一种固体颗粒强度的测试方法
摘要：
本发明公开了一种固体颗粒强度的测试方法，所述固体颗粒为催化剂载体颗粒或催化剂颗粒，该方法包括：(1)将固体颗粒与溶剂混合，得到含有固体颗粒的混合物；(2)将步骤(1)得到的含有固体颗粒的混合物进行超声处理，并对超声处理t1、t2、t3时间后的固体颗粒进行粒度检测，得到粒度D(t1)、D(t2)和D(t3)，所述D(t1)、D(t2)和D(t3)采用相同的累计粒度分布百分数；(3)计算固体颗粒的强度指数L，所述固体颗粒的强度指数L的计算通过下式进行；其中，所述超声处理的时间满足t1＜t3＜t2。本发明提供的固体强度的测定方法重复性好并且精密度高，能够对催化剂载体强度或催化剂强度进行有效的监控。
摘要（英）：

The invention discloses a method for testing strength of solid particles. The solid particles are catalyst carrier particles or catalyst particles. The method comprises the following steps: (1) solid particles are solvents are mixed, in order to obtain a mixture containing solid particles; (2) ultrasonic treatment is carried out for the mixture containing solid particles which is obtained in the step (1), after the ultrasonic treatment is carried out for t1, t2 and t3, particle size detection is carried out for the solid particles, the particle size D(t1), D(t2) and D(t3) are obtained, and D(t1), D(t2) and D(t3) employ the same cumulative particle size distribution percent; (3) strength index L of solid particles is calculated, and the strength index L of solid particles is calculated according to the following formula; wherein the ultrasonic treatment time satisfies t1
