Abstract:
A process for monitoring the condition of a guard bed catalyst material used in an adiabatic reactor to thereby protect a primary reaction catalyst and, in particular, the present invention is intended to be applied to a guard bed used prior to the heterogeneous catalyzed esterification of free fatty acids with low molecular weight monohydric alcohols, especially methanol, to produce fatty acid alkyl esters for biodiesel production.
