Research Abstract

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.
