A statistical approach was developed to investigate the effects of pressure, temperature, mixing speed and solid concentration on k L a for gaseous hydrogen, ethylene, and propylene in liquid n ‐hexane containing solid polypropylene powder in a 4‐litre agitated reactor. The solubilities of the gases appeared to follow Henry's Law. Statistical correlations to predict k L a were proposed and response surfaces were constructed. k L a values appeared to reach a maximum around 15 mass% and sharply decrease above 30 mass%. The effects of pressure and temperature on k L a were found to depend on the gas‐liquid system and operating conditions used.
