Biomass calcium looping gasification (CLG) for CO2 capture and H2 production is rather attractive but still needs developing low-cost CaO-based sorbent with enhanced mechanical strength, cyclic CO2 absorption reactivity, and multi-cycle gasification performance. In this work, cement-modified carbide slag was developed as …
The slag mobility is a key factor influencing the slag tapping process during the slagging gasification of biomass. However, the viscosity model suitable for the biomass slag (relevant to the SiO 2-CaO-K 2 O system) has not been reported yet. This study firstly proposed an Arrhenius-type viscosity model based on the bond distribution in biomass slag.

High-carbon products are obtained from waste coal gasification fine slag. The ash content of spiral tailings product is up to 90%. The spiral concentrate has a high surface area 232 m 2 /g and a high porosity. The carbon content of concentrate can be enhanced into 80% by screening. Coal gasification is one of the most promising clean …
The coal gasification slag is divided into coal gasification coarse slag and CGFS (see Fig. 1) [6]. The CGFS in the two has a large loss of ignition, high water content, and difficult resource utilization. Moreover, the carbon content is generally over 30 % [7]. At present, there is a deficiency of highly effective methods to address CGFS ...
Specifically, all impurities in gasification slag formed high-ash products in the underflow of the cyclone, and the overflow was differentiated by the cyclone into high-charcoal and charcoal-rich products respectively, facilitating the subsequent utilization of coal gasification fine slag (CGFS). Nonetheless, this method has poor separation ...
On average, conventional waste-to-energy plants that use mass-burn incineration can convert one ton of MSW to about 550 kilowatt-hours of electricity. With gasification technology, one ton of MSW can be used to produce up to 1,000 kilowatt-hours of electricity, a much more efficient and cleaner way to utilize this source of energy.

Gasification is an indirect combustion of solid and liquid biomass by converting them to combustive syngas. Gasification is an alternative process for the traditional combustion, in which the emission of dust and toxic gases can be minimized. In this chapter, a comparison of these two biomass-to-heat conversion processes applied …
Gasification slag is a solid waste generated by the coal chemical industry which has emerged in recent years. In this paper, the effect of coal gasification slag (CGS) powder content on the reaction kinetics, gel structure and the compressive strength of Portland cement was investigated for the potential application of CGS powders in …
In this paper, the production, composition, morphology, particle size structure and water holding characteristics of coal gasification slag are introduced, and the …
KEYWORDS: Coal Gasification Wastes, IGCC Fly ash, IGCC Slag, Lightweight aggregates. INTRODUCTION . The Integrated Gasification in Combined Cycle (IGCC) power plant of ELCOGAS S.A. in Puertollano, Ciudad Real, (Spain) is the first IGCC power plant implanted in Spain and the second one in Europe as result of an European …
Slaked lime powder (96 wt%) mixed with activated carbon (4 wt%) was used for the flue gas treatment system to remove acid gases, heavy metals, and polychlorinated hydrocarbons such as dioxins/furans. Slag, the main by-product of the slagging gasification process, was produced by quenching the liquified ashes in a water bath.
In order to investigate the adsorption performance of coal gasification slag, 0.2 g of coal gasification slag were added into 60.0 mL (40.0 mg/L) RhB or Cr (VI) solution. It can be seen from Figure 2 a that the adsorption of Cr (VI) by coal gasification slag can reach a dynamic equilibrium after approximately 10 min. In this study, the removal ...
Gasification furnace slag is a substrate that can be used effectively in plant ecological restoration projects. Using this substrate can contribute to sustainable development in the ecological environment construction. This study used a gasification furnace slag sample as the matrix material of functional soil based on an evaporation …
Research has found that carbide slag can promote H 2 production during coal gasification [36, 37] and biomass pyrolysis [38], but the role of carbide slag on biomass gasification under fluidizing ...
The structure characteristics and gasification activity of residual carbon from entrained-flow coal gasification slag were mainly investigated using a pore structure analyzer, a scanning electron microscopy, a Raman spectroscopy and a thermo-gravimetric analyzer. Simultaneously, a kind of residual carbon from coal chars was used for a …
