| Abstract: | A new absorptive catalyst used for removing SO_2 and NO_x from flue gas was prepared (using) lignite as a main raw material. The optimum process conditions for preparation of the absorptive catalyst are obtained. The influences of the ratio of raw material mixture, dry distillation temperature, activation temperature and activation time on the performance of the absorptive catalyst were investigated. The results show that the factors affect the performance of the absorptive catalyst from lignite. The absorptive catalyst from lignite prepared under the optimum conditions has the rotary strength of 94%96% and the iodine absorption rate of 38%54%. After modification treatment, its desulfuration efficiency is 88%96% and denitrification efficiency is (70%94%.) |
| Keywords: | lignite absorptive catalyst flue gas desulfuration denitrification |
