PDF Tar reforming through autothermal partial oxidation
On the other hand, biomass can be gasified into syngas and then synthesized be reacted with raw biogas after the digester in a separate biological reactor, After cleaning and conditioning of the syngas in order to obtain a gas suitable for the synthesis reactions, DME is synthesised catalytically via While the heat demand for the endothermic reactions of pyrolysis and gasification is relatively small in Synthesis gas from biomass for fuels and chemicals. Syngas can be produced from many sources, including natural gas, coal, biomass, or virtually any hydrocarbon feedstock, by reaction with steam or oxygen. Pris: 734 kr. häftad, 2012.

Carbon dioxide reforming of methane produces synthesis gas with a low hydrogen to carbon monoxide ratio, which is desirable for many industrial synthesis processes. This reaction also has very important environmental implications since both methane and carbon dioxide contribute to the greenhouse effect. Converting these gases into a valuable feedstock may significantly reduce the atmospheric "Synthesis gas" can be produced by the catalytic re-forming of methane with steam. The reactions are: CH_() + H2O(g) → CO(g) + 3H2(8) CO(g) + H20(8) -+ CO2(g) + H2(8) Assume equilibrium is attained for both reactions at I bar and 1300 K.

Synthesis gas can be reacted or reformed to make methanol through highly exothermic reactions: CO + 2H 2 ↔ CH 3 OH ( 1 ) Δ H r ( 255 ∘ C ) = - 91.9 kJ / mol CO 2 + 3H 2 ↔ CH 3 OH ( 1 ) + H 2 O Δ H r ( 255 ∘ C ) = - 51.9 kJ / mol Synthesis gas production 1. Introduction There are a number of technologies available to produce syngas, these technologies are summarized in Fig. 1. Of the technologies shown in Fig. 1, steam methane reforming (SMR) is the most common.
