    摘要: Reforming to produce aromatics from aliphatics, using a bound zeolite catalyst containing a Group VIII metal such as platinum, has been found to be extremely sensitive to water, even at water concentrations as low as 3 ppm in the feed, unless certain catalysts having a low water sensitivity index are used. The water sensitivity index (WSI) is described and methods for making catalysts with a low WSI are described. The sulfur content of the feed to the reforming/aromatics production process is preferably below 50 parts per billion. The catalyst used in the reforming process is preferably a high crush strength catalyst and is preferably prepared by steps including treating L zeolite with a binding enhancement agent prior to binding with a binder such as silica, silica/alumina or alumina.

    摘要: A method of preparing a reforming catalyst is disclosed wherein a large-pore zeolite is impregnated with an aqueous solution of platinum and the zeolite is only allowed to soak in the solution for less than three hours to form a catalyst. After the catalyst is dried, it is calcined in an atmosphere containing steam.

    摘要: A dipole hydrophone which includes a radiation target for acoustic energy and a counterbalancing mass. A first multilaminar magnetostrictive arm is connected to the radiation target at its center gravity and a second multilaminar magnetostrictive arm is similarly connected to the center of gravity of the counterbalancing mass. The lower portion of each arm is slotted to define two legs, and a permanent magnet, in conjunction with the slotted structure forms a closed magnetic path for flux. Windings for sensing a change in flux are slipped over the leg portions, yielding a high gain device. The two arms are connected by a coupling member which is compliantly suspended from a support structure.

    摘要: A catalytic reforming process comprising the catalytic conversion of hydrocarbons to aromatics, said process comprising treating a halided zeolite catalyst (hiz-cat) containing a Group VIII metal at commercial startup conditions and then reforming hydrocarbons, wherein said catalyst is prepared by washing a bound zeolite catalyst base or a bound zeolite catalyst before halide addition. A preferred hiz-cat is a non-acidic Pt K L-zeolite catalyst prepared by a process that includes the steps of preparing a calcined silica-bound K L-zeolite catalyst base; washing said bound zeolite catalyst base with a liquid comprising water; and incorporating Pt and halogen-containing compound(s) comprising chlorine and fluorine into said washed catalyst base. Ammonium chloride and ammonium fluoride are preferred halide sources.
