Abstract

A novel process for $H_2S$ gas treatment has been introduced, based on the combined action of a chemical absorption step and a biological step involving the biocatalytic activity of the bacterium Thiobacillus ferrooxidans. The aim of this study is the development of a process for $H_2S$ elimination from gas streams based on that chemical/biological method. The immobilized biomass reactor/chemical adsorption system is suitable for application of the removal of $H_2S$. A double stage reactor was used for the experimental work. The removal efficiencies of over 99% were observed in the range of inlet $H_2S$ concentration from 200 to 1,000ppm. The novel process showed the stable elimination efficiencies of over 95% under the retention time range from 20 to 40sec at the 1,000ppm of $H_2S$ inlet concentration.
