摘要： An isomerization catalyst is provided, along with corresponding systems and methods, which provides improved isomerization for bio-derived feeds in reaction environments where by-products from deoxygenation are present. The catalyst provides unexpectedly increased activity and/or selectivity in situations where, for example, a deoxygenation effluent is cascaded to the isomerization catalyst. Additionally, the isomerization catalyst can assist with reducing or minimizing hydrogen consumption during isomerization. The increased activity, stability, and/or reduced hydrogen consumption is achieved in part based on using a dispersion agent when adding base metals to the catalyst. In addition to the base metals, the catalyst includes a zeolitic framework structure suitable for isomerization.

摘要： Supported catalysts contain a transition metal compound impregnated on or bound to a solid support, and the transition metal is iron, cobalt, or manganese. The solid support is an inorganic solid oxide or a chemically-treated solid oxide. The transition metal compound is prepared by reacting a transition metal halide containing a ligand with an alkylating agent in a suitable reaction medium at a temperature of −70 to 15° C., prior to impregnating onto the solid support.

摘要： Methods for synthesizing a water-soluble titanium-silicon complex are disclosed herein. The titanium-silicon complex can be utilized to produce titanated solid oxide supports and titanated chromium supported catalysts. The titanated chromium supported catalysts subsequently can be used to polymerize olefins to produce, for example, ethylene based homopolymer and copolymers.
