Abstract
The invention belongs to the technical field of industrial solid waste recycling and molecular sieve materials, and particularly discloses a method for synthesizing MOR zeolite. The fluorine-containing silicon slag generated in the fluorine chemical industry is converted into the high-performance MOR zeolite aiming at the dual problems that the traditional zeolite synthesis raw material cost is high and the fluorine-containing industrial waste slag is difficult to treat. The specific method comprises the following steps: mixing fluorine-containing silicon slag with an alkaline solution to obtain aluminosilicate gel; mixing the aluminosilicate gel with a sodium source, performing aging, and then performing crystallization reaction to obtain MOR zeolite; wherein the fluorine-containing silicon slag is waste slag generated in the production process of anhydrous hydrogen fluoride; the alkaline solution is a solution obtained by dissolving sodium metaaluminate in deionized water; the sodium source is sodium hydroxide. According to the invention, the coupling of hazardous waste recycling and high-value material preparation is realized, the process flow is simple, the preparation cost is low, and the synthesized MOR zeolite is suitable for reactions such as catalytic cracking, isomerization, dimethyl ether carbonylation and the like and adsorption of heavy metals and harmful gases.
