摘要:
Processes for preparing mixed metal oxide catalysts suitable for partial oxidation of alkanes, alkenes and mixtures thereof, where in the processes comprise the steps of: providing an aqueous aerosol of one or more metal oxide catalyst precursors; and irradiating the aqueous aerosol of one or more metal oxide catalyst precursors with microwave energy. Optionally, the catalyst may be further modified using one or more chemical treatments, one or more physical treatments and one or more combinations of chemical and physical treatments, to further improve catalyst performance characteristics.
摘要:
Solid acid catalysts for use in alkylation processes are described. The solid acid catalysts include a multimetallic (e.g. bimetallic, trimetallic or tetrametallic) component that performs a hydrogenating function for the reactivation (or regeneration) of the catalyst in the presence of hydrogen. The multimetalic catalyst includes a noble metal such as platinum or palladium. The invention also relates to alkylation processes using the multimetallic solid acid catalysts having a multimetallic component for hydrogenation.
摘要:
Alkenes, unsaturated saturated carboxylic acids, saturated carboxylic acids and their higher analogues are prepared cumulatively from corresponding alkanes utilizing using a hybrid catalyst system and a hybrid process which comprises steam cracking of alkanes, to corresponding alkenes in combination with one or more oxidation catalysts for catalytically converting the corresponding alkenes to further corresponding oxygenated products using short contact time reactor conditions.
