Abstract:

A new dual-bed photocatalytic hydrogen production reaction system is proposed in this paper. In this dual-bed system, one bed is photocatalytic hydrogen evolution reaction bed in which I- is oxidized into I2 by a hole and H+ is reduced to H2 by an electron, and the other is the hole-sacrificed agent regeneration bed in which I- is regenerated by reducing I2 with Cu2O. The two reaction beds are connected with two constant flow pumps to form a circulation loop. The hole-sacrificed agent I- can always be renewable by circulating the reaction solution between dual beds. The dual-bed reaction syste

Abstract:

One of the main issues using biomass as fuel in air gasification is the dilution of its product gas by the nitrogen in the air. A dual reactor fluidized bed (DRFB) overcomes this problem in which the gasification and combustion reactions are decoupled and conducted in two separate fluidized bed reactors connected by circulating bed material. The DFRB unit made of 304 stainless steel pipe with a height of 100 and 150 cm, and inner diameters (i.d.) of 15.2 and 5.1 cm for gasifier and combustor respectively. The rice husk as fuel and quartz sand as bed material having the same size of 0.4 - 0.6 m

Abstract:

Biomass is an important renewable energy and making hydrogen-rich syngas from biomass is promising. Dual fluidized bed gasification technology can increase hydrogen content in the syngas. Moreover, steam gasification of biomass coupled with lime-based CO2 capture in a dual fluidized bed can further improve the syngas quality . This paper established a dual fluidized bed gasification model using Aspen plus,in order to explore the effect of different gasification temperatures and steam to biomass ratios on hydrogen content in syngas, providing a theoretical basis for the optimization of operatin

Abstract:

A numerical study on a gas-solid model to predict the particle flow structures of dual support-leg fluidized bed has been conducted. Due to the symmetry motion trajectory of the particles in the dual support-leg fluidized bed, unilateral furnace was taken into account in the model to simplify calculation. The results indicate that, without buffer set on the wall, three different zones can be distinguished in terms of granular flow mechanisms. The velocities of the upward flow without buffer set on the wall are much higher than that with buffer set.

Abstract:

In this research, the effect of steam on synthetic fuel production from sawdust in new-designed dual-bed gasification was studied. The dual-bed gasification reactor composed of bubbling/fast fluidized bed combustor and fixed bed gasifier (pyrolysis included) was designed to produce syngas (CO + H2 + CO2 and CH4). The results showed that syngas produced by the dual-bed gasifier with higher steam/carbon ratio also had higher H2 content. In theory, the various reactions expected to occur in the gasification process were boudouard, water-gas and water-gas shift, methanation and steam reforming. Si

Abstract:

In this paper, a dual fluidized bed has been established. The effect of bed material build-up height and gas velocity on the solid circulation rate of CFB (circulating fluidized bed) and BFB (bubble fluidized bed) has been studied. The results show that the solid circulation rate is increased with the increasing of gas velocity Uc and the bed material build-up height. Bed material build-up height of BFB and CFB is changed with the changing of gas velocity Uc. The bed material heights of CFB and BFB have been also investigated in this experiment.
