Abstract: A field of environmental protection and discloses a method for preparing an amorphous silica-alumina encapsulated metal oxide catalyst and application thereof. The catalyst is prepared by filling silica-alumina precursors in tunnels of a monometallic or bimetallic complex and then performing heat treatment. The catalyst has the advantages that acidic sites and oxygen vacancies are highly dispersed, the pore size range is large and the mass transfer efficiency is high, improves the efficiency of a cracking-oxidation tandem reaction, and achieves full purification of carbon/nitrogen pollutants in landfill leachate. The COD removal rate of the landfill leachate reaches 98.3% or above, and the ammonia nitrogen removal rate thereof reaches 98.0% or above. The COD concentration of oxypyrolysis purified effluent is less than 98.7 mg/L and the ammonia nitrogen concentration thereof is less than 24.9 mg/L.

Abstract: A process for converting crude oil to light olefins, aromatics, or both, includes contacting a crude oil with an FCC catalyst composition in a catalytic cracking system at a temperature of greater than or equal to 580° C., a weight ratio of the FCC catalyst to the crude oil of from 2:1 to 10:1, and a residence time of from 0.1 seconds to 60 seconds. Contacting causes at least a portion of hydrocarbons in the crude oil to undergo cracking reactions to produce a cracked effluent comprising at least olefins. The FCC catalyst composition for producing olefins and aromatics from crude oil includes ultrastable Y-type zeolite impregnated with lanthanum, ZSM-5 zeolite impregnated with phosphorous, an alumina binder, colloidal silica, and a matrix material comprising Kaolin clay.

Abstract: 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.
