Biomass gasification for synthesis gas production and applications of the syngas

Abstract

Synthesis gas from biomass can be produced and utilized in different ways. Conversion of biomass to synthesis gas can be done either in fluidized bed or entrained flow reactors. As gasification agent oxygen, steam, or mixtures are used. The most common use of biomass gasification in the last decades has been for heat and/or power production. Nowadays, the importance of transportation fuels from renewables is increased due to environmental aspects and growing fossil fuels prices. That is why the production of Fischer-Tropsch (FT) liquids, methanol, mixed alcohols, substitute natural gas (SNG), and hydrogen from biomass is now in focus of view. The most innovative and interesting ways of synthesis gas utilization and projects, BioTfueL or GoBiGas, BioLiq, Choren, etc. are discussed here. Further the microchannel technology by Oxford Catalysts and distributed production of SNG in decentral small scale are presented. The synthesis platform in Güssing, Austria is also presented. The FT liquids, hydrogen production, mixed alcohols, and BioSNG, these are the projects associated with the FICFB gasification plant in Güssing. Also the principle and examples of sorption-enhanced reforming to adjust H 2 /CO ratio in product gas during the gasification is described. Finally, in the conclusion also an outlook for the thermochemical pathway to transportation fuels is given.

Remarkably efficient CoGa catalyst with uniformly dispersed and trapped structure for ethanol and higher alcohol synthesis from syngas

“…Among the alcohol products, the fraction of ethanol and higher alcohols is up to 92.8%. According to GC-MS analysis results (see the Supplementary Information), the alcohol products are composed of 1-alcohols with the carbon number ranging up to C 16 . As expected, unwanted CO 2 is under control for all the four catalysts.…”

“…In addition to coal gasification [10,11] and natural gas oxidation [12][13][14], syngas can be efficiently manufactured from renewable dry biomass [15,16]. The catalytic synthesis of ethanol and higher alcohols from syngas is a reliable method of energy and fuel production independent of fossil resources.…”

Influence of coated olivine on the conversion of intermediate products from decomposition of biomass tars during gasification

“…As a consequence, the product gas from this specific gasification is practically free of nitrogen and can be further used as a valuable synthesis gas for the production of a variety of different end products [2]. Examples of such products are bio-methane [3,4], Fischer-Tropsch bio-diesel [5,6], pure hydrogen [7][8][9], or mixed alcohols [10]. Therefore, this technology is also referred to as polygeneration.…”

The bioliq® Entrained‐Flow Gasifier – a Module for the German Energiewende

“…Bei der Wirbelschichtvergasung wurden neue Technologievarianten speziell für den Einsatz von Holz entwickelt. Das an der TU Wien entwickelte Duale‐Wirbelschichtverfahren erzeugt im allothermen Betrieb ein stickstofffreies, teerarmes Synthesegas, das sowohl für die energetische als auch für die stoffliche Nutzung geeignet ist. Mehrere technische Systeme im Kapazitätsbereich bis 10 MW wurden nach diesem Verfahrensprinzip realisiert (z.…”
