ABSTRACT:
Refractory catalyst supports are secured in metallic containers having different coefficients of thermal expansion by providing at least one layer of a resilient thermally resistant inorganic sheet material or paper between the support and casing and securing the paper and catalyst support in the container by foaming an inorganic material in the space between the sheet material or paper and catalyst support. A further layer of sheet material or paper may be provided adjacent the support with the foam between the separate layers of sheet material.
