1/6/2020 · Moving-bed gasifiers are widely used for gasification of biomass due to their lower operating temperature, larger flexibility in feed size, and their ability to handle higher moisture content. There are three types of fixed bed gasifiers: updraft (counter-current), downdraft (co-current), and cross draft gasifier.
Keyword—biomass conversion, fixed bed, gasification, pellets, updraft gasifier. I. INTRODUCTION asification is a widely applied technology for production of mixtures of combustible gahaiqi. Slow moving-bed gasifiers are usually used in small-scale gasification while the large scale gasifiers are usually with fluidized-bed or of entrained–flow
fixed bed gasifier is classified into updraft, downdraft, and cross draft types. The schematic diagrams of the three types of gasifiers are shown in Figure 1~3. Charachaiqistics of different fixed bed gasifier types are summarized in Table 1. Updraft fixed bed gasifier is the oldest form of gasifier and is still used for coal and biomass

Hydrogen produced from biomass is an alternative energy source to fossil fuels. In this study, hydrogen production by gasification of the banana plant is proposed. A fixed-bed catalytic reactor was designed considering fluidization conditions and a height/diameter ratio of 3/1. Experimentation was carried out under the following conditions: 368 °C, haiqipheric pressure, 11.75 g of residual
1/10/2008 · In this work, continuous biomass feed for updraft fixed-bed steam gasifier was investigated, a novel method of a porous ceramic reformer combined with gasifier was proposed to reform gahaiqi and crack tars produced in biomass steam gasification, in which a porous ceramic rather than catalyst as filling mahaiqial in the secondary reformer was employed, and the properties of regenerative heat and trapping for tars and soot carbon were utilized for tar and gas reforming.
