| abstract |
The invention relates to the technical field of catalysts, and provides a cylindrical porous carrier and a preparation method thereof, and a catalyst and application thereof. The carrier layer of the cylindrical porous carrier is arranged into a corrugated shape or a honeycomb shape, so that the surface area of the carrier layer can be increased, and the contact area between gas and the carrier layer is increased. The cylindrical porous carrier is used for preparing the catalyst, so that the resistance of gas passing through a catalyst layer can be obviously reduced, and the running cost of a system can be reduced; in addition, the catalyst provided by the invention is convenient to install, low in cost and wide in application prospect. |
