  • Patent number: 10975006
    Abstract: Para-xylene production processes are disclosed, with such processes being integrated with extractive distillation or other separation to effectively separate, for example to remove and recover, ethylbenzene and other components that co-boil with the isomers of xylene. This allows for xylene isomerization, downstream of the separation of para-xylene from its other isomers, to be operated under milder conditions (e.g., liquid phase, absence of added hydrogen) without the need for ethylbenzene conversion. The associated decreased yields of byproducts such as light gases and non-aromatic hydrocarbons, together with the generation of purified ethylbenzene having value for styrene monomer production, can significantly improve overall process economics.

  • Patent number: 8999143
    Abstract: A process is presented for increasing the aromatics content in a reformate process stream. The process modifies existing processes to change the operation without changing the reactors or heating units. The process includes bypasses to utilize heating capacity of upstream heating units, and passes the excess capacity of the upstream heating units to downstream process streams.

  • Publication number: 20150057480
    Abstract: A system for radial flow contact of a reactant stream with catalyst particles includes a reactor vessel and a catalyst retainer in the reactor vessel. The catalyst retainer includes an inner particle retention device and an outer particle retention device. The inner particle retention device and the outer particle retention device are spaced apart to define a catalyst retaining space. The inner particle retention device defines an axial flow path of the reactor vessel, and the outer particle retention device and an inner surface of a wall of the reactor vessel define an annular flow path of the reactor vessel. The system includes an inlet nozzle having an exit opening in fluid communication with the axial flow path, and an outlet nozzle in fluid communication with the annular flow path. The system can further include a fluid displacement device in the axial flow path of the reactor vessel.

  • Patent number: 8926829
    Abstract: A process for reforming a hydrocarbon stream is presented. The process involves splitting a naphtha feedstream to at least two feedstreams and passing each feedstream to separation reformers. The reformers are operated under different conditions to utilize the differences in the reaction properties of the different hydrocarbon components. The process utilizes a common catalyst, and common downstream processes for recovering the desired aromatic compounds generated.

  • Patent number: 8926830
    Abstract: Processes for producing aromatics from a naphtha feedstream are provided. An exemplary process includes passing the feedstream to a fractionation unit, thereby generating a first stream including hydrocarbons having less than 8 carbon atoms and a second stream including hydrocarbons having at least 8 carbon atoms. The first stream is passed to a first reformer operated at a first set of reaction conditions to generate a first product stream. The first set of reaction conditions includes a first temperature and a first pressure. The second stream is passed to a second reformer operated at a second set of reaction conditions to generate a second product stream. The second set of reaction conditions includes a second temperature and a second pressure. The first pressure is lower than the second pressure.

  • Patent number: 8920633
    Abstract: High energy (e.g., ultrasonic) mixing of a liquid hydrocarbon feedstock and reactants comprised of an oxidation source, catalyst and acid yields a diesel fuel product or additive having substantially increased cetane number. Ultrasonic mixing creates cavitation, which involves the formation and violent collapse of micron-sized bubbles, which greatly increases the reactivity of the reactants. This, in turn, substantially increases the cetane number compared to reactions carried out using conventional mixing processes, such as simple mechanical stirring. Alternatively, an aqueous mixture comprising water and acid can be pretreated with an oxidation source such as ozone and subjected to ultrasonic cavitation prior to reacting the pretreated mixture with a liquid hydrocarbon feedstock.

  • Patent number: 8912110
    Abstract: One embodiment is a catalyst for catalytic reforming of naphtha. The catalyst can have a noble metal including one or more of platinum, palladium, rhodium, ruthenium, osmium, and iridium, an alkali or alkaline-earth metal, a lanthanide-series metal, and a support. Generally, an average bulk density of the catalyst is about 0.300 to about 1.00 gram per cubic centimeter. The catalyst has a platinum content of less than about 0.375 wt %, a tin content of about 0.1 to about 2 wt %, a potassium content of about 100 to about 600 wppm, and a cerium content of about 0.1 to about 1 wt %. The lanthanide-series metal can be distributed at a concentration of the lanthanide-series metal in a 100 micron surface layer of the catalyst less than two times a concentration of the lanthanide-series metal at a central core of the catalyst.
