Supported palladium catalysts for the hydrogen-free decarboxylation of fatty acids deactivate severely after one use. Here, the recyclability of a well-defined, mesoporous silica-supported Pd catalyst is evaluated in the batch decarboxylation of stearic acid at 300 °C.  Catalyst deactivation is examined via myriad characterization techniques.  Catalyst regeneration methods are developed.
