| Abstract: | Various harmful waste gases are generated in the production of PAN-based carbon fibers,which contains HCN,a highly toxic substance,so the waste gases should be treated before let to the air.Several methods for removing HCN-containing exhaust gases were discussed,including absorption,adsorption,and combustion.The principle of each method was introduced in details,and the feasibility of each method was analyzed.The results showed that direct combustion method was more appropriate for industrial production due... |
