Description

technical field [0001] The invention relates to a catalyst aging furnace, in particular to an aging furnace for evaluating the hydrothermal stability of molecular sieves, catalysts, etc., which is used for catalyst aging in a laboratory. Background technique [0002] Catalysts are widely used in petroleum, chemical and other fields. Many catalytic processing processes are completed under the action of catalysts. The performance of the catalyst directly affects the product yield and product quality. Therefore, it is very important to develop and research catalysts with superior performance. In the process of catalyst research and development, the evaluation of catalyst performance and other properties requires various experimental devices and process methods, and the aging of catalysts is the first step in various evaluations of catalysts. [0003] Such as catalytic cracking fresh catalyst activity is high and unstable, not representative. When researching and evaluating c...

Problems solved by technology

However, this method adopts the method of entering water vapor from the upper part, and there is a back-mixing phenomenon of water vapor in the roaster, and the exhaust gas generated by the aging of the sample will affect the sample; the rotating shaft is supported by the upper and lower ends, and the support points are far apart. Requires high precision and poor workmanship; in addition, two high-temperature sealing points reduce the safety of device operation
