Caustic-impregnated activated carbons for removal of hydrogen sulfide
Patent
·
OSTI ID:5719259
This paper describes improvement in a process for removing hydrogen sulfide from an oxygen-containing gas stream by passing the gas stream through caustic-impregnated activated carbon, the stream containing from about 5 ppm to about 10,000 ppm by volume of hydrogen sulfide. The improvement comprises: the breakthrough capacity of the caustic-impregnated activated carbon for hydrogen sulfide is extended by the addition of ammonia to the gas stream about the time of breakthrough.
