标 题 :Process of making mixed metal oxide catalysts for the production of unsaturated aldehydes from olefins

摘要:The present invention is for a process for making a catalyst for production of unsaturated aldehydes, such as methacrolein, by gas phase catalytic oxidation of olefins, such as isobutylene, said catalyst containing oxides of molybdenum, bismuth, iron, cesium, tungsten, cobalt, nickel, antimony, magnesium and zinc. The process is a two-part synthesis of the catalyst with the water insoluble components in one part and the water soluble components in the other part. The water insoluble components are co-precipitated to form an intermediate catalyst precursor of a precipitated support incorporating oxides of the metal components. The intermediate catalyst precursor is filtered and washed to remove nitrates. The intermediate catalyst precursor is slurried with the remaining water soluble components. A final catalyst precursor is formed by removing the water and incorporating the water soluble components. This two-part process reduces the amount of nitrates in the final catalyst precursor.

摘要:Alkali metal beryllo-alumino-silicates of the mordenite type form, under hydrothermal conditions (100 DEG -300 DEG C in a Carius tube), from aqueous mixtures containing the structural components SiO2, Al2O3 and BeO and alkali metal hydroxides. In beryllium-containing mordenites, ratios of SiO2 to Al2O3 of from 10:1 to 120:1 may be achieved, whereas values of only up to 10:1 are known in the pure alumino-silicates of this type. The alkali metal beryllo-alumino-silicates are accessible to ion exchange in the same way as the beryllium-free representatives. The so-called NH4- and H-forms obtaineable by ion exchange may be used for the synthesis of highly active sorption compositions or catalysts after calcination.
