The possibilities of obtaining the granular sorbent using extruded method from production waste and rice husks for the sorption of toxic gases.As used lignosulfonate industrial waste, which is obtained in the processing timber.The selected optimum granulation regime in different proportions of the binder and flour rice husks.As a result of the research, a technology for obtaining granular sorbents was developed.It was found that the ratio of rice husk (RH) to binder is 3: 1, the carbonization temperature 800 0 С.A study of the microstructure of the obtained samples showed that the binder has a dense surface and has only a small number of pores of round shape, mostly of large size.Also the starting material (RH) is firmly fixed in the matrix of the binder-lignosulfonate, and the further activation of these pellets from rice husk and lignosulfonate contributed to the formation of more small pores and the development of the spongy structure of the sorbents.
