Abstract
Official abstract text for this publication.
The present invention relates to a method for producing an unsaturated carboxylic acid using a catalyst having both a high catalytic performance and a high mechanical strength, and in the method, a supported catalyst obtained by feeding a liquid binder component and a catalytic active component containing molybdenum and vanadium and/or a precursor thereof into a rolling granulator and conducting granulation at a relative centrifugal acceleration of 0.5 G or more and 30 G or less is used.
First claim
Opening claim text (preview).
1 - 6 . (canceled) 7 . A method for producing an unsaturated carboxylic acid, comprising: using a supported catalyst obtained by feeding a liquid binder component and a catalytic active component containing molybdenum and vanadium and/or a precursor thereof into a rolling granulator and conducting granulation at a relative centrifugal acceleration of 0.5 G or more and 30 G or less. 8 . The method for producing an unsaturated carboxylic acid according to claim 7 , wherein the catalytic active component and/or the precursor thereof of the supported catalyst contains molybdenum, vanadium and copper. 9 . The method for producing an unsaturated carboxylic acid according to claim 7 , wherein the catalytic active component and/or the precursor thereof of the supported catalyst contains molybdenum, vanadium and phosphorus. 10 . A supported catalyst, which is obtained by feeding a liquid binder component and a catalytic active component containing molybdenum and vanadium and/or a precursor thereof into a rolling granulator and conducting granulation at a relative centrifugal acceleration of 0.5 G or more and 30 G or less. 11 . The supported catalyst according to claim 10 , wherein the catalytic active component and/or the precursor thereof contains molybdenum, vanadium and copper. 12 . The supported catalyst according to claim 10 , wherein the catalytic active component and/or the precursor thereof contains molybdenum, vanadium and phosphorus.
