Abstract

A rectangular-solid packaged catalyst assembly made up of a plurality of rectangular-solid unit catalysts stacked and assembled together, the unit catalysts having a honeycomb structure with a multiplicity of gas passages each. Heat-resistant packings are used to cover at least the vertices and the neighboring areas of the faces of the unit catalysts other than the gas-passage faces and also to cover the edges of the gas-passage faces surrounding the gas passages, the packings being integrally secured to the unit catalysts and packaged together in a rectangular-solid housing. Retaining strips are placed over the packings on the edges of the gas-passage faces on at least either the gas inlet or outlet ends of the unit catalysts and are securely attached to the housing.
