    摘要： A method for the preparation of olefin polymerization catalysts that are the reaction products of the catalytic reaction of surface hydroxyls of a support with a trialkyl silane to afford hydrogen and the corresponding surface bound alkyl silyl ether and at the same time with a strong Lewis acid which support is converted to a silica bound anion that in a second step is fully converted by reaction with QM2 to the desired catalyst. Catalyst compositions are disclosed herein. Processes disclosed herein include processes for the polymerization of olefinically unsaturated monomers comprising contacting a plurality of one or more of the monomers with the catalyst.

    摘要： In a process for selectively separating 1-butene from a C4 feed stream comprising at least 1-butene, cis-2-butene and trans-2-butene, the feed stream is passed through a first bed of an adsorbent comprising a crystalline microporous material to form a substantially trans-2-butene-free effluent stream. Then, the substantially trans-2-butene-free effluent stream is passed through a second bed of an adsorbent comprising a crystalline microporous material to form a substantially 1-butene-free effluent stream, whereby the 1-butene is separated from the feed stream. The adsorbed 1-butene is then typically desorbed from the second adsorbent bed either by lowering the pressure or raising the temperature of the bed.
