查询词典 catalytical

But there is not report about comparison between microparticle and nanoparticle, pure ZSM-5 and co-crystalline, unsupported and supported ZSM-5 zeolite in physicochemical and catalytical characters.

但将其微米颗粒与纳米颗粒、纯ZSM-5与混晶、非负载与负载型分子筛放在一起进行系统的物化性能和催化性能研究对比的工作尚未见报道。

The physical and chemical properties of the purified MPH were studied. In the crude extracts, the specific activities of MPH for methyl parathion and fenitrothion were higher than those of OPH from F.sp, while the catalytical activity for parathion was lower than that of OPH.

我们根据Pseudomonas sp WBC-3的生长特性及产酶情况，以阳离子交换层析纯化胞内粗蛋白中，使酶的比活提高了49.1倍，得到了均一的目的蛋白MPH，SDS-PAGE验证为单一的条带，。

Secondary growth of silicalite-1-seeded industrial CuO-ZnO-Al2O3 in alkaline solution with silica and alumina source produced intergrown ZSM-5 zeolite shells. After the shells were changed into HZSM-5, we compared the catalytical performance of the core/shell composite catalyst with a non-core/shell structured composite catalyst with the same component.

铜锌铝催化剂（CuO-ZnO-Al2O3）是工业上制备二甲醚的良好催化剂，我们将其表面预先包覆纳米沸石silicalite-1晶种，水热环境下二次生长后吸收硅源、铝源后形成ZSM-5膜，转换成氢型后形成CuO-ZnO-Al2O3/HZSM-5的核/壳结构复合催化剂。
