Desulfurization performance of fly ash and CaCO3 …
The desulfurization performance of fly ash and CaCO 3 compound absorbent is experimentally investigated in a bubbling desulfurization reactor. Results show that the desulfurization rate of CaCO 3 is improved by adding fly ash at Ca/S mole ratio of 1.024. The maximum desulfurization rate of the compound absorbent could reach 94%.

Adsorptive desulfurization through charge-transfer …
Though absorbents A and C showed similar desulfurization activities after 72 h, the absorbent C is most preferred for the adsorptive desulfurization process as it needs the shorter equilibrium time. The most suitable adsorbent for industrial applications is the one that possess a shortest contact time (shortest equilibrium time).
Semi-Dry Flue Gas Desulfurization - Hamon
Features Desulphurisation efficiency above 99% can be achieved Complete SO3 separation Separation of heavy metals, dioxins and furanes Low water requirement No preliminary dust removal required Availability of over 98% can be achieved Small space requirement Low investment and operating costs Unlimited part load operation No need for special anti-corrosion measures
Desulfurization of Biomass Syngas Using ZnO …
Dry-bed adsorptive desulfurization of biomass-based syngas with low to medium sulfur content using ZnO was investigated as an alternative to the conventional wet scrubbing processes. The technical feasibility of ZnO-based desulfurization was studied in laboratory-scale H2S breakthrough experiments. The experiments were set up to utilize realistic H2S concentrations from gasification and ...

Desulfurization of H2S using cobalt-containing …
Fig. 2 shows desulfurization performances of various absorbents flowing H 2 S. The normalized concentration represents the ratio of H 2 S concentration at the outlet to that of the inlet feed. Thus, the normalized concentration indicates the removal efficiency and the normalized time corresponds to the fractional conversion of cobalt oxide to the sulfide form of Co 9 S 8 .
Desulfurization behavior of Ca-based absorbents …
The capture of H 2 S or SO 2 with Ca-based absorbents, limestone and dolomite, was investigated under a periodically changing condition between reducing and oxidizing atmospheres, taking account of the coexistence of these atmospheres in a fluidized-bed coal gasifier. The degree of desulfurization in the reducing atmosphere was large compared with that in the oxidizing atmosphere.

New nanostructured sorbents for desulfurization of …
30-1-2014 · Desulfurization of natural gas is achieved commercially by absorption with liquid amine solutions. Adsorption technology could potentially replace the solvent extraction process, particularly for the emerging shale gas wells with production rates that are generally lower than that from the large conventional reservoirs, if a superior adsorbent (sorbent) is developed.

Adsorbents - BASF Catalysts
Adsorbents are used usually in the form of spherical pellets, rods, moldings, or monoliths with hydrodynamic diameters between 0.5 and 10 mm. They must have high abrasion resistance, high thermal stability and small pore diameters, which results in higher exposed surface area and hence high surface capacity for adsorption.

desulfurization systems work with dry powder absorbent which reacts with the flue gas. Many studies have shown that when siliceous materials such as coal fly ash is mixed with calcium hydroxide (Ca(OH)2) or calcium oxide (CaO) in a hydration process, absorbents with high SO2 capture capacity could be …
