Abstract

The present invention relates to a multifunctional deoxidizer and a preparation method thereof, wherein the multifunctional deoxidizer comprises a suitable metal carbonate, a proper amount of an activity promoter and a proper amount of a structure support monomer. During a multifunctional deoxidizer production process, a thermal decomposition (calcination) method is used to decompose a metal carbonate to form the active component of the metal oxide deoxidizer while release carbon dioxide gas, such that a large number of uniform adsorption pore sizes having the carbon dioxide molecule size are formed in the multifunctional deoxidizer, and the pore size can deeply adsorb a lot of water and carbon dioxide. According to the present invention, the novel gas purification material is provided, the production process can be simplified, the production energy source and the materials can be saved, and the production cost and the consumption can be reduced; and the energy saving and consumption reducing industrial policy direction in the country new material and new technology application can be met.

Description

technical field [0001] This project belongs to the field of new materials and new technologies. The invention provides a new type of gas purification material, specifically a multifunctional deoxidizer and its preparation method and application. It is specially designed for the purification of raw material gas (ethylene, propylene, etc.) and auxiliary gas (nitrogen, hydrogen, etc.) The multi-functional deoxygenation adsorbent researched and developed for the purification of ultra-pure and ultra-high-purity gases can purify them in one process and remove oxygen, water and carbon dioxide at the same time. Background technique [0002] This project is an energy-saving and consumption-reducing project in the field of materials, which is of international advanced level. The new multi-functional deoxidizer material invented by this project enables the deoxidation, dehydration and decarbonation of the purification process in the industrial production process to use only one purifi...
