失活渣油加氢催化剂由于沉积物成分复杂,在程序升温氧化(TPO)实验过程中对仪器污染比较严重,容易造成管线和某些部件的腐蚀和堵塞。本文总结了失活渣油加氢催化剂在TPO实验过程中经常出现的故障、现象和解决方法,并针对此类催化剂的TPO的实验方法进行了适当改进。 Incomplete residual oil hydrogenation catalyst due to the complex composition of the sediment in the process of temperature oxidation (TPO) during the experiment more serious pollution of the instrument, likely to cause corrosion of pipelines and certain components and plugging. This paper summarizes the frequently occurring failures, phenomena and solutions of the deactivated residue hydrogenation catalyst during the TPO experiment. The TPO experimental method for such catalysts has been properly improved.
