Entrained Flow Gasification of Biomass

Qin, Ke

DTU Chemical Engineering — 2012

The present Ph. D. thesis describes experimental and modeling investigations on entrained flow gasification of biomass and an experimental investigation on entrained flow cogasification of biomass and coal. A review of the current knowledge of biomass entrained flow gasification is presented. Biomass gasification experiments were performed in a laboratory-scale atmospheric pressure entrained flow reactor with the aim to investigate the effects of operating parameters and biomass types on syngas products. A wide range of operating parameters was involved: reactor temperature, steam/carbon ra...

High-temperature entrained flow gasification of biomass

Qin, Ke; Lin, Weigang; Jensen, Peter Arendt; Jensen, Anker Degn

Fuel — 2012, Volume 93, pp. 589-600

Biomass (wood and straw) gasification has been studied in a laboratory scale atmospheric pressure entrained flow reactor. Effects of reaction temperature, steam/carbon molar ratio, excess air ratio, and biomass type on the solid, liquid and gas products were investigated. The biomass was completely

Characterization of Residual Particulates from Biomass Entrained Flow Gasification

Qin, Ke; Lin, Weigang; Fæster, Søren; Jensen, Peter Arendt; Wu, Hao; Jensen, Anker Degn

Energy and Fuels — 2013, Volume 27, Issue 1, pp. 262-270

Biomass gasification experiments were carried out in a bench scale entrained flow reactor, and the produced solid particles were collected by a cyclone and a metal filter for subsequent characterization. During wood gasification, the major part of the solid material collected in the filter is soot. Scanning electron microscopy (SEM) images coupled with energy dispersive spectroscopy (EDS) show agglomerated nanosize spherical soot particles (<100 nm) that are very rich in carbon. In comparison to wood gasification, the soot content in the filter sample from straw gasification is quite low...

The Release Behavior of Potassium and Sodium in the Biomass High-Temperature Entrained-Flow Gasification

Chen, Qing; Zhou, Jin Song; Mei, Qin Feng; Luo, Zhong Yang

Applied Mechanics and Materials — 2011, Volume 71-78, pp. 2434-2441

Experiments were performed to investigate the release behavior of potassium and sodium in the biomass high-temperature entrained-flow gasification with the addition of acid oxide SiO2, basic oxide MgO, amphoteric oxide Al2O3. The results showed that the volatilization of alkali was found to strongly depend on temperature. High gasification temperature strengthened the alkali release. When the reactor temperature was 1200°C, the volatilization of alkali species were about 37.87% for K and 71.14% for Na. Three additives all favored the retention of potassium a...

Biomass Gasification Behavior in an Entrained Flow Reactor: Gas Product Distribution and Soot Formation

Qin, Ke; Jensen, Peter Arendt; Lin, Weigang; Jensen, Anker Degn

Energy and Fuels — 2012, Volume 26, Issue 9, pp. 5992-6002

Biomass gasification and pyrolysis were studied in a laboratory-scale atmospheric pressure entrained flow reactor. Effects of operating parameters and biomass types on the syngas composition were investigated. In general, the carbon conversion during biomass gasification was higher than 90
