Study on Ca-based Sorbents Sulfidation in Gasifier;

The result indicates different influence of temperature, calcination time and calcination atmosphere on sulfidation.

A bench-scale fluidized bed system was employed to investigate the effects of temperature, particle size, atmosphere and partial pressure of CO_2 on the sulfuration of Changguang limestone.

This paper has analyzed several influencing factors of the ratio of calcium to sulphur in choice of circulating fluidized bed desulfurization reactor briefly, such as the desulfurization reaction principle, flue gas's staying time, the solid recirculation ratio,flue gas components, and so on.

The function of the circulating fluidized bed desulfurization reactor was analysed and the venturi distributor, the latest technology utilized in the industry, was adopted.

The mathematics formula including the three variables of H 2S limit value,the temperature of heat point and the ratio of steam to coal gas has been obtained by the thermodynamics calculation,which fits for inverse sulphureting reaction used Co Mo catalyst in the technology of low temperature conversion.
