The development of biomass gasification technology towards market penetration in China
Biomass is the second most frequently used fuel, after coal, in China, which accounts for 20% of primary energy consumption. Though the main usage of biomass is for household cooking, the newly developed biomass gasification technology, especially the circulating fluidized bed gasification (CFBG) technology, has laid the foundations for allowing biomass gasification industry penetration into the ...

Co-gasification of wood and polyethylene with the aim of CO and H2 production
This article describes the gasification of polyethylene–wood mixtures to form syngas (H2 and CO) with the aim of feedstock recycling via direct fermentation of syngas to ethanol. The aim was to determine the effects of four process parameters on process properties that give insight into the efficiency of gasification in general, and particularly into the optimum gasification conditions for the ...

Fluidized Bed Biosolids Disposal Gasification Case Study
Summary: In 2007, the Sanford, Florida, Utility Department sought to identify an onsite biosolids management and disposal system that could be integrated within their South Sanford Water Treatment Facility. The intended biogasification system would be a cost effective long–term solution, that is regulatory compliant and environmentally ...

Biomass gasification with pure steam in fluidised bed: 12 variables that affect the effectiveness of the biomass gasifier
Biomass gasification in fluidised bed with pure steam has already generated a 60 vol.%, dry basis, H2 rich gas that was increased to 70–80 vol.% H2 by using a CO2 sorbent in the gasifier bed. A tar content as low as 0.25 g/Nm³ has also been reported when an active catalyst is used in the gasifier bed. Biomass gasification in fluidised bed with pure steam, therefore, has some potential ...

Air gasification of Malaysia agricultural waste in a fluidised bed gasifier
Hydrogen production from agricultural waste has been investigated experimentally using a bench-scale fluidised bed gasifier with 60 mm diameter and 425 mm height. During the experiments, the fuel properties and the effects of operating parameters such as gasification temperatures (800?900?C), fluidisation ratio (2.0?3.33 m/s), static bed height (10?30 mm) and equivalence ratio (0.16?0.46) were ...

Fluidised bed combustion and gasification of rice husk and rice straw – a state of art review
Rice is cultivated in all the main regions of world. The worldwide annual rice production is 666 million tons for the year 2008. The combustion and gasification of rice husk/rice straw in fluidised bed reactors seems to be an attractive possibility of future for power generation, the solution of waste disposal problems and the reduction of greenhouse gases. In this paper, overview of fluidised ...

Research on gasification process of loose biomass material with oxygen-enriched air in fluidised bed gasifier
Fluidised bed gasification technology with oxygen-enriched air suitable for gasifying loose biomass materials was developed. Gasification experiments with different biomass materials such as rice straw, rice hull, wheat straw, sawdust and municipal wastes, were carried out. The tests showed that biomass materials can be gasified continuously at a temperature between 600 and 750°C. The heating ...
