Abstract

Monolith catalysts are effective for partial oxidation reactions at high temperatures at contact times between 10−4 and 10−2 sec. We summarize results for three reactions: (1) syngas by direct oxidation of CH4, (2) olefins by oxidative dehydrogenation of alkanes, and (3) HCN by ammoxidation of CH4, and we consider what features of monoliths create optimal selectivity with high conversions. Monoliths used are noble metal films coated on ceramic foams, extruded ceramics, ceramic fibers, and woven Pt-10%Rh gauze catalysts. Effects of metals and geometries of the ceramics are ceramics are compared to show how these factors influence activity and selectivity.
