Catalytic method for obtaining hydrogen or a hydrogen-rich gas starting from bioethanol and/or ethanol

摘要

The invention relates to a catalyst which is used to obtain hydrogen or a hydrogen-rich gas that is suitable for use in fuel cells or other applications from bioethanol and/or ethanol, comprising a support, a promoter agent and an active phase which is incorporated into the support, said catalyst taking the form of a calcinated solid in which the support comprises at least one oxide with high surface mobility and is modified with the promoter agent. According to the invention, the promoter agent comprises at least one oxide of a rare earth that is selected from the lanthanide group and the active phase comprises at least one oxide of a transition metal from group VIII or IB.
