(上接第7期第41页)[048]催化剂包含第一种金属,可以选择的一到两类第二种金属,第三种金属或者其他一些金属。在本文里提到用来修饰金属“第一”“第二”“第三”是相应金属和其他金属有区别。载体材料的总质量最好占催化剂的0.1-25%,比如从0.1到15%或者从0.1%到10%。为了达到说明书功能,除非有特殊的说明,所有的质量分数都是依据催化剂总质量包括 (Continued on page 7, 第 41 页) [048] The catalyst comprises a first metal, one or two types of second metal, a third metal, or some other metal of choice. Mentioned in this article used to modify the metal “first ” “second ” “third ” is the corresponding metal and other metals are different. The total mass of the support material preferably represents 0.1-25% of the catalyst, such as from 0.1 to 15% or from 0.1% to 10%. In order to achieve the function of the specification, unless otherwise specified, all mass fractions are based on the total mass of catalyst, including
