In the specification and claims, we have defined the catalytic and physical characteristics of the microspheres of the present invention in relation to the characteristics of a sample of a commercially available product, Ultrasiv.RTM. 260 catalyst, small amounts of which can be obtained for testing purposes by writing to Engelhard's Minerals and Chemicals Division Patent Department. Hereinafter, this sample of Ultrasiv.RTM. 260 catalyst is referred to in this application (including the claims) as "standard commercial catalyst."
We believe that defining the catalytic and physical characteristics of the microspheres of the present invention in relation to a standard commercial catalyst, rather than in absolute numerical values, is a more precise way of defining those characteristics. The reason for this is that the numerical values of those characteristics will vary, depending on the operator who conducted the tests and the laboratory equipment the operator used, while the relative values of those characteristics as compared to a standard will remain relatively constant even when those relative values are determined by different operators using different laborator equipment.
When the microspheres of the present invention contain more than about 4% by weight rare earth oxides, they have excellent hydrothermal stability. In particular, their deactivated and severely deactivated activities are at least about 1.5 times greater than, and preferably at least about 2.0 times greater than, that of standard commercial catalyst.

在规格和要求, 我们定义了出席发明的microspheres 的催化作用和物理特性关于一个商业可利用的产品的样品的特征, Ultrasiv 。RTM 。 260 催化剂, 可能被获得为测试目的由写给Engelhard 的矿物和化学制品分部专利部门的少量。 以后, Ultrasiv 这个样品。RTM 。 260 催化剂指在这种应用(包括要求)"标准商业催化剂。"
我们相信那定义出席发明的microspheres 的催化作用和物理特性关于一种标准商业催化剂, 而不是按绝对数值, 是定义那些特征一个更加精确的方式。 这的原因是, 那些特征的数值将变化, 依靠进行测试并且实验室设备操作员使用的操作员, 当那些特征的相对值与标准比较将依然是相对地恒定既使当那些相对值由不同的操作员确定使用另外laborator 设备。
当当前发明的microspheres 包含更多比大约4% 由重量罕见的地球氧化物, 他们有优秀热液稳定。 特别是, 他们的被撤销的和严厉地被撤销的活动是至少大约1.5 次大于, 并且更好地至少大约2.0 次大于, 那标准商业催化剂。
