  • Patent number: 10423696
    Abstract: Techniques facilitate intelligent message processing of messages. With regard to a message, an intelligent message processor component (IMPC) can intelligently identify a desired file folder and archive the message in the folder in response to as little as one user interface (UI) control manipulation (e.g., click), when the intelligent message processor UI (IMPUI) is activated. When the IMPUI is activated, the IMPC automatically parses the message and identifies, or allows the user to identify, a keyword/phrase in the message. The IMPC automatically identifies the desired folder based on the identified keyword/phrase, and the user can click on the identified keyword/phrase to store the message in the identified file folder. The IMPUI also can comprise other UI controls that can, e.g., forward a message to another user, archive the message or related attachment in a remote storage destination, perform a customized message process, etc.

  • Patent number: 10307733
    Abstract: The present disclosure relates to a material preferably used in a guard bed, and having an increased capacity to adsorb catalyst poisons, as measured by collidine update at 200° C. The material is made by a method in which it is treated by being dried with a drying gas, preferably, at a temperature greater than about 200° C. The treated material may be used to remove impurities from untreated feed streams to, for example, aromatic alkylation and transalkylation processes, where such impurities act as catalyst poisons that cause deactivation of the acidic molecular sieve-based catalysts used, thereby increasing the cycle length of such catalysts.

    Abstract: The production of linear alkylbenzene from a natural oil is provided. A method comprises the step of deoxygenating the natural oils to form a stream comprising paraffins. The paraffins are dehydrogenated to provide mono-olefins. Then, benzene is alkylated with the mono-olefins under alkylation conditions to provide an alkylation effluent comprising alkylbenzenes and benzene. Thereafter, the alkylbenzenes are isolated to provide the alkylbenzene product.

  • Patent number: 8940950
    Abstract: The process relates to the use of any naphtha-range stream containing a portion of C8+ aromatics combined with benzene, toluene, and other non-aromatics in the same boiling range to produce toluene. By feeding the A8+ containing stream to a dealkylation/transalkylation/cracking reactor to increase the concentration of toluene in the stream, a more suitable feedstock for the methylation reaction can be produced. This stream can be obtained from a variety of sources, including the pygas stream from a steam cracker, “cat naphtha” from a fluid catalytic cracker, or the heavier portion of reformate.

  • Patent number: 8937205
    Abstract: A hydrocarbon upgrading process is described in which a hydrocarbon feed is treated in at least one of a steam cracker, catalytic cracker, coker, hydrocracker, and reformer under suitable conditions to produce a first stream comprising aliphatic and aromatic hydrocarbons. A second stream comprising C6-C9 aliphatic and aromatic hydrocarbons is recovered from the first stream and aliphatic hydrocarbons are removed from at least part of the second stream to produce an aliphatic hydrocarbon-depleted stream. The aliphatic hydrocarbon-depleted stream is then dealkylated and/or transalkylated and/or cracked (D/T/C) by contact with a catalyst under suitable reaction conditions to produce a third stream having an increased benzene and/or toluene content compared with said aliphatic hydrocarbon-depleted stream and a light paraffin by-product. Benzene and/or toluene from the third stream is then methylated with a methylating agent to produce a xylene-enriched stream.

  • Patent number: 8937206
    Abstract: The process converts FCC olefins to heavier compounds. The heavier compounds are more easily separated from the unconverted paraffins. The heavier compounds can be recycled to an FCC unit or delivered to a separate FCC unit. Suitable conversion zones are oligomerization and aromatic alkylation zones.

  • Patent number: 8921633
    Abstract: In a hydrocarbon upgrading process, a hydrocarbon feed is treated in at least one of a steam cracker, catalytic cracker, coker, hydrocracker, and reformer under suitable conditions to produce a first stream comprising olefinic and aromatic hydrocarbons. A second stream composed mainly of C4 to C12+ olefinic and aromatic hydrocarbons is recovered from the first stream and blended said second stream with a residual fraction from a steam cracker or an atmospheric or vacuum distillation unit to produce a third stream. The third stream is then catalytically pyrolyzed in a reactor under conditions effective to produce a fourth stream having an increased benzene and/or toluene content compared with said second stream and a C3-olefin by-product. The C3-olefin by-product is recovered and benzene and/or toluene are recovered from the fourth stream.

  • Publication number: 20140378722
    Abstract: The process of producing an alkylbenzene compound from the alkylation of an aromatic compound with an acyclic monoolefin is an exothermic process. A process for maintaining a relatively constant temperature improves the process and allows for controlling the yields. The process includes recycling a compound through the reactor that is relatively inert, but will moderate the exotherm, while maintaining the 2-phenyl content of the final alkylbenzene product.

  • Patent number: 8916739
    Abstract: Methods and apparatuses for preparing normal paraffins and hydrocarbon product streams are provided herein. A method of preparing normal paraffins includes providing an unsaturated feed that includes an unsaturated compound that has at least one alkenyl group. The unsaturated feed is epoxidized to convert the at least one alkenyl group in the unsaturated compound to an epoxide functional group, thereby converting the unsaturated compound to an epoxide compound that has at least one epoxide functional group. The at least one epoxide functional group in the epoxide compound is converted to at least one secondary hydroxyl functional group, thereby converting the epoxide compound to a hydroxyl-functional compound that has at least one hydroxyl functional group. The hydroxyl-functional compound is deoxygenated to form normal paraffins.

  • Patent number: 8877996
    Abstract: Disclosed is a process for the production of alkylated aromatics by contacting a feed stream comprising an alkylatable aromatic, an alkylating agent and trace amounts of water and impurities in the presence of a first catalyst and an alkylation catalyst wherein such water and impurities are removed in order to improve the cycle length of such alkylation catalysts. Water and at least a portion of impurities are removed in a dehydration zone. A reaction zone having a first catalyst which, in some embodiments is a large pore molecular sieve, acts to remove another portion of impurities, such as nitrogenous and other species. An alkylation zone having an alkylation catalyst which, in some embodiments is a medium pore molecular sieve or a MCM-22 family material, acts to remove additional impurities, and to alkylate the alkylatable aromatic compound.
