Abstract: In the refining of crude oil, vacuum gas oil hydrotreaters and hydrocrackers are used to remove impurities such as sulfur, nitrogen, and metals from the crude oil. Typically, the middle distillate boiling material (boiling in the range from 250° F.-735° F.) from VGO hydrotreating or moderate severity hydrocrackers does not meet the smoke point, the cetane number or the aromatic specification. In most cases, this middle distillate is separately upgraded by a middle distillate hydrotreater or, alternatively, the middle distillate is blended into the general fuel oil pool or used as home heating oil. With this invention, the middle distillate is hydrotreated in the same high pressure loop as the vacuum gas oil hydrotreating reactor or the moderate severity hydrocracking reactor.

Abstract: A novel process for forming hydrocarbon waxes from synthesis gas is disclosed. This invention teaches a process whereby a Fischer-Tropsch wax can be formulated such that the wax softness as defined by ASTM Standard Test Method for Needle Penetration of waxes (ASTM D-1321) can be adjusted to within a region most preferred for end use applications while simultaneously removing undesirable impurities, such as oxygenates (e.g., primary alcohols), olefins, and trace levels of aromatics. In a Fischer-Tropsch reactor, Fischer-Tropsch wax is formed from synthesis gas in a catalyzed reaction. The Fischer Tropsch wax is then subjected to a relatively mild hydroprocessing over a hydroisomerization catalyst under conditions such that essentially no boiling point conversion is obtained, but yet chemical conversions (e.g., hydrogenation and mild isomerization) occur yielding a high purity, hydrocarbon wax product of reduced hardness.

Abstract: A fuel processing method is operable to remove substantially all of the sulfur present in an undiluted hydrocarbon fuel stock supply which is used to power a fuel cell power plant in a mobile environment, such as an automobile, bus, truck, boat, or the like; or in a stationary environment. The power plant hydrogen fuel source can be gasoline, diesel fuel, or other like fuels which contain relatively high levels of organic sulfur compounds such as mercaptans, sulfides, disulfides, thiophenes and the like. The undiluted hydrocarbon fuel supply is passed through a nickel reactant desulfurizer bed wherein essentially all of the sulfur in the organic sulfur compounds reacts with the nickel reactant, and is converted to nickel sulfide, while the now desulfurized hydrocarbon fuel supply continues through the remainder of the fuel processing system. The method involves adding hydrogen to the fuel stream prior to the desulfurizing step. The method can be used to desulfurize either a liquid or a gaseous fuel stream.
