Biomass gasification is an attractive technology and one of the pathways for producing hydrogen. Due to variable seasons low calorific value biomass, addition coal in gasifier suggested because has a high carbon-to-hydrogen ratio. In general, gaseous product obtained always contains amount carbon dioxide, therefore, co-gasification biomass should integrate with calcium looping dioxide capture p...

Much attention has been placed on finding efficient processes for the production of ethanol and other biofuels. One area that shows promise is the conversion of synthesis gas (syngas) to ethanol and hydrogen by both thermochemical and microbiological methods. Two promising methods for creating syngas are the gasification of plant biomass and the pyrolysis of carbonbased waste products. Overall ...

Background: Biofuels may play a significant role in regard to carbon emission reduction in the transportation sector. Therefore, a thermochemical process for biomass conversion into synthetic chemicals and fuels is being developed at the Karlsruhe Institute of Technology (KIT) by producing process energy to achieve a desirable high carbon dioxide reduction potential. Methods: In the bioliq proc...

The gasification of pine and mixed-hardwood chips has been carried out in a pilot-scale system at a range of gas flow rates. Consuming w17e30 kgh 1 of feedstock, the producer gas was composed of w200 dm m 3 carbon monoxide, 12 dm m 3 carbon dioxide, 30 dm m 3 methane and 190 dm m 3 hydrogen, with an energy content of w6 MJ m 3 for both feedstocks. It was found that the efficiency of the system ...

PROCESSES – Biomass combustion is a carbon-free process because the resulting CO2 was previously captured by the plants being combusted. At present, biomass co-firing in modern coal power plants with efficiencies up to 45% is the most cost-effective biomass use for power generation. Due to feedstock availability issues, dedicated biomass plants for combined heat & power (CHP), are typically of ...

Introduction Gasifying biomass to produce a combustible gas provides the possibility for much more efficient overall conversion of a given biomass resource into electric power than is possible with traditional combustion-based technologies. In particular, gasified biomass can be used to power internal combustion engines (ICEs), gas turbines, and fuel cells, all of which are able to produce elec...
