Investigation of Air and Air-Steam Gasification of High
For air-steam gasification, water was introduced to the reactor to provide different steam/biomass (S/B) ratios at a fixed temperature of 715 oC and a fixed ER of 0.12, with gas sampling as for air alone. 2.4 Gas Analysis The concentrations of H2, N2, CO, CO2 and CnHx were measured by a micro-gas chromatograph CP-4900
Frontiers | Experimental Gasification of Coffee Husk Using
This work discusses results on temperature profile, syngas composition, High Heating Value, and efficiency of a Coffee Husk counter-current fixed-bed gasification process, in which oxygen-steam blends were used as an oxidizing agent. The experimentation was carried out for various Equivalence Ratios (ER) and Steam-Fuel Ratios (SF), whose ranges were [1.6–5.6] and [0.4–0.8], respectively
Biomass gasification under external heating and using steam
4. Conclusions. This work presents the numerical analysis of gasification for a high moisture content biomass using external heat supply, this process was analyzed considering the high potential of agroindustry residues in Colombia which have characteristics similar to the analyzed. According to results, using a biomass with a moisture content
High Temperature Air/Steam Gasification (HTAG) Of Biomass
3, in which 40 kg/h biomass feeding rate and 80 kg/h Steam flow rate is maintained gives High LHV, high H2/CO ratio and more CO/CO2 ratio among the rest case studies. Further improvement can be done within the reactor, increase in retention time and variation of more parameters can examine, in order to get the optimum result in future.
Co-processing methane in high temperature steam gasification
High temperature steam gasification/reforming of biomass-methane mixtures was carried out in an indirectly heated entrained flow reactor to analyze the feasibility of controlling the output composition of the major synthesis gas products: H(2), CO, CO(2), CH(4).
Obtaining and Evaluation of Synthesis Gases from Biomass
Barranquilla – Colombia – June 21st and 22nd - 2018 2 The Computational Fluid Dynamics (CFD) using a validated gasification model have been used to examine the effect of biomass quantity on a biomass co-production process. The model was validated with actual operating data from an integrated gasification combined cycle plant located in

Biomass Gasifier “Tars”: Their Nature, Formation, and Conversion
gasification that condensed under operating conditions of boilers, transfer lines, and internal combustion engine (ICE) inlet devices. Such a definition requires a more detailed chemical explanation in light of the greatly expanded uses proposed for both high- and low-energy gas from a variety of biomass and waste materials.
Ultra-high temperature steam gasification of biomass - White
May 02, 2014 · In this research, hydrogen production from conventional slow pyrolysis, flash pyrolysis, steam gasification and catalytic steam gasification of various biomass samples including rice husk, wood pellets, wheat straw and sugarcane bagasse was investigated at ultra-high temperature (~1000 °C).
Ultra-High Temperature Steam Gasification of Biomass and
Oct 19, 2007 · Experimental results are presented on the gasification of several waste products using high-temperature steam as the gasification media. Four cellulose-rich surrogate waste products (paper, cardboard, and wood pellets) were gasified with high-temperature steam at different temperatures in the range of 700 to 1,100°C. Gasification is an efficient method for clean conversion of waste to
Simulation of Adiabatic Gasification of Corn Straw using Air
The biomass gasification is a thermal process to produce syngas which can be an alternative solution since biomass is a neutral fuel in the production of CO 2 . Additionally, biomass can also be used as fuel in combustion processes for power generation; however, these processes usually occur at high temperatures that
