BIOLOGICAL PROCESS FOR CONVERSION OF HYDROGEN SULPHIDE

摘要

A microbiological method of desulphurizing gases is disclosed. Chemoautrotrophic bacteria of the Thiobacillus genus are used to remove sulphides from gases. More specifically, the bacteria Thiobacillus thiooxidans in a low pH, aerobic atmosphere oxidizes hydrogen sulphide to sulphur or sulphate compounds in a contacting column in which countercurrent flow of gas and aqueous medium occurs.
