Technical Field

Ultra-high purity gases are indispensable basic supporting raw materials for the production of electronic industries such as LEDs, solar cells, and large-scale integrated circuits. They are mainly used as carrier gases and protective gases in the production process of the electronic industry. Their purity is crucial to the quality and performance of the products.

Gas purification is a technology that uses chemical or physical methods to separate impurity components in the gas and reduce the impurity components to a certain standard. The chemical method is to allow the impurity components to undergo a reversible or irreversible chemical reaction with the catalyst in the purifier, fix the impurities and allow the raw gas to pass smoothly, thereby achieving the purpose of purifying the raw gas.

For example, the technical principle of chemical nitrogen purification is: first, the nitrogen in the nitrogen is purified by catalytic oxidation process. , as well as First, remove the nitrogen using a precious metal catalyst. , , and A chemical reaction occurs, producing and Then, the deoxygenation adsorption process is used to remove , and Remove to ensure that the nitrogen reaches class.

Catalysts are key factors in promoting chemical reactions. During the catalytic oxidation process, the oxygen content in nitrogen will fluctuate. This fluctuation will not have a significant impact on the catalyst within the normal range.
