Preparation of Onboard Reforming Catalyst for Methanol by Chemical Vapor Deposition

Abstract
NiO deposited on the wall of the pore of the filter by the reaction with NiCl2(g) and O2(g). NiCl2(g) and O2(g) are seprtely fed at the oppsite side of the filter(namely inner and outer side). Used alumina filter is mean pore diameter 1µn, o.d. 10mm, thickness 1 mm. This NiO deposited filter was activated by hydrogen to form Ni/Al2O3 catalyst, then the catalyst was measured methanol decomposition activity. From the results, increment of catalytic component increases the specific catalytic activity, but they have an optimal value of Ni deposition. As the shape of the catalyst is frivorable to 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.
