Abstract

There is provided a process for producing a shaped catalyst for a fixed bed oxidation reaction or a fixed bed oxidative dehydrogenation reaction, the catalyst having both of sufficient mechanical strength and catalyst performance, and the catalyst is produced by supporting a catalyst powder containing a complex metal oxide having molybdenum as an essential ingredient on an inert support by a tumbling granulation method at a relative centrifugal force of 1 to 35G.

First claim

1 . A process for producing a shaped catalyst for a fixed-bed oxidation reaction or a fixed-bed oxidative dehydrogenation reaction, comprising:
supporting a catalyst powder containing a complex metal oxide having molybdenum as an essential ingredient on an inert support by a tumbling granulation method at a relative centrifugal force of 1 to 35G.

2 . The process for producing a shaped catalyst according to claim 1 ,
wherein the complex metal oxide has a composition represented by the following formula (1):
Mo a Bi b Ni c Co d Fe f X g Y h O x   Formula (1)

wherein Mo, Bi, Ni, Co, Fe and O represents molybdenum, bismuth, nickel, cobalt, iron and oxygen, respectively; X represents at least one element selected from the group consisting of tungsten, antimony, tin, zinc, chromium, manganese, magnesium, silicon, aluminum, cerium, tellurium, boron, germanium, zirconium and titanium; Y represents at least one element selected from the group consisting of potassium, rubidium, calcium, barium, thallium and cesium; a, b, c, d, f, g, h and x represents numbers of atoms of molybdenum, bismuth, nickel, cobalt, iron, X, Y and oxygen, respectively, and a=12, b=0.1 to 7, c+d=0.5 to 20, f=0.5 to 8, g=0 to 2, h=0.005 to 2, and x=a value determined depending on oxidation states of individual elements.

3 . The process for producing a shaped catalyst according to claim 1 ,
wherein an attrition degree of the shaped catalyst to be produced is 3% by weight or less.

4 . The process for producing a shaped catalyst according to claim 1 ,
wherein the shaped catalyst to be produced is a catalyst used in a reaction of producing butadiene from n-butene by an oxidative dehydrogenation reaction.

5 . A process for producing butadiene, comprising:
oxidatively dehydrogenating n-butene into butadiene by a gas-phase contact oxidative dehydrogenation reaction in a presence of molecular oxygen using the shaped catalyst obtained by the production process according to claim 4 .

6 . The process for producing a shaped catalyst according to claim 1 ,
wherein the shaped catalyst to be produced is a catalyst used in a reaction of producing an unsaturated aldehyde and/or an unsaturated carboxylic acid from an unsaturated hydrocarbon by an oxidation reaction.

7 . A process for producing an unsaturated aldehyde and/or unsaturated carboxylic acid, comprising:
oxidizing an unsaturated hydrocarbon into a corresponding unsaturated aldehyde and/or unsaturated carboxylic acid by a gas-phase contact oxidation reaction in a presence of molecular oxygen using the shaped catalyst obtained by the production process according to claim 6 .
