Development and Production of Granular Carbon Sorbents for Sorption of Toxic Gases

Abstract

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 Asa 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 the carbonization temperature 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
