Promoter Concentration and Catalysis

摘要: IN a recent publication1 attention has been directed to the critical concentration of silica required give maximum increase in activity molybdenum oxide catalysts used decomposition hexane at 500°. A survey now made with wide range other promoters, and it is found that case oxides sodium, chromium, cerium, aluminium, barium, boron thorium, ratio number atoms these elements 100 same as previously observed silicon.
