Problems solved by technology

At present, in all adsorption technologies, the most widely used adsorption material is amine solvent. The advantages of this type of adsorption material are high adsorption capacity and good selectivity, but the state of amine as a liquid itself has high renewable energy consumption, which is harmful to equipment. It has disadvantages such as strong corrosion, and is only suitable for the absorption of medium or low concentration of carbon dioxide, so the development of a new material for absorbing environmental carbon dioxide has a good market prospect

Embodiment 1

[0041] First, wash 3 times with absolute ethanol to pretreat the ZSM-5 molecular sieve, then add 2 mL of ethanolamine to 50 mL of deionized water, stir for 0.5 h to mix well, take 4 g of ZSM-5 molecular sieve after treatment, add the above solution and stir for 2 h and Ultrasonic impregnation for 1h. Filter and dry at 120°C for 10 h, and the amino functionalized adsorption material prepared by this method is marked as Z-1.

Embodiment 2

[0043] First wash 3 times with absolute ethanol to pretreat the MCM-41 molecular sieve, then weigh 2g of semicarbazide and add it to 50mL of deionized water, stir for 0.5 h until the mixture is uniform, take 4g of the treated MCM-41 molecular sieve and add it to the above solution and stir for 2h And ultrasonic impregnation for 1h. Filter and dry at 120°C for 10 h. The amino functionalized adsorption material prepared by this method is labeled as Z-2.

Abstract

The invention discloses a molecular sieve material for efficiently adsorbing environmental carbon dioxide and a preparation method thereof. The molecular sieve material is composed of molecular sieves and one or more organic amines linked by a chemical bonding form, wherein the organic amine is bonded to an inner and outer surface of the molecular sieve, and the molecular sieve material for efficiently adsorbing environmental carbon dioxide removes carbon dioxide from the environment to purify the air. The molecular sieve can be a ZSM-5 molecular sieve, an MCM-41 molecular sieve or an MOR molecular sieve. The organic amine can be one or more of ethanolamine, methyldiethanolamine, triethanolamine, triethylene tetraamine, tetraethylene pentamine, polyethylene imine, polyacrylamine or semicarbazide.

Description

technical field [0001] The invention belongs to the field of material preparation, in particular to the field of adsorption material preparation, in particular to a molecular sieve material for efficiently adsorbing environmental carbon dioxide and a preparation method thereof. Background technique [0002] CO in the global atmosphere 2 The concentration has increased rapidly since the industrialization era, especially in the past ten years in the atmosphere of CO 2 Concentrations increase very rapidly due to atmospheric CO 2 Increased concentrations will lead to a 5°C increase in global temperature and sea level rise. The increase of greenhouse gases has caused the global temperature to rise, which has caused a series of problems such as drought, flood, sea level rise, extreme climate, etc., which has seriously affected the ecological balance of the earth and the future living environment of human beings, and has also had a negative impact on economic development.
