(258e) Electrochemical Hydrogenation of Bio-Oil Compounds Using a Polymer Electrolyte Membrane Reactor
AIChE Annual Meeting
Tuesday, October 31, 2017 - 9:40am to 10:05am
The main challenge in ECH using a proton exchange membrane reactor is that a large fraction of current goes towards generating hydrogen gas that is not used in the hydrogenation reaction. High current efficiency (59.7%) could be achieved by using a PEMFC reactor. The mild operation condition is the greatest advantage of the proposed method, the optimized reaction condition is at 65 ºC and 1 atmosphere. Relative humidity positively effects H2 Utilization Efficiency and Current Efficiency, while temperature did not show linear influence during acetone ECH. The challenging part was the membrane contamination. Suitable reaction pressure, low reaction temperature, and low reaction relative humidity could prolong membrane life.
