摘要
主要针对市售鹅颈管难以达到催化剂磨损指数评价要求的问题进行探索研究,以已知磨损指数结果的标准样品为参考,对市售鹅颈管中毛细管弯曲角度进行二次加工,调整毛细管中空气流方向与催化剂样品表面的角度,使其满足催化剂磨损指数分析评价要求,减少鹅颈管差异引入的仪器误差,提高磨损指数评价结果准确度。
The commercial swan-neck tubes need to be improved because of its deficiency in attrition index analysis of FCC catalysts. The capillary bending angle of the swan-neck tube was adjusted to change the angle between the airflow direction and standard sample surface. Using the standard sample with known abrasion index as the reference sample and improved swan-neck tube, the abrasion index of the standard sample was abtained, which met the requirements of analysis and evaluation of the catalysts, reduced the instrument error of swan-neck tube and improved the accuracy of abrasion index results.
