It is established in studies of the thermal conductivity and thermal
diffusivity a of granulated porous catalysts and their supports that in
gaseous mixtures and a for a catalyst load is determined by the properties
of the main component of the mixture, and an increase in and a of catalysts
under investigation is observed in the region of stresses that disintegrate
the granules. The quantities and a of a load of a catalysts and support
increase with increasing thermal conductivity of the filling gas, granule
dimensions, concentration, and thermal conductivity of metallic additives.
The values of and a of a catalyst load decrease linearly with increasing
total volume of pores and specific surface.
