(57) [Summary] [Purpose] An O / W type emulsion produced from natural bitumen and viscous hydrocarbons with low specific gravity such as residual fuel, which efficiently combusts to produce incombustible particulate matter and exhaust gas. Provided is a hydrocarbon fuel that can suppress the release of air pollutants such as sulfur oxides and can effectively prevent corrosion of combustion equipment and the like. [Structure] A hydrocarbon containing sulfur is mixed with water and an emulsifier to form an oil-in-water emulsion, and the emulsion is K +, Li + , Ca ++ , Ba ++ , Mg. ++ , Fe +++ And a water-soluble sulfur scavenging additive selected from the group consisting of a mixture thereof, and a molar ratio of the additive to sulfur in hydrocarbon is 0.050 or more, and SO 2 emission during combustion of emulsion A hydrocarbon fuel is provided having a level of 1.50 lb / MMBUT or less. |
