钒催化剂抗机械强度的高低直接关系到它的使用寿命,是考核其产品质量的重要指标之一。但是,我国生产的几种型号的钒催化剂,其强度检测条件和测定方法均不统一(见表1),有测定其颗粒正压(即轴向强度)的,有测 Vanadium catalyst anti-mechanical strength is directly related to the level of its service life, is to assess the quality of its products, one of the important indicators. However, several types of vanadium catalysts produced in China are not uniform in strength detection conditions and determination methods (see Table 1), and have a positive pressure (ie, axial strength)
