Process for the production of carbonaceous adsorption agents doped with elementary sulfur and a process for waste gas cleaning using such adsorption agents |
摘要 |
The invention concerns a process for the production of carbonaceous adsorption agents doped with elementary sulfur, in which sulfur is mixed with the adsorption agent, the mixture is heated to a temperature of between 120° C. and 150° C. and the temperature is maintained over a period of about an hour. The process is distinguished in that heating of the mixture is effected under a controlled oxygen-bearing atmosphere. The invention further concerns a process for waste gas cleaning using carbonaceous absorption agents doped with elementary sulfur. Preferably brown coal coke is used as the adsorption agent. |
