METHOD FOR PRODUCING CUMENE

A method for producing cumene involves subjecting cumyl alcohol to (a) hydrocracking reaction, or (b) dehydration and subsequent hydrogenation reaction, to obtain cumene. The method includes the following steps:

(A): feeding a liquid containing cumene to a reactor loaded with a catalyst,

(B): feeding hydrogen and a liquid containing cumyl alcohol to the reactor after the step (A).

Hydrophobic palladium/metal organic framework material, preparation method thereof, and application therefor for use in synthesizing 2,5-dimethylfuran
11584729 · 2023-02-21 · ·

A hydrophobic palladium/metal organic framework (MOF) material, which is a solid catalyst material obtained by taking a porous MOF as a carrier, introducing elementary palladium by means of an immersion-reduction method, and performing polydimethylsiloxane coating layer processing. A method which uses hydrophobic palladium/MOF material to selectively catalyze hexoses to prepare 2,5-dimethylfuran comprises: dissolving a hexose into an alcohol; using the hydrophobic palladium/MOF material as a catalyst and polymethylhydrosiloxane as a hydrogen donor, reacting at 70 to 130° C. for 0.25 to 12 h under the action of an acidic additive; the concentration of the hexose in the alcohol is 0.2 to 10 wt %, and the total amount of Pd contained in the hydrophobic palladium/MOF material relative to a hexose is 0.1 to 5 mol %. The hydrophobic palladium/MOF material has a stable structure, and under the same conditions, has a catalyzing efficiency which is significantly higher than that of commercially available palladium on carbon and common palladium/MOF materials.

Catalyst for automotive emissions control

An automotive catalytic converter includes a three-way catalyst having Rh as the only precious metal configured as a front zone and a three-way catalyst having a mixture of Rh and Pd, Pt, or both configured as a rear zone, such that an exhaust gas from an internal combustion engine passes through the front zone before passing through the rear zone to minimize sulfur poisoning of the catalytic converter.
