Title:
元素硫黄から硫化水素を生産する方法および重金属回収におけるその使用
Document Type and Number:
Japanese Patent JP3895926
Kind Code:
B2
Abstract:
A process was found for the conversion of elemental sulphur to hydrogen sulphide under ambient temperature and pressure. The biological hydrogen sulphide production process described is less expensive than both the chemical production of hydrogen sulphide and the biological hydrogen sulphide production from diluted sulphate containing waste water streams. Except for economical benefits also safety advantages exist compared to the chemical production of hydrogen sulphide, which is achieved at elevated temperature and pressure. The hydrogen sulphide produced can be used for the recovery of heavy metals.
