The properties and behavior of Pd-carbon fiber deoxygenation catalyst and its carrier are measured and studied by employing low temperature N2 adsorption

H2 chemisorption and dynamic analysis. The results show that high performance of Pd-carbon fiber deoxygenation catalyst is responsible for its physical and chemical characteristics. The resistance of mass transfer is much lower for the fiber catalysts than the granular ones. Heavy H2 spillover in the system of H2-Pd-carbon fiber may happen and H2-O2 reaction within the micropore of carbon fibers may possibly occur. The reaction between adsorbed oxygen and spillover hydrogen on the surface of the micropore may play an important role in the deoxygenation process of the fiber catalyst. Results measured comfirmed that the assumptions made in previous theoretical approaches appear to be valid.
