Abstract
Two reactors containing an absorbing composition are utilized to remove hydrogen sulfide (H.sub.2 S) from a fuel being utilized as fuel for an internal combustion engine. The reactors are heated to reaction temperature with the engine exhaust gas and the engine exhaust gas is also utilized to regenerate the absorbing composition. Continuous removal of hydrogen sulfide is achieved by utilizing the absoring composition in one reactor to remove H.sub.2 S while the absorbing composition in the second reactor is regenerated. When the absorbing composition in the first reactor becomes sulfided to the extent desired, the absorbing composition in the second reactor is then utilized to remove H.sub.2 S while the absorbing composition in the first reactor is regenerated.
