    Abstract: Methods are disclosed for hydrocracking processes that convert a significant portion of a heavy hydrocarbon feedstock such as vacuum gas oil (VGO) to lower molecular weight, lower boiling hydrocarbons. In addition to molecular weight reduction, the processes also substantially reduce the pour point of a recovered higher boiling fraction or unconverted oil, all or a portion of which may be used as a lube base stock, optionally after one or more further treatment steps such as hydrofinishing. The ability to reduce the pour point, through hydroisomerization, of the higher boiling fraction greatly improves the quality of this fraction, or unconverted oil, for use in lube base stock preparation.

  • Patent number: 7615142
    Abstract: An expanded bed hydroprocessing system and related method includes at least one expanded bed reactor that employs a solid catalyst to catalyze hydroprocessing reactions involving hydrogen and a high molecular weight hydrocarbon feedstock (e.g., a Fischer-Tropsch wax) that is contaminated with solid particulates. Hydroprocessing the high molecular weight hydrocarbon feedstock in an expanded bed reactor results in formation of a hydroprocessed material from the hydrocarbon feedstock, while eliminating the risk of plugging of the supported catalyst bed by the solid particulates as compared to a reactor including a stationary catalyst bed.

  • Patent number: 7381321
    Abstract: Process for transforming a gas-oil fraction that makes it possible to produce a fuel that has a quality according to stringent requirements in terms of sulfur content, aromatic compound content, cetane number, boiling point, T95, of 95% of the compounds and density, d15/4, at 15° C. This process comprises a hydrorefining stage and a hydrocracking stage, whereby the latter uses a catalyst that contains at least one zeolite. The conversion of products that have a boiling point of less than 150° C. is, throughout the two stages of hydrocracking and hydrorefining, less than 40% by weight and, for the hydrorefining stage, between 1 and 15% by weight. The temperature, TR2, of the hydrocracking stage is less than the temperature, TR1, of the hydrorefining stage, and the variation between temperatures TR1 and TR2 is between 0 and 80° C.

  • Patent number: 7151199
    Abstract: Hydrocarbon or oxygenate conversion process in which a feedstock is contacted with a non zeolitic molecular sieve which has been treated to remove most, if not all, of the halogen contained in the catalyst. The halogen may be removed by one of several methods. One method includes heating the catalyst in a low moisture environment, followed by contacting the heated catalyst with air and/or steam. Another method includes steam-treating the catalyst at a temperature from 400° C. to 1000° C. The hydrocarbon or oxygenate conversion processes include the conversion of oxygenates to olefins, the conversion of oxygenates and ammonia to alkylamines, the conversion of oxygenates and aromatic compounds to alkylated aromatic compounds, cracking and dewaxing.
