As an indispensable key equipment in modern chemical industry, the importance of catalyst tablet press is self-evident. In this paper, the definition, working principle, structure, classification and application 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 unchanged before and after the chemical reaction, and it is the "booster" in the chemical reaction ". According to statistics, about 90% of industrial processes use catalysts, and the catalyst tablet press is an important tool to ensure that the catalyst can function efficiently and stably.

The working principle of the catalyst tablet press mainly involves the acquisition and analysis of infrared spectra. Measure the background spectrum, then collect the sample spectrum, and the system will automatically calculate the transmission spectrum or absorption spectrum of the sample. These spectral patterns can be converted into each other to obtain the spectral information of the catalyst itself. If the user needs to study the adsorption/desorption performance of the catalyst, the catalyst sample can be directly measured as the background, and then the probe molecules are introduced for adsorption/desorption to observe the infrared absorption of the probe molecules on the surface of the catalyst.

The catalyst tablet press is mainly composed of key components 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 includes other auxiliary components, such as infrared spectrometer, sample chamber, control system, etc., to ensure the smooth progress of the entire work process.

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 without phase boundary is called homogeneous catalysis. Catalysts that can act as homogeneous catalysts are called homogeneous catalysts, such as liquid acids, alkalis, Xerox solid acids, alkalis and soluble transition metal compounds.

Heterogeneous catalysis: Heterogeneous catalysts are used for reactions in different phases, that is, they are in different states from the reactants they catalyze. For 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 consumption, environmental protection and other aspects of great significance.
