ZSM-5 has been investigated for promoting conversion of palmitic acid to aromatics in the presence of a supercritical water phase at concentrations lower than previously studied. The rate of palmitic acid decomposition is roughly 50в greater than comparable previous reports. The catalyst was reused four times with modest activity loss after the first cycle and negligible loss for all subsequent cycles. Post-reaction characterization of ZSM-5 revealed less degradation than previously reported. Time studies and control experiments in the absence of catalyst were used to elucidate the thermal and catalytic contributions to the product distribution. The current study opens new avenues for catalytic upgrading of renewable oils in the presence of supercritical water.
