Process to upgrade oil using metal oxides
InactiveUS20060016723A1Reduce acidityReduce the numberRefining with metalsLiquid organic insulatorsHydrocotyle bowlesioidesCarboxylic acid
Described herein are compositions and methods for using metal oxides to upgrade oil. Metal oxides may be used as catalysts to reduce the TAN of the oil by converting carboxylic acids such as naphthenic acids into non-corrosive products. In some cases, the conversion occurs by a decarboxylation of the carboxylic acid to produce CO2. A second process promoted by metal oxides is hydrocarbon cracking. Cracking decreases the viscosity and increases the API, and produces lower molecular-weight hydrocarbons that are useful for many fuels and lubricants. Reductions in TAN and the increases in API improve the quality of increase the value of oil.

Method for desulfurizing a fuel for use in a fuel cell power plant
A fuel processing system is operable to remove substantially all of the sulfur present in an undiluted hydrocarbon fuel stock supply 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, naphtha, light hydrocarbon fuels such as butane, propane, natural gas, or other like fuels which contain relatively high levels of organic sulfur compounds such as mercaptans, sulfides, disulfides, and the like. The undiluted hydrocarbon fuel supply is passed through a nickel desulfurizer bed wherein essentially all of the sulfur in the organic sulfur compounds react with the nickel reactant, and are converted to nickel sulfide while the desulfurized organic remnants continue through the remainder of the fuel processing system. The system does not require the addition of steam or a hydrogen source to the fuel stream prior to the desulfurizing step. The system operates at relatively low temperatures and can be used to desulfurize either a liquid or a gaseous fuel stream.

Process for the catalytic oxidation of sulfur, nitrogen and unsaturated compounds from hydrocarbon streams
A process for the catalytic oxidation of sulfur and nitrogen contaminants as well as unsaturated compounds present in a hydrocarbon fossil oil medium is described, the process comprising effecting the oxidation in the presence of at least one peroxide, at least one acid and a pulverized raw iron oxide. The process shows an improved oxidation power towards the contaminants typically present in a fossil oil medium, this deriving from the combination of the peroxyacid and the hydroxyl radical generated in the reaction medium due to the presence of an iron oxyhydroxide such as a limonite clay, which bears a particular affinity for the oil medium. The process finds use in various applications, from a feedstock for refining until the preparation of deeply desulfurized and deeply denitrified products.
