| 20110112346 | PROCESS FOR PRODUCING ADAMANTANE - A method for producing adamantane by performing an isomerization reaction in two stages using endo-tetrahydrodicyclopentadiene and/or exo-tetrahydrodicyclopentadiene as a starting material, wherein in a first-stage isomerization reaction from endo-tetrahydrodicyclopentadiene (tricyclo[5.2.1.0 | 05-12-2011 |
| 20120116137 | SINGLE LOOP MULTISTAGE FUEL PRODUCTION - Synthetic fuels are produced from synthesis gas in a four-stage reactor system with a single recycle loop providing the requisite thermal capacity to moderate the high heat release of the reactions and to provide the reactants and reaction environments for the efficient operation of the process. The first stage converts a portion of the synthesis gas to methanol, the second stage converts the methanol to dimethylether, the third stage converts the methanol and dimethylether to fuel and the fourth stage converts the high melting point component, durene, and other low volatility aromatic components such as tri- andtetra-methylbenzenes to high octane branched paraffins. The four-stage catalyst used for hydrotreating is resistant to CO poisoning. The reactions i produce water as a side product that is carried through to a high pressure separator after the fourth stage. The streams from the separator are a liquid fuel stream, a water stream and a gaseous stream that contains light hydrocarbon gases and the unreacted synthesis gas. The larger part of this gas stream is recycled to the inlet of the first stage and mixed with the fresh synthesis gas stream. Alternatively, the fresh synthetic gas stream is mixed with the product of the second stage. The smaller part of the gas stream from the separator is sent to hydrocarbon recovery and to fuel gas used for providing preheat of various streams. The liquid fuel is sent for blending into fuel products, such as gasoline, jet fuel, or diesel, and the water stream can be sent, for example, to the synthesis gas producing plant for steam generation. | 05-10-2012 |
| 20130096356 | METHODS AND APPARATUSES FOR THE ISOMERIZATION AND DEISOHEXANIZING OF HYDROCARBON FEEDS - Methods and apparatuses for the isomerization and deisohexanizing of a feed are provided. In a method for the isomerization of a feed in an isomerization zone to form an isomerized stream and the deisohexanizing of the isomerized stream in a deisohexanizer zone, heat is exchanged between the isomerization zone and the deisohexanizer zone to raise the temperature of the feed and to reduce the temperature of the deisohexanizer sidecut stream. | 04-18-2013 |
| 20140018587 | NOVEL FUEL COMPOSITION - This invention relates to fuel compositions for use in combustion engines, such as for motor vehicle and aircraft usage. The fuel composition contains at least 99.5% of aromatic hydrocarbons and paraffinic hydrocarbons. The composition also preferably contains no lead, no multi-ring compound (only single ring compounds are present), less than about 15 ppm sulfur, and/or less than about 5 ppm nitrogen species. The resulting fuel is a drop-in fuel that provides clean burning with little to no engine deposit, high lubricity, high stability, and low corrosion. | 01-16-2014 |
| 20140171706 | METHODS AND APPARATUSES FOR FORMING LOW-AROMATIC HIGH-OCTANE PRODUCT STREAMS - Methods and apparatuses for forming low-aromatic high-octane product streams and methods for processing hydrocarbons are provided. In an embodiment, a method for forming a low-aromatic high-octane product stream includes deisohexanizing or deisoheptanizing a hydrocarbon stream and forming a cycloalkane-rich stream. Further, the method includes isomerizing the cycloalkane-rich stream at equilibrium conditions favoring formation of cyclopentanes over cyclohexanes. | 06-19-2014 |
