Abstract

A new chlorine-removal agent for high temperature gas was made of a cheap natural mineral and alkali compounds. The sorbent has high breakthough chlorine content of 37.2% (in the condition of 650 ℃、2 500 h^-1 space velocity and 1.8 g/m³ HCl input concentration) and high mechanical strength. Effects of main component proportion, space velocity and temperature on sorbent properties were examined. Adsorption process was found to be influenced mainly by chemical reaction from the kinetics.
- high temperature coal gas,
- chloride removal sorbent,
- breakthough chlorine content,
- kinetics
