A statistical experimental design was employed to study the effects of pressure, temperature, catalyst loading, and mixing speed on the solubilities ( C *) and volumetric gas/liquid mass transfer coefficients ( k L a ) for H 2 , N 2 , CO, CH 4 and C 2 H 4 in a liquid mixture of hexanes containing iron oxide catalyst in a 4‐litre agitated autoclave. Statistical correlations for k L a values for the gases used were developed. Mixing speed and solid concentration showed the strongest effects on k L a . At low catalyst concentrations, a maximum in k L a was observed and at concentrations > 37 mass%, k L a decreased by more than one order of magnitude.
