    摘要： A catalytic process is provided for isomerizing an isomerization feed containing an aromatic C.sub.8 mixture of ethylbenzene and xylene in which the para-xylene content is less than equilibrium which comprises contacting said feed, under conversion conditions, with a catalyst comprising a crystalline aluminosilicate zeolite having a crystal size of at least about 1 micron, a silica to alumina ratio of at least about 12 and a constraint index, as hereinafter defined, within the approximate range of 1 to 12 to yield an isomerization product characterized by a reduced ethylbenzene content and an enhanced para-xylene content.

    摘要： The present invention is related to a method for kinetically separating a light hydrocarbon mixture comprising at least two components by preferentially adsorbing a first component on a zeolite adsorbent comprising 8-member rings of tetrahedra as the pore opening controlling hydrocarbon diffusion and alkali metal cations balancing a framework charge, wherein a second component is not preferentially adsorbed. The novel process comprises contacting the light hydrocarbon mixture with a zeolite adsorbent having a SiO2/Al2O3 ratio greater than about 50 and less than 200 and further having a diffusion rate at least 50 times greater for the first component as compared to the second component, and then recovering at least one of the first component or the second component.

    摘要： A method of selectively adsorbing propylene in mixtures of propylene/propane and propylene/olefins through the use of zeolites having structures with a maximum of 8-member rings of tetraheda controlling the diffusion rate. Suitable zeolite adsorbents are those having the CHA and ITE structure types. Other 8-member ring zeolites, including aluminosilicates, with a Si:Al molar ratio of at least about 200 and having substantially no free acid are also suitable adsorbents.

    摘要： An electronic accessory assembly to be used with a host electronic instrument provides previously recorded data from a non-volatile memory as to the accessory's operational capabilities. This memory is accessed by a host device either when the host device is powered up, or when an new accessory is connected to the host device. The host device then uses this information along with the operational requirements of the user to set the operational parameters of the accessory/host combination to optimally perform the functions required by the user.
