A one step electrolytic technique for removing hydrogen sulphide from fuel gases before combustion could make coal gasification economically feasible, according to the US developers of a ceramic membrane used in the process.
Researchers at the Georgia Institute of Technology in the USA have made an electrochemical membrane from a porous ceramic filled with a molten carbonate salt. According to the scientists, an electric current passing through the membrane induces a chemical reaction which splits the hydrogen sulphide impurities in fuel gases into sulphide ions and hydrogen.
The sulphide ions migrate to the anode of the cell where they are converted to ...
