The present disclosure discloses an ethylene degradation catalyst and a preparation method and a use thereof.

Ethylene degradation catalyst and preparation method and use thereof

The present invention relates to a method for preparing a solid amine gas adsorption material. The method synthesizes a porous solid amine gas adsorption material that loads organic amine evenly. In the method, a certain amount of acidic gas is introduced while organic amine molecules are introduced into a silicate solution as template agents, which not only makes sizes of SiOpore channels homogeneous, but also makes organic amine molecules highly evenly distributed on a surface of SiO. In addition, the acidic gas protects &#x2014;NHgroups of organic amine, and avoids &#x2014;NHadhesion inactivation due to hydrogen bonding during the synthesis process of the material. The present invention also relates to a method for preparing a solid amine gas adsorption material after obtaining a silicate solution from fly ash. The solid amine gas adsorption material prepared has more stable and effective gas adsorption performance.

The present invention discloses a method for preparing a soda-lime-silica glass basic formulation and a method for producing soda-lime-silica glass, comprising the steps of: pre-desiliconizing silicon-containing powdery industrial waste with a sodium hydroxide solution; introducing carbon dioxide for carbonation decomposition, and filtering to obtain a silicic acid precipitate and a sodium carbonate solution; drying the silicic acid precipitate to obtain silicon dioxide; adding lime milk into the filtered sodium carbonate for causticization, and filtering to obtain a sodium hydroxide solution and a calcium carbonate precipitate; drying the calcium carbonate precipitate; using said silicon dioxide and part of the calcium carbonate and adding sodium oxide. The present invention further discloses a method for extracting aluminum from coal ash for co-production of soda lime glass, which uses silicon dioxide obtained from alkali dissolution and desiliconization of coal ash and calcium carbonate generated from causticization as main raw materials. The method for extracting aluminum from coal ash for co-production of soda lime glass according to the present invention integrates and optimizes a process of extracting aluminum from the coal ash, has a high material and energy utilization rate, good quality of co-product glass, and high added value, and can greatly improve economical efficiency of aluminum extraction of coal ash.
