Gasification of biomass in supercritical water (SCWG)
Conversion of wet biomass via gasification in supercritical water is a promising technology for the production of hydrogen and methane from renewable resources. The properties of water above the critical point enable reactions for the fast degradation of biomass and generation of a product gas consisting of hydrogen, methane, higher hydrocarbons and carbon dioxide without disturbing sulphurand ...
متن کاملSupercritical Water Gasification of Biomass and Organic Wastes
With the exhaustion of fossil fuels and the severe pollution of the environment, it’s urgent to find substitute renewable energy resources. Biomass is a kind of widespread and abundant renewable resource with lower sulfur content than fossil fuels, so the pollution to environment from biomass usage is much slighter than that from fossil fuels usage. Besides, zero emission of CO2 can be realized...

Two wet biomass gasification processes, supercritical water gasification and biomethanation, were evaluated from energy, environmental, and economic aspects. Gasification of 1 dry-t/d of water hyacinth was taken as a model case. Assumptions were made that system should be energetically independent, that no environmentally harmful material should be released, and that carbon dioxide should be re...
متن کاملThermodynamic Analysis of Supercritical Water Gasification of Microalgae Biomass for Hydrogen and Syngas Production
Supercritical water gasification (SCWG) is an alternative thermochemical technology for the conversion of wet biomass in a high heat value product gases, such as syngas and hydrogen. Algal biomass has been suggested as one promising option to produce biomass for use as fuels and chemical feedstocks with high area-specific yields. In this study, the thermodynamic analysis of SCWG of microalgae b...
متن کاملCatalytic gasification of glycerol in supercritical water
The conversion of glycerol in supercritical water (SCW) was studied at 510 – 550°C and a pressure of 350 bars using both a bed of inert and non-porous ZrO2 particles (hydrothermal experiments), and a bed of 1 % Ru/ZrO2 catalyst particles. Experiments were conducted with a glycerol concentration of 5 wt% in a continuous isothermal fixed-bed reactor at a residence time between 2 and 10 s. Hydroth...
