ratio can be increased and by using off-gas-produced hydrogen, the capacity of the process is significantly improved.Type: ApplicationFiled: May 30, 2012Publication date: December 6, 2012Applicant: Neste Oil OyjInventors: Isto EILOS, Ilkka Hiltunen, Sebastian Johansson, Esa Kurkela, Pekka Simell, Sami Toppinen
