Document Type and Number:
Japanese Patent JP5403843
Kind Code:
B2
Abstract:
Production of a catalyst for gas phase oxidation of organic compounds to alpha ,beta -unsaturated aldehydes and/or carboxylic acids, comprises an active phase of multimetal oxide composition being produced from a particulate precursor containing oxides and/or precursors and activated by calcination. Production of a catalyst for gas phase oxidation of organic compounds to alpha ,beta -unsaturated aldehydes and/or carboxylic acids, comprises an active phase of multimetal oxide composition being produced from a particulate precursor containing oxides and/or precursors and activated by calcination. A stream of precursor is fed at constant rate through calcination zone(s), in which the maximum temperature varies with time and locally are at most 5[deg]C. Independent claims are also included for: (a) a catalyst charge containing a specified active phase; (b) the production of alpha ,beta - unsaturated aldehydes and/or carboxylic acids over this catalyst charge; and (c) a belt calciner with heatable chamber(s) and gas-permeable conveyor belt for particulate material, running through the chamber(s), in which the chamber is provided with means of gas circulation by forced convection.
