Abstract

The kinetics of ethylene oxidation by air over a supported silver catalyst were investigated in the temperature range 490–620 K. The reaction network was found to be triangular. Under virtually constant oxygen partial pressure (0.2 bar), the following rate relationships, (in mol g^βˆ’1^s^βˆ’1^) were found: (formulae in curved brackets denote partial pressures)

The given rate expressions are discussed in the framework of earlier kinetic investigations.

## Abstract **Summary:** Silica supported chromium oxide catalysts have been used for many years to manufacture polyethylene and they still account for more than 50% of world production of high‐density polyethylene. Along with its commercial success, the catalytic mechanism and polymerization kinet
