The results of the study indicate that the adoption of an enhanced Ca/S ratio, a reduced ΔT, a layered water spray and pressurized slaked sorbent can be conducive to increasing the desulfurization efficiency.

Study on the process parameters for production of H_2S by use of calcium sulfide as a raw material;

The catalytic reduction of flue gas desulfurization (FGD) gypsum to calcium sulfide over Ni Fe composite catalyst was investigated.

KINETICS AND MODEL OF OXIDATION OF CaS UNDER PRESSURE;

An optical transition additive used in farmfilmwas synthesized by doping the Cu and Eu activators into an inorganic fluorescent material,CaS with the high-temperature solid phase reduction method under unˉprotected atmosphere.

In allusion to the problems which is well known that the desulfurization rate is difficult to promote and traditional desulfuration production CaSO4 is easy to decompose during coal combustion at high temperature in furnaces, the fundamental experiments and theories research of high-temperature Stable Phase desulfurization were developed systematically.

Introduce an experiment of preparing hepatic gas, using kiln gas and crude calcium sulfide produced by calcinating calcium sulfate.

Anew method to analyse calcium polysulfides in lime sulfide by using sodium sulfite was reported in this pa-per.
