Abstract
There is disclosed a production process for a catalyst which process makes it possible to efficiently carry out the supporting of a catalytic component onto a carrier and to obtain the catalyst excellent in quality and performance. This production process is a production process for the catalyst including a particulate lump carrier and a catalytic component supported thereon; with the production process comprising the step of carrying out simultaneous revolution and rocking of a treatment container 20 as charged with the carrier and a catalyst precursor including the catalytic component, thereby supporting the catalytic component onto the carrier.
Claims2
A process of producing a catalyst, the catalyst including a particulate lump carrier and a catalytic component supported thereon, the process comprising the step of:
- carrying out simultaneous revolving and rocking of a treatment container charged with a particulate lump carrier and a catalyst precursor including a catalytic component, such that said catalytic component becomes to be supported on said particulate lump carrier, wherein:
- a) the treatment container is the shape of a cylinder having a length of 1 to 3 times of its diameter and has a horizontally oriented central axis;
- b) the carrier is charged in an amount of 10 to 60% of a capacity of the treatment container;
- c) the step of carrying out simultaneous revolving and rocking revolves the treatment container at 5 to 60 rpm around the central axis;
- and
- d) the step of carrying out simultaneous revolving and rocking rocks the central axis at 1 to 12 spm in an upward and downward rocking angle of 5 to 90° C.
