Removal of Hydrogen Sulphide Gas Using Agricultural Wastes

T. Wajima
Abstract—In Japan, the total generation of biomass waste is 300 million tons annually, and the shortage of the final disposal site is a problem. Therefore, new use of agricultural waste is required. A representative gas for odor damage is hydrogen sulphide gas. In this study, removal capacity of agricultural wastes for low concentration hydrogen sulphide gas was examined to use as hydrogen sulphide gas absorbent. Adsorption experiments on hydrogen sulphide gas (500 ppm) using peanut shell, rice straw, rice husk, and commercial charcoal were carried out. Experimental results showed that the adsorption amount of charcoal was 2335 mg/g, while those of agricultural wastes are very low (rice husk: 27 mg/g, peanut shell: 22 mg/g, rice straw: 18 mg/g). By pyrolyzing peanut shell, the H2S gas adsorption of peanuts shell promote with increasing pyrolysis temperature due to the high specific surface area, and its adsorption amount of the product pyrolyzed at 600 oC is about 65% of charcoal.

Index Terms—Biomass waste, H2S gas removal, pyrolysis, specific surface area.
