Description

Method for preparing high-micropore NaY molecular sieve with assistance of alcohol terminated compound and application of high-micropore NaY molecular sieve
Technical Field
The invention belongs to the technical field of material preparation and environmental purification, relates to a preparation technology and application of a NaY molecular sieve adsorbent, and in particular relates to a method for preparing a high-micropore NaY molecular sieve with the assistance of a terminal alcohol compound and a method for deeply removing SO (sulfur-containing oxygen) by using the same 2 Application of the aspect.
Background
Sulfur dioxide (SO) 2 ) Is a byproduct of the combustion of the fuel that is vented to the atmosphere. The flue gas typically produced contains about 500-3000ppm SO 2 Not only greatly aggravates air pollution and is easy to induce respiratory diseases of human bodies, but also seriously hinders industrial production. Each plant places stringent requirements on deep desulfurization due to SO 2 Is small in the absorption capacity and removes SO at low concentration 2 Deep desulfurization is a great challenge.
Conventionally, limestone methods (Fuel, 2015, 144, 274-286) commonly used in industrial wet flue gas desulfurization are effective in removing SO 2 But generates a lot of waste water and residues, corrodes the pipeline, and requires further treatment. The ionic liquid solvents (chem. Eng. J., 2015, 265, 249-258) are effective in absorbing SO 2 The secondary solid waste is not accumulated, but equipment is corroded in the regeneration process, and the solvent is easy to lose, so that the process is severely limited fundamentally. In combination, dry desulfurization is currently the most practical, economical, and effective technique for eliminating sulfur-containing contaminants industrially. A number of solid adsorbents including metal oxides, activated carbon and zeolites have been developed for capturing sulfur compounds. Metal oxide (j. Hazard. Mater., 2018, 342, 326-334.) adsorbents are expensive and produce additional by-products of unusable metal sulfate. The high regeneration costs of activated carbon (Energy Fuels, 2021, 35, 8102-8116) limit its development. In general, these techniques are economical and cyclicThe problem of environmental sustainability is seriously affected. Therefore, there is an urgent need to develop adsorbent materials for high-efficiency, reversible SO that are excellent in adsorption performance, renewable, and easy in product recovery 2 Capturing.
Zeolites have been the leading edge of many studies. The zeolite has a large specific surface area and an adjustable porosity, and can effectively screen and separate mixed gas through the difference of adsorption and diffusion. Meanwhile, the zeolite has higher adsorption performance, excellent reusability, continuous regeneration capability and relatively lower reaction temperature. The NaY molecular sieve is a silicon aluminum phosphate crystal, and has wide application in the fields of petrochemical industry, energy sources, environmental management and the like due to the unique crystal structure, uniform and regular micropore channels, large specific surface area and excellent thermal stability. The NaY zeolite has wide pore distribution, large pore diameter and small mass transfer resistance, is an adsorbent with great potential, and is favorable for realizing low-concentration SO 2 High-efficiency adsorption and high-cycle adsorption regeneration. In general, the templating agents required to prepare zeolites are expensive, and most zeolites remain in the laboratory stage and are not commercially viable.
At present, it has been reported that NaY zeolite is prepared by using a surfactant, for example, a surfactant is added in the synthesis of a directing agent in patent CN 103449469A, so that NaY zeolite with better stability is prepared, and N, N-diethylamino-N-hexadecyl-N- (3-methoxypropane) ammonium iodide and N, N-dimethyl-N- [3- (trimethoxy) propyl ] octadecyl ammonium chloride (TPOAC) amphiphilic organosilane are respectively disclosed as templates for synthesizing Y zeolite. However, the method uses expensive organosilane as a template agent, the consumption of the organosilane is large, and the crystallization time is long, which can definitely greatly increase the synthesis cost of the hierarchical pore Y molecular sieve, and is not beneficial to the industrial application and popularization of the hierarchical pore Y molecular sieve. Therefore, the rapid synthesis strategy of the NaY molecular sieve which is simple and convenient to design and green is very critical.

The initial gel was transferred to a Telfon kettle liner, the kettle was placed in an oven, and hydrothermal crystallized at 100℃for 12 h. After the crystallization is finished, the crystal is completely crystallized,the solid product was washed, filtered, and dried at 80 ℃ for 8 h, and the molecular sieve sample prepared was designated as private Y.
