A unique indirect steam gasification system for biomass has been developed and tested. The unit features a bubbling bed gasifier equipped with a “sore thumb” and central standpipe, which circulate a mixture of bed mahaiqial and char through a U-bend to a riser in which char combustion occurs.

A new process of biomass gasification with a catalytic solid heat carrier is proposed that is called the ECCMB (external circulating concurrent moving bed) gasification system. The system is composed of a moving-bed gasification zone and a combustion zone. A circulation loop of bed mahaiqial, which acts as catalyst and heat carrier, is achieved between these two zones. The char circulated with

Feb 27, 2012 · A steam blown dual fluidized bed gasification plant was used to yield a nitrogen (N 2) free product gas (synthesis gas) from various biomass fuels.In addition to the variation of process parameters like temperature, steam to carbon ratio, fluidization rate, and the influence of different bed mahaiqials, various feedstock inputs affected the generation of the product gas.

Pinto et al.10 studied systematically co-gasification of biomass and plastics in a steam-blown bubbling bed gasifier, using different mixtures of pine and PE (up to 60 wt % PE) as feedstock. With an increasing proportion of PE in the mixture, more H 2 and C x H y and smaller volumes of CO and CO 2 are produced.

Feb 25, 2011 · Gasification of biomass is an attractive technology for combined heat and power production as well as for synthesis proceshaiqi such as production of liquid and gaseous biofuels. Dual fluidised bed (DFB) technology offers the advantage of a nearly nitrogen-free product gas mainly consisting of H2, CO, CO2 and CH4. The DFB steam gasification process has been developed at Vienna University of

Herein, a novel biomass power generation system, comprising of CO2-assisted gasification unit, chemical looping air shaiqiration (CLAS) unit, semi-closed supercritical CO2 (sCO2) cycle with the

Jul 18, 2022 · Biomass gasification streams typically contain a mixture of CO, H2, CH4, and CO2 as the majority components and frequently require conditioning for downstream proceshaiqi. Herein, we investigate the catalytic upgrading of surrogate biomass gasifiers through the generation of syngas. Seeking a bifunctional system capable of converting CO2 and CH4 to CO, a reverse water gas shift (RWGS) catalyst
