Isomerization Patents (Class 585/253)
  • Patent number: 9714392
    Abstract: Deep desulfurization of hydrocarbon feeds containing undesired organosulfur compounds to produce a hydrocarbon product having low levels of sulfur, i.e., 15 ppmw or less of sulfur, is achieved by first subjecting the entire feed to an extraction zone to separate an aromatic-rich fraction containing a substantial amount of the aromatic refractory and sterically hindered sulfur-containing compounds and an aromatic-lean fraction containing a substantial amount of the labile sulfur-containing compounds. The aromatic-rich fraction is contacted with isomerization catalyst, and the isomerized aromatic-rich fraction and the aromatic-lean fraction are combined and contacted with a hydrotreating catalyst in a hydrodesulfurization reaction zone operating under mild conditions to reduce the quantity of organosulfur compounds to an ultra-low level.

  • Patent number: 9012710
    Abstract: Fuel compositions containing an isomerized component of a single carbon number may contain at least 97 wt. %, based on the total weight of the fuel composition, of an isomerized component consisting of aliphatic paraffin isomers all having the formula CnH2n+2, where 10?n?22 and n has the same value for each aliphatic paraffin isomer in the isomerized component. The fuel compositions have a normal alkane content of less than 10 wt. %, based on the total weight of the fuel composition. Methods for preparing the fuel compositions include hydroisomerizing a normal alkane starting material to form an isomerized mixture and subsequently removing remnant normal alkanes from the isomerized mixture by solvent dewaxing and/or distillation. Some of the fuel compositions may have freezing points at or below ?47° C., making them amenable for use a surrogate fuels in the place of JP-8.

    Abstract: The present invention relates to a process for hydrocarbon conversion in the presence of an acidic ionic liquid. The hydrocarbon conversion is preferably an isomerization, especially an isomerization of methylcyclopentane (MOP) to cyclohexane.

The cyclohexane obtained in the hydrogenation and/or isomerization is preferably isolated from the process. In a preferred embodiment of the present invention, the hydrogenation is followed and the hydrocarbon conversion, especially the isomerization, is preceded by distillative removal of low boilers, especially C5-C6-alkanes such as cyclopentane or isohexanes, from the hydrocarbon mixture used for hydrocarbon conversion.

Depending on the type and amount of the aromatics remaining in the hydrocarbon mixture (HM1), especially in the case that benzene is present, the isomerization may additionally be preceded by performance of a hydrogenation of (HM1). In addition, depending on the presence of other components of (HM1), further purification steps may optionally be performed prior to or after the isomerization or hydrogenation.

    Abstract: The present invention relates to a process for preparing cyclohexane from methylcyclopentane (MCP) and benzene. In the context of the present invention, MCP and benzene are constituents of a hydrocarbon mixture (HM1) additionally comprising dimethylpentanes (DMP), possibly cyclohexane and at least one compound (low boiler) selected from acyclic C5-C6-alkanes and cyclopentane. First of all, benzene is converted in a hydrogenation step to cyclohexane, while MCP is isomerized in the presence of a catalyst, preferably of an acidic ionic liquid, to cyclohexane. The hydrogenation is preceded by a prior removal of the dimethylpentanes (DMP), with initial removal of any cyclohexane present in the hydrocarbon mixture (HM1) together with DMP. This cyclohexane already present can be separated again from DMP in a downstream rectification step and recycled into the process for cyclohexane preparation.

In the method, a lubricating base oil with a low pour point, a low cloud point and a high viscosity index is produced by a hydrorefining-isomerization/asymmetrical cracking-hydrofinishing in the presence of hydrogen, wherein a highly waxy heavy fraction oil having an initial boiling point of 300° C. to 460° C., a wax content of 5% or more, a pour point of ?20° C. or more and a cloud point of ?5° C. or more is used as a raw material, and naphtha and middle fraction oil being co-produced. The method is characterized mainly in the high yield of heavy base oil, a low pour point and cloud point, a high viscosity and viscosity index of the base oil.

  • Publication number: 20130158314
    Abstract: Systems and methods are provided for hydroprocessing a petroleum fraction, such as a bottoms fraction from a fuels hydrocracking process, to generate a lubricant base oil. A fuels hydrocracking process typically has less stringent requirements for the sulfur and nitrogen content of a feed as compared to a lubricant base oil. Additionally, depending on the nature of the feed for the fuels hydrocracking process, the bottoms fraction may contain a relatively high level of aromatics compounds. The aromatic content of such a petroleum fraction can be reduced using a aromatic saturation stage with multiple catalyst beds, or alternatively using a reactor (or reactors) with multiple aromatic saturation stages. The catalysts in the various beds or stages can be selected to provide different types of aromatic saturation activity. An initial bed or stage can provide activity for saturation of 1-ring aromatics in the petroleum fraction.

  • Patent number: 8450544
    Abstract: A method for preparing the low carbon number petrochemical products along with the high energy fuels from pyrolysis gasoline is provided. In this method, the pyrolysis gasoline is used as feedstock, and the reactive non-aromatic, unsaturated moieties, and the sulfur impurity contained in the pyrolysis gasoline are removed. Then the stabilized feedstock is used to produce C5 olefins, C6-C9 aromatic hydrocarbons as petrochemical products, and C10+ hydrocarbons as precursors of high energy fuels. Upon acid catalytic isomerization, or upon crystallization followed by acid catalytic isomerization, the C10+ hydrocarbons as precursors of high energy fuels are converted to exo-isomers as high energy fuels.

  • Publication number: 20130030231
    Abstract: The present invention relates to a bifunctional catalyst for a hydrodewaxing process with improved isomerization selectivity, and to a method for manufacturing the same, and more particularly to a bifunctional catalyst and to a method for manufacturing same, which is characterized in that EU-2 zeolite with a controlled degree of phase transformation is used as a catalyst support having an acid site. The EU-2 zeolite, the degree of phase transformation of which is controlled, includes, by controlling synthesis parameters of EU-2, predetermined amounts of materials that are phase-transformed from EU-2 crystals such as cristobalite and quartz. The metal loaded bifunctional catalyst according to the present invention improves selectivity of the isomerization process, rather than a cracking reaction, during a hydroisomerization reaction of n-hexadecane. Therefore, the bifunctional catalyst can be widely used as a catalyst for a dewaxing process such as lubricant base oil and diesel oil.

  • Publication number: 20130012746
    Abstract: A process has been developed for producing fuel from renewable feedstocks such as plant and animal oils and greases. The process involves treating a first portion of a renewable feedstock by hydrogenating and deoxygenating in a first reaction zone and a second portion of a renewable feedstock by hydrogenating and deoxygenating in a second reaction zone to provide a diesel boiling point range fuel hydrocarbon product. If desired, the hydrocarbon product can be isomerized to improve cold flow properties. A portion of the hydrocarbon product is recycled to the first reaction zone to increase the hydrogen solubility of the reaction mixture.
