Abstract

The invention relates to palladium / carbon catalyst hydrogenation activity evaluating method and device. The device comprises a reaction evaluating bottle arranged on an electromagnetic stirrer, a vacuum pump, a hydrogen inlet pipeline and a valve, a vacuum pressure sensor and an emptying pipe, wherein the electromagnetic stirrer is provided with a time relay and a stirrer voltage meter; the vacuum pump is connected with the reaction evaluating bottle through a pipeline and a valve; the hydrogen inlet pipeline and the valve are connected with the reaction evaluating bottle; the vacuum pressure sensor is connected with the reaction evaluating bottle, a pressure recorder is connected with the vacuum pressure sensor; and the emptying pipe is provided with an emptying electromagnetic valve. The invention judges the hydrogenation property of a palladium / carbon catalyst by adopting a method of measuring hydrogen consumption of reaction liquid within unit time per catalyst during the reaction without being evaluated by practical reactions. Active results of a new catalyst and an old catalyst are rapidly compared and clear, therefore, the invention is also suitable for the hydrogenation property evaluation of the palladium / carbon catalyst and other palladium / supporter catalysts.

Description

technical field [0001] The invention relates to a detection device and a detection method for the activity of a palladium / carbon catalyst. Background technique [0002] The existing palladium / carbon catalyst activity detection mainly relies on: atomic absorption method, electron microscope method, hydrogen-hydrogen adsorption method, etc. to detect indicators such as palladium content, palladium grain dispersion degree, etc., which can only indirectly reflect its activity. The activity of the catalyst can only be accurately detected through the actual reaction experiment. In order to be safe in production, before large-scale feeding, small-scale production method of feeding is often used to test the activity of new catalysts. Some actual reactions require high temperature and high pressure conditions, which is troublesome and time-consuming. The evaluation of the performance of a catalyst is, in the final analysis, its activity detection. Contents of the invention [000...
