A nickel catalyst supported on the porous glass was prepared from borosilicate glass containing a small amount of metal oxide. The catalytic activity of the nickel catalyst was investigated by the hydrogenation reaction of benzenes(benzene, toluene, o-xylene, m-xylene, 1, 3, 5-trimethylbenzene and 1, 2, 3-trimethylbenzene) and hexenes (1-hexene, 4-methyl-1-pentene and 3, 3-dimethyl-1-butene) to elucidate the effect of the addition of metal oxide on the micropore structure of the porous glass. The hydrogenation rates of benzenes and hexenes measured by a fixed-bed catalytic reactor revealed that the micropore size of the porous glass was strongly affected by the addition of metal oxide into the mother glass. When 3wt% of alumina was added in the borosilicate glass, The micropore size decreased to 0.8 nm.As the results, the hydrogenation rates of 1, 2, 3-trimethylbenzene, having largest molecular size, was essentially zero over the nickel catalyst supported on porous glass prepared from the borosilicate glass containing 4.5 wt% of alumina. The addition of zirconium oxide and lanthanum oxide were also effective for the controlling of micropore size in the porous glass.Since the porous glass is an effective catalyst support with molecular shape selectivity, this investigation is considered to accomplish the initial purpose.

以含少量金属氧化物的硼硅酸盐玻璃为原料，制备了负载在多孔玻璃上的镍催化剂。通过苯(苯、甲苯、邻二甲苯、间二甲苯、1，3，5-三甲苯和1，2，3-三甲苯)和己烯(1-己烯、4-甲基-1-戊烯和3，3-二甲基-1-丁烯)的加氢反应考察了镍催化剂的催化活性，以阐明金属氧化物的加入对多孔玻璃微孔结构的影响。用固定床催化反应器测定了苯和己烯的加氢速率，结果表明，金属氧化物的加入对多孔玻璃的微孔尺寸有很大的影响。当氧化铝加入量为3wt%时，玻璃的微孔尺寸减小到0.8 nm。结果表明，分子尺寸最大的1，2，3-三甲苯在由氧化铝含量为4.5wt%的玻璃制备的多孔玻璃负载的镍催化剂上的加氢速率基本为零。氧化锆和氧化镧的加入也有效地控制了多孔玻璃中的微孔尺寸，由于多孔玻璃是一种具有分子形状选择性的有效催化剂载体，因此本研究被认为达到了初步目的。
