摘要： A process for isomerizing ethylbenzene into paraxylene using a zeolitic catalyst system based on MTW-type zeolite that is substantially free of mordenite. The invention obtains an improved yield of paraxylene without excess benzene production by dealkylation. The zeolitic silica-to-alumina ratio ranges from 20 to 45. Elimination of mordenite in the catalyst improves yields and integrated aromatics complex economics by reducing undesirable aromatic ring-loss reactions as well.

摘要： A process for preparing a transalkylation catalyst, the catalyst itself, and a transalkylation process for using the catalyst are herein disclosed. The catalyst comprises rhenium metal on a solid-acid support such as mordenite, which has been treated with a sulfur-based agent. Such treatment reduces the amount of methane produced by metal hydrogenolysis in a transalkylation process wherein heavy aromatics like A9+ are reacted with toluene to produce xylenes. Reduced methane production relative to total light ends gas production results in lower hydrogen consumption and lower reactor exotherms.

摘要： A liquid or partially liquid phase process for isomerizing a non-equilibrium mixture of xylenes and ethylbenzene uses a zeolitic catalyst system preferably based on zeolite beta and on pentasil-type zeolite. The invention obtains an improved yield of para-xylene from the mixture relative to prior art processes in a more economical manner. A preferred beta zeolite is a surface-modified zeolite beta resulting from acid washing of a templated native zeolite at conditions insufficient to effect bulk dealumination. A preferred pentasil zeolite is a MTW-type with a silica-to-alumina ratio between 20 and 45.

摘要： A tunable, low power clock generator employs a voltage regulator, one or current generators and a variable resistor bank that, together, produce a control voltage for trimming a VCO. The control voltage is arranged to also compensate, at least, for the variables of temperature, supply voltage and fabrication processes as they affect the VCO output frequency. The current generator is well characterized over the variables discussed and the resistor bank is a flexible series/parallel array of resistors made from differing materials exhibiting different temperature coefficients. The resistor bank provides for various overlapping resistance values simultaneously with various overlapping temperature coefficients wherein the temperature coefficient profile of the clock generator over frequency and temperature is controlled.
