  • Patent number: 6729396
    Abstract: A coal formation may be treated using an in situ thermal process. A mixture of hydrocarbons, H2, and/or other formation fluids may be produced from the formation. Heat may be applied to the formation to raise a temperature of a portion of the formation to a pyrolysis temperature. An average temperature and/or pressure within the formation may be controlled to inhibit production of hydrocarbons that have carbon numbers greater than 25. A small amount of hydrocarbons having carbon numbers greater than 25 may be entrained in vapor produced from the formation.

  • Publication number: 20040082823
    Abstract: The present invention is directed to a method of providing enhanced molecular stability to hydrocarbons, such as the various oils, lubricants, fuel and rubbers typically used in internal combustion engines. The invention generally comprises inhibiting the liquid phase oxidation of hydrocarbons by atmospheric oxygen at elevated temperatures through the micro-addition of non-toxic of alkyl organic additives. The alkyl organic additives are anionic surface active agents (ASAAs) of the general formula R—OSO3M or R—OP3Z2, where “M” is Na or K, where “Z” is Na, K or an alkyl group containing between ten and fourteen carbons and where “R” is an alkyl group consisting of between six and sixteen carbons. The additives are generally used in quantities from 0.01 to 10 mass percent, at temperatures between 70°-170° C. and in the presence of an aromatic solvent.

  • Patent number: 6717021
    Abstract: A solvating component for a solvated mesophase pitch. The solvated component includes a mixture of aromatic hydrocarbons having boiling points in the atmospheric equivalent boiling point range of about 285° to about 500° C. (about 550° F.-932° F.). At least 80% of the carbon atoms of the hydrocarbons are aromatic as characterized by carbon 13 NMR. The aromatic hydrocarbons are selected from a group consisting of aromatic compounds having 2 to 5 aromatic rings, substituted aromatic compounds having 2 to 5 aromatic rings wherein said substituents are alkyl groups having 1 to 3 carbons, hydroaromatic compounds having 2 to 5 rings, substituted aromatic compounds having 2 to 5 rings wherein said substituents are alkyl groups having 1 to 3 carbons, and mixtures thereof.

  • Patent number: 6695965
    Abstract: A wax blending process is disclosed which retains the desirable properties of a Fischer-Tropsch wax, while adjusting the hardness of the wax to within to a desired range. The invention utilizes a synergistic effect between hard virgin Fischer-Tropsch wax and softer mildly isomerized Fischer-Tropsch wax in a blending process which allows the artisan to adjust the hardness of a wax product to within desired ranges. The process involves passing a Fischer-Tropsch wax over a hydroisomerization catalyst under predetermined conditions including relatively mild temperatures such that chemical conversions (e.g., hydrogenation and mild isomerization) take place while less than 10% boiling point conversion (hydrocracking) occurs, thus preserving overall isomerized wax yield.
