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