Abstract: Methods for making a supported chromium catalyst are disclosed, and can comprise contacting a silica-coated alumina containing at least 30 wt. % silica with a chromium-containing compound in a liquid, drying, and calcining in an oxidizing atmosphere at a peak temperature of at least 650° C. to form the supported chromium catalyst. The supported chromium catalyst can contain from 0.01 to 20 wt. % chromium, and typically can have a pore volume from 0.5 to 2 mL/g and a BET surface area from 275 to 550 m2/g. The supported chromium catalyst subsequently can be used to polymerize olefins to produce, for example, ethylene-based homopolymers and copolymers having high molecular weights and broad molecular weight distributions.

Abstract: An exhaust gas purification catalyst comprises a substrate and a catalyst layer on the substrate, and has a first section upstream along a flow direction of the exhaust gas and a second section downstream from the first section. The catalyst layer in the first section comprises a first catalyst layer comprising palladium and a second catalyst layer comprising rhodium and covering the first catalyst layer. A pore volume proportion, which is a proportion of a total volume of the pores having a pore diameter of 0.06-30.0 μm as measured by mercury press-in method and existing in the substrate and the catalyst layer in the first section to a volume of a entire first section, is 12-18%. A wash coat amount, which is a mass per unit volume of the catalyst layer in the first section to the volume of the substrate existing in the first section, is 100-190 g/L.

Abstract: Methods for synthesizing a mesoporous nano-sized zeolite beta are described. The method may include mixing an aqueous base solution with hexadecyltrimethylammonium bromide (CTAB) to form a first solution; adding nano-sized zeolite particles having a particle size of less than or equal to 100 nm to the first solution to form a second solution. The nano-sized zeolite particles include a microporous framework with a plurality of micropores having diameters of less than or equal to 2 nm and a BEA framework type. The method may further include transferring the second solution to an autoclave operated at 25° C. to 200° C. for 3 to 24 hours to form a colloid; drying the colloid at 100° C. to 200° C. for 8 to 36 hours without washing the colloid to form a zeolite precursor; and calcining the zeolite precursor at 250° C. to 600° C. for 1 to 8 hours to form the mesoporous nano-sized zeolite beta.
