The tableted catalyst support is an alpha-alumina catalyst support obtained with high geometrical precision and displaying a high overall pore volume, thus allowing for impregnation with a high amount of silver, while exhibiting a surface area sufficiently large so as to provide optimal dispersion of catalytically active species, in particular metal species. The invention further provides a process for producing a tableted alpha-alumina catalyst support, which comprises i) forming a free-flowing feed mixture comprising, based on inorganic solids content, at least 50 wt.-% of a transition alumina; ii) tableting the free-flowing feed mixture to obtain a compacted body; and iii) heat treating the compacted body at a temperature of at least 1100° C., preferably at least 1300° C., more preferably at least 1400° C., in particular at least 1450° C., to obtain the tableted alpha-alumina catalyst support. The invention moreover relates to a compacted body obtained by tableting a free-flowing feed mixture which comprises, based on inorganic solids content, at least 50 wt.-% of a transition alumina having a loose bulk density of at most 600 g/L, a pore volume of at least 0.6 mL/g, as determined, and a median pore diameter of at least 15 nm. The invention moreover relates to a shaped catalyst body for producing ethylene oxide by gas-phase oxidation of ethylene, comprising at least 15 wt.-% of silver, relative to the total weight of the catalyst, deposited on the tableted alpha-alumina catalyst support. The invention moreover relates to a process for producing ethylene oxide by gas-phase oxidation of ethylene, comprising reacting ethylene and oxygen in the presence of the shaped catalyst body.

摘要： The present application relates to a catalyst carrier for use in the synthesis of dialkyl oxalates by gas-phase catalytic coupling of carbon monoxide comprising microscopic fine pores and one or more macroscopic large pores running through the catalyst carrier, wherein the ratio of the average pore diameter of each macroscopic large pore to the average diameter of the catalyst carrier is 0.2 or more. The present application also relates to a catalyst, comprising the catalyst carrier, an active component and an optional auxiliary, supported on the catalyst carrier. The catalyst according to the present invention not only catalyze effectively coupling of carbon monoxide in a gas phase to form dialkyl oxalate, but also improves heat dissipation, reduces pressure drop, reduces the amount applied of precious metal such as palladium, thereby reducing the use cost of the catalyst and production cost of dialkyl oxalate and then facilitating industrial mass production of dialkyl oxalate.

摘要： The present invention relates to a dehydrogenation catalyst in which a platinum-group metal, an assistant metal, and an alkali metal or alkaline earth metal component are supported on a carrier, wherein the molar ratio of platinum to the assistant metal is 0.5 to 1.49, and the catalyst has an acidity amount of 20 to 150 μmol KOH/g catalyst when it is titrated with KOH. The dehydrogenation catalyst according to the present invention may prevent coke formation from increasing rapidly when the hydrogen/hydrocarbon ratio in a dehydrogenation reaction is reduced, thereby increasing the productivity of the process. Accordingly, it makes it possible to operate the process under a condition in which the hydrogen/hydrocarbon ratio in a dehydrogenation reaction is reduced, thereby improving the economy of the process.

摘要： Presented is a composition useful in the catalytic dewaxing of a waxy hydrocarbon feedstock. The composition includes a mixture of ZSM-12 zeolite and titania and may further include a noble metal. The ZSM-12 zeolite preferably has a high silica-to-alumina ratio within its framework. The mixture may be dealuminated either by acid leaching using a fluorosilicate salt or by steam treating.
