摘要： Methods are provided to prepare a low sulfur fuel from hydrocarbon sources, such as light tight oil and high sulfur fuel oil, often less desired by conventional refiners, who split crude into a wide range of differing products and may prefer presence of wide ranges (C3 or C5 to C20 or higher) of hydrocarbons. These fuels can be produced by separating feeds into untreated and treated streams, and then recombining them. Such fuels can also be formulated by combinations of light, middle and heavy range constituents in a selected manner as claimed. Not only low in sulfur, the fuels of this invention are also low in nitrogen and essentially metals free. Fuel use applications include on-board large marine transport vessels but also on-shore for large land based combustion gas turbines, boilers, fired heaters and transport vehicles and trains.

摘要： Embodiments of the present disclosure relate to a method and system for producing refined hydrocarbons from waste plastics. The method and system for producing refined hydrocarbons from waste plastics according to the embodiments of the present disclosure may minimize formation of an ammonium chloride salt (NH4Cl) and may prevent an adhesion phenomenon of impurity particles in a reactor in a refining process of waste plastic pyrolysis oil containing impurities including chlorine and nitrogen. In addition, the method and system for producing refined hydrocarbons according to the present disclosure may have excellent refining efficiency and may implement a long-term operation of a process because deactivation of a catalyst used in the process is prevented, and may produce refined hydrocarbons having a low content of impurities, a low content of olefins, and a high octane number from waste plastics.

摘要： Provided are an in situ bifunctional catalyst for deep desulfurization and increasing octane number of gasoline, and its preparation method and application. The bifunctional catalyst includes a modified catalyst carrier and a loaded active metal, where the modified catalyst carrier is a composite carrier prepared through mixing γ-Al2O3 and an acidic molecular sieve by a binder and calcining. When the bifunctional catalyst provided by the present application is used for hydrodesulfurization of gasolines, deep desulfurization, olefin reduction and octane number preservation can be realized simultaneously, thereby obtaining a high-quality oil product.

摘要： Methods are provided for forming supported catalyst compositions and/or corresponding intermediate catalyst products. The catalyst compositions have improved activity for hydroprocessing of distillate boiling range feeds under hydroprocessing conditions where the hydrogen partial pressure in the hydroprocessing environment is reduced or minimized. The catalyst compositions can correspond to supported CoMo catalysts. The improved activity for hydroprocessing under lower pressure conditions is unexpectedly achieved by using a plurality of treatments with organic compounds during the catalyst formation process.
