A method of preparing a catalyst comprising a) contacting a titanium-containing compound, a solvating agent, and a solvent to form a solution; b) contacting the solution with a chrominated silica-support to form a pre-catalyst; and c) thermally treating the pre-catalyst by heating to a temperature of from about 400 C. to about 1000 C. for a time period of from about 1 minute to about 24 hours to form the catalyst.

A method is disclosed for removing ozone from a gas. According to this method, the gas is contacted with an adsorbent that includes a transition metal oxide or metal organic framework to form a treated gas. The treated gas is contacted with a noble metal catalyst to catalytically decompose ozone in the treated gas, thereby forming an ozone-depleted treated gas.

Supported chromium catalysts with an average valence less than +6 and having a hydrocarbon-containing or halogenated hydrocarbon-containing ligand attached to at least one bonding site on the chromium are disclosed, as well as ethylene-based polymers with terminal alkane, aromatic, or halogenated hydrocarbon chain ends. Another ethylene polymer characterized by at least 2 wt. % of the polymer having a molecular weight greater than 1,000,000 g/mol and at least 1.5 wt. % of the polymer having a molecular weight less than 1000 g/mol is provided, as well as an ethylene homopolymer with at least 3.5 methyl short chain branches and less than 0.6 butyl short chain branches per 1000 total carbon atoms.

Disclosed is a catalyst for producing an olefin including an oxygen carrier material and a dehydrogenation catalyst. The catalyst allows hydrogen to be converted into water by using oxygen inside the lattice of an oxide catalyst without the additional supply of oxygen, and thus, the conversion can be increased while the decrease in selectivity, which is a disadvantage of an additional oxidative dehydrogenation reaction (ODHP), is suppressed.

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.
