Influence of Ceria Modified Support on Steam Reforming of Acetic Acid Using Ni-Ru/CeO2-Al2O3 Catalysts

摘要

Concerning the great demand for energy and depletion of fossil fuel reserves, as well as the environmental pollution problems caused by automobile exhausts and industrial production in recent years, finding a new and alternative energy is becoming very urgent. Hydrogen is regarded as a clean and highly efficient energy resource to generate electricity via a fuel cell. Biomass can be easily transformed into bio-oil by fast pyrolysis, in which process biomass is heated to high temperature rapidly in the absence of oxygen. Then hydrogen can be produced by steam reforming of bio-oil with involvement of catalyst. However, the traditional catalysts can be easily deactivated because of the severe coke formation on the catalyst. Therefore, it is urgent to develop a novel catalyst with a high activity and good ability to inhibit the formation of coke.
