As an indispensable key equipment in modern chemical industry, the i÷mportance of catalyst tablet press is self-evident.≤ In this paper, the definition, working principle, structure, classification and applicatioφn fields of catalyst tablet press are described in detail.

The catalyst tablet press is a device that can affect the chemical reaction by changing the ÷chemical reaction rate of the reactants without changing the  chemical balance. Its quality and chemical properties remain un★changed before and after the chemical reaction, and ‌it is the "booster" in the chemical reaction ". According to statistics, about 90% of indus↓trial processes use catalysts, and the catalyst tab let press is an important tool to ensure that the catalyst can functio♣n efficiently and stably.

The working principle of the catalyst tablet press mainly inv'olves the acquisition and analysis of infrared spectra. Measure the background spec≠trum, then collect the sample spectrum, and the system will automatically calculate t he transmission spectrum or absorption spectrum of the sample. T$hese spectral patterns can be converted into each other to obtain the spectral information oδf the catalyst itself. If the user needs to study the adsorption/desorption perf​ormance of the catalyst, the catalyst sample can be directly measure£d as the background, and then the probe molecules are introduced for adsorption/desorption to o£bserve the infrared absorption of the probe molecules on the surface of' the catalyst.

The catalyst tablet press is mainly composed of key comp≤onents such as the turntable structure. The turntable is the$ main execution part of the equipment work, responsi‌ble for the pressing and forming of the catalyst. In addition, the equipment also includ<es other auxiliary components, such as infrared spectrometer, samp×le chamber, control system, etc., to ensure the smooth progress of the entire work proβcess.

According to different classification methods, the catalysts of the catalyst tablet press can be ≈divided into the following categories:

Homogeneous catalysis: the catalyst and the reactant are in the same phase, and the reaction withΩout phase boundary is called homogeneous catalysis. Catalysts that ™can act as homogeneous catalysts are called homogeneous catalysts, such as liq∞uid acids, alkalis, Xerox solid acids, alkalis and solubl£e transition metal compounds.

Heterogeneous catalysis: Heterogeneous catalysts are used for reactions in differen↑t phases, that is, they are in different states from the reactants they catalyze. F☆or example, in the production of margarine, unsaturated vegetable oils and hydrogen can be conv‌erted to saturated fats by solid nickel, which is a heterogeneous catalyst.

Catalyst tablet press is mainly used in electronics, food,≤ daily necessities, medicine and other industrial sectors, its wide range of applications, ¥to improve production efficiency, reduce energy coεnsumption, environmental protection and other aspects of great significance.
