Investigation of the conveyor drying of a zeolite-containing spherical catalyst

To ensure satisfactory mechanical properties in an AShNTs-1 catalyst with a minimum degree of cracking during the drying process, the conditions for its dehydration should be considerably milder than those used for an aluminosilicate catalyst
The influence of the surface-active substance OP-7 for the prevention of cracking of grains of AShNTs-1 catalyst is more effective the lower the content of zeolite in the catalyst.
Based on the experiments made, a set of drying conditions was determined which is close to the optimal; the parameters are the following: t8=142°C; τ=5.3 h; H=82 mm.
