    摘要: A process for reforming wherein ethylbenzene formed during the reforming is converted to xylenes. The process is carried out by reforming a feed containing precursors of ethylbenzene with a reforming catalyst under conditions effective to reform said feed; wherein the reforming catalyst is contained in a reactor which contains a second catalyst effective under said conditions to convert ethylbenzene to xylenes. The resulting product contains reduced amounts of ethylbenzene and increased amounts of xylenes.

    摘要: A process for reforming a hydrocarbon feed containing precursors of ethylbenzene, e.g., C8 isoalkane and/or C8 isoalkene precursors of ethylbenzene, that results in the formation of reduced amounts of ethylbenzene. The process is carried out in a catalytic reforming unit comprised of a plurality of operatively connected reactors comprising at least one lead reforming reactor and a tail reforming reactor. The process is carried out by reforming the feed in at least one lead reactor which contains a first reforming catalyst and a catalyst effective for converting ethylbenzene and further reforming the product of the lead reactor in the tail reactor that contains a second reforming catalyst.

    摘要: In a process for converting methane to alkylated aromatic hydrocarbons, a feed containing methane is contacted with a dehydrocyclization catalyst under conditions effective to convert said methane to aromatic hydrocarbons and produce a first effluent stream comprising aromatic hydrocarbons and hydrogen. At least a portion of said aromatic hydrocarbon from said first effluent stream is then contacted with an alkylating agent under conditions effective to alkylate said aromatic hydrocarbon and produce an alkylated aromatic hydrocarbon having more alkyl side chains than said aromatic hydrocarbon prior to the alkylating.

    摘要: A lubrication dispensing apparatus for lubricating a device with moving parts includes a lubricant reservoir, a lubricant dispenser for dispensing lubricant from the lubricant reservoir, an ultrasonic detection module which detects the amplitude of ultrasonic energy emitted by said device when its parts are moving and produces an signal related thereto, and a control module which analyzes the amplitude of the signal from the ultrasonic detection module and, in response to a lubricate signal, causes the lubricant dispenser to automatically dispense lubricant onto the moving parts of the device until the signal from the ultrasonic detector indicates that the ultrasonic energy produced by the device has decreased to a particular level. The control module includes a programmed processor and a storage memory. The memory stores as a base value the value of the detected amplitude of ultrasonic energy when the device is operating properly. After receiving a signal to lubricate the device, the processor causes the dispenser to start the flow of lubricant to the device, compares the signal from the ultrasonic detection module when the parts are moving to the base value, and causes the dispenser to cease the flow of lubricant when the signal substantially decreases.
