Preparation of Onboard Reforming Catalyst for Methanol by Chemical Vapor Deposition

NiO deposited on the wall of the pore of the filter by the reaction with NiCl 2 (g) and O 2 (g). NiCl 2 (g) and O 2 (g) are separely fed at the opposite side of the filter(namely inner and outer side). Used alumina filter is mean pore diameter 1 μn, o.d. 10 mm, thickness 1 mm. This NiO deposited filter was activated by hydrogen to form Ni/Al2O 3 catalyst, then the catalyst was measured methanol decomposition activity. From the results, increment of catalytic component increases the specific catalytic activity, but hty have an optimal value of Ni deposition. As the shape of the catalyst is favorable to reduce the pressure drop of reactant through the catalyst, this catalyst may be available to treat massive reduce the pressure drop of reactant through the catalyst, this catalyst may be available to treat massive flow. It was found that it is a great catalyst of promise to onboard cracking for methanol automobile.
