Effects of current upon hydrogen production from electrochemical catalytic reforming of acetic acid

Production of hydrogen from acetic acid (HAc) was performed by using a novel electrochemical catalytic reforming (ECR) approach over the 18%NiO/Al₂O₃ catalyst. ECR was carried out in a fixed-bed continuous flow reactor, where an ac electric current was passed through the catalyst. A high yield of hydrogen (>90%) and carbon conversion (>90%) were obtained as the reforming temperature over 400 °C via the ECR approach. The influences of the current on the HAc decomposition, its reforming, and the catalyst reduction in the ECR process have been investigated, which were compared with those in the common steam reforming (CSR) route. The mechanism of the HAc reforming in ECR was also discussed based on the present investigation.
