  • Patent number: 8558049
    Abstract: A process for separating para-xylene from aromatic compounds is presented. The process introduces throughout a first step-time interval a first mixed xylene stream into a first feed input on a first adsorptive separation unit comprising multiple bed lines. The process further introduces throughout the first step-time interval a second mixed xylene stream into a second feed input on the first adsorptive separation unit. During a first portion of the first step-time interval, the process introduces material from a feed stream used during the first step-time interval into a bed line not used to deliver a stream into, or withdraw a stream from, the first adsorptive separation unit during the first step time interval. During a second portion of the first step-time interval, the process introduces material from a purification zone into the feed stream used during the first step-time interval.

  • Patent number: 8524087
    Abstract: Low metal, low water biomass-derived pyrolysis oils and methods for producing the same are provided. Metal- and water-containing biomass-derived pyrolysis oil is contacted with an acidic ion-exchange resin having sulfonic acid groups to produce a low metal, water-containing biomass-derived pyrolysis oil. The low metal, water-containing biomass-derived pyrolysis oil is removed from the spent ion-exchange resin after ion-exchange. The low metal, water-containing biomass-derived pyrolysis oil is distilled to produce a low metal, low water biomass-derived pyrolysis oil and a distillation product. The distillation product comprises one or both of an alcohol ion-exchange regenerant and an acidic ion-exchange regenerant which may be used to regenerate the spent ion-exchange resin. The regenerated acidic ion-exchange resin may be recycled. The spent alcohol and acid ion-exchange regenerants may be recovered and recycled.

  • Patent number: 8519205
    Abstract: Low water-containing biomass-derived pyrolysis oils and processes for producing them are provided. The process includes condensing pyrolysis gases including condensable pyrolysis gases and non-condensable gases to separate the condensable pyrolysis gases from the non-condensable gases, the non-condensable gases having a water content, drying the non-condensable pyrolysis gases to reduce the water content of the-non-condensable gases to form reduced-water non-condensable pyrolysis gases, and providing the reduced-water non-condensable pyrolysis gases to a pyrolysis reactor for forming the biomass-derived pyrolysis oil.

  • Publication number: 20130116495
    Abstract: The present process comprises a means for energy savings in one or more process pumps by driving the one or more pumps with a variable-speed driving means. The invention is particularly useful in the separation of an adsorbed product from a mixture of components using simulated-moving-bed adsorption associated with a large circulating stream pumped with variable-speed driving means for conservation of energy relative to the known art. The improvement is particularly applicable to a process for the separation of para-xylene from mixed C8 aromatics.

  • Patent number: 8431758
    Abstract: Processes for increasing overall aromatics and xylenes yield in an aromatics complex are provided. A C8+ aromatics stream from an aromatics-rich reformate is separated into a C8 aromatics fraction and a C9+ aromatics fraction comprising higher alkyl group-substituted C9 and C10 aromatics. The C9+ aromatics fraction is separated into a lighter boiling, higher alkyl group-substituted C9 or C9/C10 aromatics fraction and a heavier boiling, C10+ or C11+ aromatics fraction. The lighter boiling, higher alkyl group-substituted C9 or C9/C10 aromatics fraction is isomerized to convert a portion of the higher alkyl group-substituted C9 or C9/C10 aromatics therein into methyl-enriched C9 aromatics or methyl-enriched C9/C10 aromatics. The methyl-enriched C9+ aromatics stream comprising the methyl-enriched C9+ aromatics stream or the methyl-enriched C9/C10 aromatics is transalkylated with a toluene-containing stream.

  • 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.

  • Patent number: 8283509
    Abstract: The invention comprises an absorption heat pump to supply energy to a distillation process or an outside process. The streams used to effect the absorption heat pump are to be combined in any case as a feedstream to a conversion process, and energy thus is conserved by avoiding the necessity of reseparating the streams.

  • Patent number: 8198502
    Abstract: The invention is an adsorptive separation process for producing a para-xylene product from a feed stream comprising para-xylene, at least one other C8 aromatic, and a C9 aromatic. An adsorbent comprising X or Y zeolite and a desorbent comprising para-diethylbenzene (p-DEB) are used in an adsorptive separation zone to produce an extract stream comprising para-xylene, p-DEB, and the C9 aromatic and a raffinate stream comprising the at least one other C8 aromatic, the C9 aromatic, and p-DEB. The extract stream is separated in an extract distillation zone to produce a second desorbent stream comprising the C9 aromatic and p-DEB and the raffinate stream is separated in a raffinate distillation zone to produce a third desorbent stream comprising the C9 aromatic and p-DEB. At least a portion of at least one of the second desorbent stream and the third desorbent stream is further separated in a desorbent distillation zone to produce a stream comprising the C9 aromatic.

The spent ion-exchange resin is thereafter contacted with an acidic ion-exchange regenerant to recharge the acidic ion-exchange resin to produce a regenerated acidic ion-exchange resin. Metal- and water-containing biomass-derived pyrolysis oil is then contacted with the regenerated acidic ion-exchange resin to produce low metal, water-containing biomass-derived pyrolysis oil. The regenerated acidic ion-exchange resin may be recycled. The spent alcohol and acid ion-exchange regenerants may be recovered and recycled.
