Applications of microwave dielectric heating in environment-related heterogeneous gas-phase catalytic systems
TL;DR: In this paper, the application of microwave dielectric heating in a range of environment-related heterogeneous catalytic reaction systems has been reviewed, including the decomposition of hydrogen sulfide, the reduction of sulfur dioxide with methane, the reformation of methane by carbon dioxide, the hydrodesulfurization of thiophene, and the oxidative coupling of methane.

SO2 retention on CaO/activated carbon sorbents. Part I: Importance of calcium loading and dispersion
M.C. Macías-Pérez,Agustín Bueno-López,M.A. Lillo-Ródenas,C. Salinas-Martínez de Lecea,Angel Linares-Solano +4 more
TL;DR: In this article, a sample with high calcium dispersion was obtained by the complex formation method, presenting the disadvantage of the low calcium loading reached, and the molar calcium conversion results were much higher than values reported for unsupported calcium compounds.

Removal of hazardous gaseous pollutants from industrial flue gases by a novel multi-stage fluidized bed desulfurizer.
TL;DR: This paper represents the desulfurization of gas mixtures by chemical sorption of sulfur dioxide on porous granular calcium oxide particles in the reactor at ambient temperature and indicates that the removal efficiency of the sulfur dioxide was found to be 65% at high solid flow rate and lower gas velocity.
Journal ArticleDOI
Solubility of SO2 in aqueous blend of sodium citrate and sodium hydroxide
TL;DR: In this article, the solubility of SO2 in an aqueous blend of Na3Ci and NaOH as innovative absorbent was determined at partial pressures of SO 2 in inlet gas stream between 0.355kPa and 0.983kPa.
Journal ArticleDOI
Application of Gas Cyclone–Liquid Jet Absorption Separator for Flue-Gas Desulfurization
TL;DR: In this article, a gas cyclone and liquid jet absorption separator was employed to conduct a wet flue-gas desulfurization experiment on a gas mixture consisting of air in room temperature and sulfur dioxide (SO2) to explore this device's prospect of tail gas purification.

Effect of specific surface area on the reactivity of CaO with SO2
R. H. Borgwardt,Kevin R. Bruce +1 more
TL;DR: In this paper, the rate of reaction of calcined limestone (CaCO/sub 3/) with sulfur dioxide (SO/sub 2/) and oxygen (O/sub 4) at conditions that eliminate all resistances not associated with the lime (CaO) grain surface was investigated.

SO2 capture fluidised-bed boilers: re-emission of SO2 due to reduction of CaSO4
Anders Lyngfelt,Bo G Leckner +1 more
TL;DR: In this paper, a 16MW fluidized-bed boiler was studied and the authors showed that CaSO 4 is decomposed to CaO with subsequent release of SO 2 at temperatures above 880-890°C, and at an excess air ratio of 1.4.
