    Abstract: The use of one or more alkali metals, preferably sodium, to remove sulfur from hydrocarbon streams containing up to about 100 wppm sulfur. The hydrocarbon stream is introduced into a reactor where it is contacted with one or more alkali metals. The treated hydrocarbon stream is then subjected to a water wash thereby resulting in an aqueous phase fraction and a hydrocarbon phase fraction. The aqueous phase fraction, which is separated from the hydrocarbon phase fraction contains water-soluble sodium moieties.

    Abstract: An exhaust path and a heated portion such as an air duct of an internal combustion engine are connected to each other by a heat pipe. A heat pipe working fluid (water) vaporized by the heat of the exhaust gas in a heat receiving portion of the heat pipe is condensed in a heat discharging portion of the heat pipe and heated in the heated portion by the heat of the exhaust gas. An outer cylinder is formed around the casing of the heat pipe, and the exhaust path and the heated portion are connected to each other through heat insulating members, while at the same time supporting the heat pipe body through heat insulating members.

    Abstract: Refractory or hard sulfur found in a hydrocarbon stream containing refractory sulfur heterocycle compounds, particularly those exhibiting steric hindrance, is removed from the stream by contacting it with a sodium reagent comprising a sodium component, having free sodium, supported on a solid support component. If the hydrocarbon stream contains more labile or easy sulfur, then it is treated, typically by hydrodesulfurization, to remove at least most of the labile sulfur before it is contacted with the sodium reagent. This is useful for bringing the sulfur level of middle distillate fuel streams, such as diesel and jet fuel fractions, down to a level of less than about 10 wppm, employing conventional hydrodesulfurizing catalysts and conditions.
