使用功能性表面催化剂组合物的选择性氢化方法
摘要：
本发明涉及使用一种催化剂组合物的选择性氢化方法，其中该催化剂组合物优选包含玻璃基材，在基材表面上和/或其中结合一种或多种功能性表面活性成分。基本无孔基材具有(i)为约0.01m2/g－10m2/g的总表面积，(ii)在pH值大于0的范围内获得的预定等电点(IEP)，优选pH值大于或等于4.5，更优选大于或等于6.0并小于或等于14。至少一个催化活性区域为连续或不连续，平均厚度小于或等于约30纳米，优选小于或等于20纳米，更优选小于或等于10纳米。优选基材是SARCNa小于或等于约0.5的玻璃组合物。
摘要（英）：

Selective hydrogenation processes using a catalyst composition which, preferably comprises a glass substrate, with one or more functional surface active constituents integrated on and/or in the substrate surface. A substantially nonporous substrate has (i) a total surface area between about 0.01 m/g and 10 m/g; and (ii) a predetermined isoelectric point (IEP) obtained in a pH range greater than 0, preferably greater than or equal to 4.5, or more preferably greater than or equal to 6.0, but less than or equal to 14. At least one catalytically-active region may be contiguous or discontiguous and has a mean thickness less than or equal to about 30 nm, preferably less than or equal to 20 nm and more preferably less than or equal to 10 nm. Preferably, the substrate is a glass composition having a SARCNa less than or equal to about 0.5.
