Abstract

A method for preparing a decarburization absorption liquid modifier, which is characterized by including the following steps: first, use AlCl3, FeCl3, Ni(NO3)2, Ba(NO3)2 in a weight ratio (1-2): (0.1 -0.3): (0.2-2): (2-5) Dissolve in water, the weight ratio of total solids to water is 5%-25%, after dissolution, pour ethanol with a concentration of 40-60%, the volume of the solution occupied by ethanol The ratio is 10%-20%. After stirring evenly, add ammonia dropwise while stirring until pH=10, then transfer to the autoclave, heat to 240-260°C and keep for 4-6 hours, then filter and bake at 100-110°C. Dry to obtain nano-sized particles; secondly, immerse the nano-sized particles obtained above in a 2-piperidine ethanol solution with a concentration of 20%-35%, and the weight ratio of the nano-sized particles is 3%-10%. Stir and introduce ozone aeration during the process. The ozone concentration is greater than 10g / m3. According to 1L solution, the flow rate is 140-160mL / min. The impregnation process lasts for 6-10 hours, and then filtered and dried at 100-110℃. It can be roasted at 240-260℃ for 1.5-2.5 hours. The invention can improve the CO2 absorption capacity and transport capacity of the organic amine glue carbon agent, and significantly improve the flue gas decarbonization effect.

Description

technical field [0001] The invention relates to a decarburization technology, in particular to a method for manufacturing a modifier capable of improving the decarburization performance of a decarburization solution, specifically a decarburization absorption that can be used at normal pressure and significantly improve the decarburization efficiency Preparation method of liquid modifier. Background technique [0002] During the combustion of fossil fuels and the degradation of organic matter, large amounts of CO are produced 2 The gas is released into the atmosphere and becomes the main source of greenhouse gas emissions. During the combustion of fossil fuels, CO 2 It is emitted in the form of flue gas, while in the process of organic matter degradation, CO 2 Often converted to a component of biomass gas, such as biogas. In recent years, with the deepening of greenhouse gas emission reduction and resource recycling, the application demand for decarbonization technolo...
