      In the synthesis of paraffins from water gas at 270°, using a contact mass prepared from Pb carbonate and Fe oxide, the catalyst takes up S from unpurified gas.  The contact material can be regenerated by oxidation with air.  The water gas used for the synthesis must be completely freed from S compounds.
