Effects of ultrasound on the desulfurization performance of hot coal gas over Zn-Mn-Cu supported on semi-coke sorbent prepared by high-pressure impregnation method
High temperature ceramic filter is designed and implemented for purification of hot coal gas, and then an experimental system is build in order to test its filtration performance. The reverse-pulse-jet-cleaning is introduced in detail. Finally, field experiment has been carried out and the results show that the ceramic filter keeps a high dust control efficiency and long on-line stability.
