Abstract

The invention belongs to the field of biomass gasification catalysts, and particularly relates to a preparation method of an energy-saving corrosion inhibition type decarburizing agent. According to the invention, under the action of the catalyst, ethylene carbonate and methylamine are adopted as basic raw materials to synthesize N-methyldiethanolamine, and then 1, 3-propane sultone is adopted to modify N-methyldiethanolamine, so that the carbon dioxide absorption amount and absorption rate of N-methyldiethanolamine are improved; the activating agent is added into the energy-saving corrosion-inhibition type decarburizing agent, so that the absorption rate of the decarburizing agent on carbon dioxide can be effectively improved, and the desorption energy consumption of the carbon dioxide is reduced; and the corrosion inhibitor is added, so that the corrosion of metal equipment can be effectively reduced.
