ALUNDUM* Low Surface A r e a C a t a l y s t Carriers ... add speed and efficiency to many processing reactions Crystalline in nature, Norton ALUNDUM catalyst carriers have excellent mechanical, thermal and chemical stability. The most widely used type has low surface areas of less than lm 2 /gram, combined with high alumina content of 77% to 92%. Shapes and Sizes: low surface area type; spheres % " to iy2" diameter; pellets Vs" χ Vs" to V2" χ ]/{'; rings Y%" χ %" χ %" O.D. to 1" xiy/x VA" O.D. Other Physical Properties: apparent porosity 10-50%; water absorption 3-25%; bulk density 1.90-3.15 gr/cc; volume bulk density 65-80 lbs/ft 3 ; crystal structure alpha alumina and mullite. Typical Applications: processing phthalic anhydride, maleic anhydride and ethylene oxide; also in protective atmospheres and synthetic gas generation.
Suspending
active catalysts
effectively Inert Supports
In fixed bed converters, Norton inert supports are located to suspend active catalysts at given levels, as shown in diagram. Made of dense, rugged, elec trically fused materials they have great resistance to breakdown and no chemi cally reactive effect on the processing.

supports
are produced by Norton with intermediate surface areas. On request, any type may be prepared from other materials, such as CRYSTOLON* silicon carbide, MAGNORITE* fused magnesia, zirconium oxide, silica, etc. For further facts call in your Norton Refractories Engineer, or write to NORTON COMPANY, Refractories Division, 527 New Bond Street, Worcester 6, Massachusetts.
