“…It is attributed to more H 2 and C x H y (x ¼ 1, 2) being oxidized into H 2 O at higher Fe 2 O 3 /C values. Since the phase transition of steam occurs from gas to liquid in the condensation process, the gas yield starts reducing [27]. With the increase of Fe 2 O 3 /C, more lattice oxygen is available to react with carbon, thus more carbon in biomass is converted into synthesis gas.…”

“…Therefore, the carbon conversion increases from 74.56% to 87.31% when the Fe 2 O 3 /C varies in the range of 0.08e0.46. The gasification efficiency is an important parameter to evaluate the performance of biomass gasification, which is defined as the ratio of the calorific value of the gas products from unit mass biomass gasification to the total calorific value of the unit mass of biomass [27], in which the calorific value of gas products is determined by the product of gas LHV and gas yield. Over the ratio of Fe 2 O 3 /C varying from 0.08 to 0.23, the gasification efficiency of BGCL increases rapidly from 75.03% to 83.31% as a consequence of the increase of gas yield offsetting the decrease of gas LHV.…”

“…Reza [27] and Gao et al [28] summarized the gasification reaction as an endothermic reaction that will decompose biomass or plastics to produce hydrogen-rich syngas at a temperature between 650 and 1200°C. The involved reactions are the char gasification reaction (∆H = 131.5 kJ mol −1 ), as shown in Eq.…”

The co-gasification of beech-wood and polyethylene has been investigated in a lab-scale fluidised-bed reactor in the presence of four different types of bed materials (silica sand, olivine, Na-Y zeolite and ZSM-5 zeolite). ZSM-5 zeolite is very effective as a catalytic bed material in fluidized-bed reactor for wood-only gasification and cogasification in terms of high hydrogen production and CGE. Na-Y zeolite is more effective compared with ZSM-5 zeolite in co-gasification of the beech-wood and polyethylene process. The catalytic activity in co-gasification of beech-wood and polyethylene can be ranked accordingly: Na-Y zeolite > ZSM-5 zeolite > olivine. In general, higher amounts of steam injected in the fluidized-bed reactor and more polyethylene would lead to higher hydrogen production in the co-gasification process.

“…4 Gas production by biomass gasification is a complex process and is affected by a number of factors, such as: gasifier type, gasifier geometry, biomass type, gasifier pressure, gasification temperature, gasification agent, and the mode of gas-solid contact. [5][6][7][8] Among these factors, the type of gasifier, gasification temperature, and gasification agent plays an important role in determining gasification performance. 6 The addition of pure steam as gasification agent in biomass gasification process makes it possible to obtain high-grade and relatively higher H 2 content product gas.…”

In this paper, thermochemical biomass intermittent gasification was performed in a fluidized-bed reactor with pure steam as gasification agent. A single fluidized bed two-stage gasification process, also known as intermittent gasification process, which involves the time segregated hybridization of coal-combustion and steam biomass-gasification stages in the same vessel, was employed. This research aims to explore the influences of gasification temperature (T) and steam-biomass ratio (S/B) on composition, energy and exergy distribution, as well as energy and exergy conversion efficiencies of the product gas (biomass-gas). Over the ranges of the test conditions used, the total concentration of H 2 and CO in the biomass-gas varies between 57.9% and 80.8%, and the exergy and energy efficiencies of the biomass-gas are in the ranges of 54.61%-35.52% and 82.91%-60.78%, respectively. The results show that the chemical exergy values of the biomass-gas are 13.50 to 17.71 times as the corresponding physical exergy values, whereas the chemical energy values are 6.91 to 9.45 times as the corresponding physical energy values. The total energy values of the biomass-gas are higher than the corresponding exergy values, this result in higher energy efficiencies of the biomass-gas. Higher temperature contributes to higher CO and H 2 content, physical and chemical energy values, physical and chemical exergy values, as well as energy and exergy efficiencies of the biomass-gas. The steam to biomass ratio is optimal in the intermediate levels for maximal energy and exergy efficiencies of the biomass-gas. V C 2013 AIP Publishing LLC. [http://dx.
