Reaction activation energy of the various catalysts is obtained from resulting trend line to calculate the slope. The reaction of carbon deposition to occur needs a certain size of metal particles, so active component of smaller particles hinders the role of cobalt adjacent in the process of carbon deposition, which is conducive to inhibit carbon deposition. Therefore, Ni/CeO2 catalyst at atmospheric pressure performs high stability due to the ability to resist Ni sintering and carbon deposition. |
