✦ Synopsis

For catalytic hydrogenation and oxidation reactions in protic solvents on a conducting catalyst the mass transfer can be enhanced due to electrochemical transport of ions. Numerical simulations of a hydrogenation reaction on a suspended catalyst particle show that this transport can increase the overall reaction rate more than an order of magnitude. The selectivity and the dynamic behaviour of the catalyst are also affected by electrochemical phenomena.

The absorption of CO in aqueous NaOH--n-hexane dispersions has been investigated in an agitated reactor over a temperature range of 353-433 K. The rate of absorption was found to be significantly enhanced in the presence of organic droplets and an emulsifier. Also, the addition of a phase-transfer c
