摘要
催化裂化催化剂显微观测图像技术是用于流化催化裂化装置反应再生系统运行故障诊断的技术。严格的操作程序是获得清晰图像并具有可比性的可靠保证。阐述催化裂化催化剂颗粒显微观测实验室建设过程中的注意事项,包括显微照相设备的选择、实验室配置、样品制作和图像处理等,对操作过程进行标准化管理,保证了图像的可靠性和可比性。目前,该技术在装置事故的诊断上初显威力,对减少催化剂跑损和判断三旋效率具有指导作用。
The microscope image technique for observing FCC catalysts is an emerging method for diagnosing the running fault of reaction-regeneration system of the fluid catalytic cracking units. The strict operation procedure is reliable guaranty to obtain the clear images and their comparability. Using this method to observe FCC catalyst particles,some matters needed to be paid attention to during the laboratory construction such as the selection of a microscope model,laboratory configuration,sample preparation and image processing was summarized. Standardization management of operation process ensured the reliability and comparability of the images. At present this technology has played an important role on fault diagnosis, especially on catalyst loss and the efficiency of third-stage cyclone.
