    摘要: A touch sensor switch that responds to touching, or even to the proximity of an object, is disclosed. The switch includes a number of capacitance elements, or touch pads, that produce an effective capacitance dependent upon the physical proximity of the object. A microcontroller under control of a program stored in a read-only memory causes its I/O port to set a transient voltage on each capacitance element as a logic level. Each transient voltage is at variance with the capacitive element's preferred voltage level. The program then reads the I/O port, and hence the logic levels of the capacitance elements, as the capacitive elements revert to their preferred voltage levels, and calculates the proximity of the object, or touching, from relationships among recorded signals. The circuit may also be embodied in an application specific integrated circuit.

    摘要: A method is provided of selecting operating parameters for an aromatization process having at least penultimate and final stages, each containing a respective catalyst, for optimum aromatic barrel per calendar day (AB/CD) production of product having a selected RON and/or over a particular run length. The catalyst lives are determined at constant LHSV for the penultimate and final stage catalysts for a given feed RON to each stage as a function of the change in RON from that of the feed to that of the C.sub.5+ effluent from the respective stage. The penultimate stage C.sub.5+ effluent RON is selected to be such that the lives of the catalysts in each stage are substantially equal. Preferably the yield of C.sub.5+ effluent from each stage and the life of the catalyst used in each stage is determined as a function of the pressure of that stage. The operating pressures of the stages are then selected to be within about 30% of that which gives the highest AB/CD.

    摘要: A naphtha feed is contacted in a penultimate reforming stage under catalytic reforming conditions with a first catalyst. The effluent from the penultimate reforming stage is contacted in a final reforming stage under catalytic reforming conditions and at substantially the same pressure as is maintained in the penultimate reforming stage with a second catalyst. The reforming pressure is selected to provide optimal OB/CD production of product reformate of a desired RON from the final stage.
