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...

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...
متن کاملProcess Design for Supercritical Water Gasification
In this paper the layout of pilot plant (100 kg/h) for the supercritical water gasification (SCWG) of biomass is proposed. The proposed layout involves a reactor, units to separate water and hydrogen, a burner and several heat exchangers. This scheme was also simulated by means of the commercial software Aspen Plus (Aspen Tech, Inc.) in order to state the influence of different parameters such ...
