Abstract
In accordance with this invention, a method is provided for decreasing hydrogen sulfide atmosphere, over sour heavy fuel oils to a predetermined acceptable level, which comprises treating such fuel oil with an effective amount of a choline base at a temperature above the decomposition temperature of the choline base. Surprisingly, this is effective to treat sour heavy fuel oils having atmospheric hydrogen sulfide content exceeding 5,000 ppm.
