摘要

NiO与NiCl 2 (g)和o2 (g)反应沉积在过滤器孔壁上,NiCl 2 (g)和o2 (g)分别在过滤器的相对侧(即内外侧)进料。常用氧化铝过滤器平均孔径为1 μn,孔径为10mm,厚度为1mm。该NiO沉积过滤器经氢活化形成Ni/ al2o3催化剂,然后测定催化剂的甲醇分解活性。结果表明,催化剂组分的增加使催化剂的比催化活性增加,但镍沉积有一个最优值。由于催化剂的形状有利于降低反应物通过催化剂的压降,因此该催化剂可用于处理大量减少反应物通过催化剂的压降,因此该催化剂可用于处理大量流动。发现它是一种很有前途的甲醇汽车车载裂化催化剂。

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.
