From biomass to syngas, fuels and chemicals – A review
Abstract
The gasified form of biomass is called syngas which can be further converted to fuels, liquid products and other chemicals via thermo-chemical and bio-chemical processes. After pretreatment of biomass, gasification occurs at high temperature in the presence of oxidizing agents. The biomass is oxidized to produce syngas through several steps. Syngas contains mainly CO, H2 and small amounts of impurities and these impurities are removed based on downstream usage of the syngas. Through gasification, all the carbon content in the biomass is converted into syngas and the main use of biomass syngas is the generation of heat / power. Common chemicals obtained from the syngas are: methanol from CO and H2; ammonia from N2; H2 and liquid hydrocarbons by Fisher-Tropsch synthesis. Different types of catalysts are used in the thermo-chemical routes like sulphide type mixed alcohol catalyst, Rh/SiO2, Rh/MCM-41, Cu/MCM-41, from which oxygenates and hydrocarbon products can also be produced. In gas fermentation, ethanol is produced using different bio catalyst and CO2/H2 is consumed in this process. Many other chemicals such as butanol, acetic acid, acetone also can be synthesized. When compared to thermo-chemical routes, gas fermentation operates at low pressure and low temperature and produces ethanol with high carbon conversion efficiency.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
