Thermodynamic investigation of SNG production based on dual fluidized bed gasification of biogenic residues

Fluidized Bed Reactor System for the Gasification of Waste Materials and Biogenic Residues

The conversion of various solid low-cost fuels into valuable gas with high energy content is attracting increasing interest within the chemical industry and the energy supply sector. For the gasification of carbonic fuels, fluidized bed processing based on the dual fluidized bed concept is utilized preferably. Dual fluidized bed gasification technology greatly intensifies the conversion of the ...

Effect of Fe-olivine on the tar content during biomass gasification in a dual fluidized bed

Prediction of Rice Husk Gasification on Fluidized Bed Gasifier Based on Aspen Plus

A biomass gasification model was developed using Aspen Plus based on the Gibbs free energy minimization method. This model aims to predict and analyze the biomass gasification process using the blocks of the RGibbs reactor and the RYield reactor. The model was modified by the incomplete equilibrium of the RGibbs reactor to match the real processes that take place in a rice husk gasifier. The mo...

Fluidized-bed gasification of dairy manure by Box-Behnken design.

Application of excessive animal manure to the land may cause some environmental problems such as eutrophication of surface waters, degradation of ground water quality, and threats to human health. This paper reports an experimental study on the technology of biomass gasification to treat animal waste by analysing the effects of key operating parameters on gasification. In this research, dairy m...

GASIFICATION vs COMBUSTION OF WASTE/BIOMASS IN FLUIDIZED BED REACTORS

This paper presents a comparison of commercial fluidized bed gasifiers and combustors used to recover energy from municipal solid wastes and biomass. The work reported here is excerpted from four case studies prepared for the International Energy Agency’s Bioenergy Agreement, under Task 23 (Energy from Thermal Conversion of MSW and RDF, 1998-2000) and Task 36 (Energy from Integrated Solid Waste...
