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.

由含有少量金属氧化物的硼硅酸盐玻璃制备负载在多孔玻璃上的镍催化剂。通过苯类(苯、甲苯、邻二甲苯、间二甲苯、1,3,5-三甲苯和1,2,3-三甲苯)与己烯(1-己烯)的加氢反应考察了镍催化剂的催化活性。 , 4-甲基-1-戊烯和3, 3-二甲基-1-丁烯）阐明了金属氧化物的添加对微孔结构的影响多孔玻璃。通过固定床催化反应器测量的苯和己烯的氢化速率表明，多孔玻璃的微孔尺寸受到母玻璃中添加金属氧化物的强烈影响。当硼硅酸盐玻璃中添加3wt%的氧化铝时，微孔尺寸减小至0.8 nm。结果，分子尺寸最大的1,2,3-三甲苯在负载的镍催化剂上的氢化速率基本为零。由含有4.5wt％氧化铝的硼硅酸盐玻璃制备的多孔玻璃。氧化锆和氧化镧的添加对于控制多孔玻璃中的微孔尺寸也有效。由于多孔玻璃是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最初的目的。
