Abstract: Inspired by the promising hydrogen production in the solar thermochemical (STC) cycle based on non-stoichiometricIn the reduction step, MoO : CH = 2 and 1020 K< <1600 K are found to be most favorable for syngas selectivityCompared to the STC cycle without CH , the introduction of methane yields a much higher hydrogen production

Energy and exergy analysis of syngas production from different biomasses through air-steam gasification

S. Rupesh,C. Muraleedharan,P. Arun

Frontiers in Energy 2020, Volume 14, Issue 3,   Pages 607-619 doi: 10.1007/s11708-016-0439-1

Abstract: Gasification is a thermo-chemical reaction which converts biomass into fuel gases in a reactor. The efficiency of conversion depends on the effective working of the gasifier. The first step in the conversion process is the selection of a suitable feedstock capable of generating more gaseous fuels. This paper analyses the performance of different biomasses during gasification through energy and exergy analysis. A quasi-equilibrium model is developed to simulate and compare the feasibility of different biomass materials as gasifier feedstock. Parametric studies are conducted to analyze the effect of temperature, steam to biomass ratio and equivalence ratio on energy and exergy efficiencies. Of the biomasses considered, sawdust has the highest energy and exergy efficiencies and lowest irreversibility. At a gasification temperature of 1000 K, the steam to biomass ratio of unity and the equivalence ratio of 0.25, the energy efficiency, exergy efficiency and irreversibility of sawdust are 35.62%, 36.98% and 10.62 MJ/kg, respectively. It is also inferred that the biomass with lower ash content and higher carbon content contributes to maximum energy and exergy efficiencies.

Process analysis of syngas production by non-catalytic POX of oven gas

Fuchen WANG , Xinwen ZHOU , Wenyuan GUO , Zhenghua DAI , Xin GONG , Haifeng LIU , Zunhong YU ,

Frontiers in Energy 2009, Volume 3, Issue 1,   Pages 117-122 doi: 10.1007/s11708-008-0078-2

Abstract: A non-catalytic POX of oven gas is proposed to solve the problem of secondary pollution due to solid wastes produced from the great amount of organic sulfur contained in oven gas in the traditional catalytic partial oxidation (POX) process. A study of the measurement of flow field and a thermodynamic analysis of the process characteristics were conducted. Results show that there exist a jet-flow region, a recirculation-flow region, a tube-flow region, and three corresponding reaction zones in the non-catalytic POX reformer. The combustion of oven gas occurs mainly in the jet-flow region, while the reformation of oven gas occurs mainly in the other two regions. Soot would not be formed by CH cracking at above 1200°C. Since there are very little C hydrocarbons in oven gas, the soot produced would be very tiny, even if they underwent cracking reaction. The integrated model for entrained bed gasification process was applied to simulate a non-catalytic POX reformer. It indicated that the proper oxygen-to-oven gas ratio is 0.22–0.28 at different pressures in the oven gas reformation process.
