摘要:
A method for removing hydrogen sulfide from gaseous streams by contacting the gaseous stream with an absorbing solution of from 0.005 to 20 percent of a ferric ion complex, from 25.0 to 99.945 percent water, from 0.05 to 10.0 percent of a buffering agent, and from 0 to 74.945 percent of a water-soluble, organic solvent selected from the group consisting of dimethyl formamide and dimethyl sulfoxide.

摘要:
A method for treating platinum or palladium catalyzed porous ceramic burning pads of the type used in flameless gas heating and lighting devices. Certain catalytic substances such as thorium, alumina and silica-alumina, as well as combinations of these materials when combined with platinum or palladium, afford improved catalysts for porous ceramic burning pads of the type described above. Pads so treated reduce the carbon monoxide emissions from devices using these pads.
