The present invention provides a process for producing a vanadium/phosphorus oxide catalyst by (i) preparing a catalyst precursor powder containing vanadium, phosphorus and an optional promoter element; (ii) converting the catalyst precursor powder into an activated catalyst by heat treatment; (iii) and compressing the activated catalyst into a desired shape to form the vanadium/phosphorus oxide catalyst. The vanadium/phosphorus oxide catalyst may be used in the production of maleic anhydride by the catalytic oxidation of hydrocarbon feed streams.
La présente invention concerne un processus permettant de produire un catalyseur d'oxyde vanadium/phosphore en (i) préparant une poudre de précurseur de catalyseur contenant du vanadium, du phosphore et un élément promoteur facultatif; (ii) convertissant la poudre de précurseur de catalyseur en un catalyseur activé par voie thermique; (iii) et comprimant le catalyseur activé dans une forme souhaitée afin de former le catalyseur d'oxyde vanadium/phosphore. Le catalyseur d'oxyde vanadium/phosphore peut être utilisé dans la production d'anhydride maléique par oxydation catalytique de flux d'alimentation en hydrocarbures.
