process for the removal of so2 in gas stream

摘要

Abstract: the present invention relates to a process for reducing the amount of SO2 in a stream of gas containing SO2 and CO, are in contact with the gas stream with a catalyst. Claus catalyst; hydrogenation catalyst, catalytic hydrogenation, catalyst Hydrolysis of hydrolysing catalyst. In the process according to the invention, contact with the catalyst of hydrolysis is performed hydrolysing catalyst at temperatures of less than 270 M.
