摘要

Provided are a method for synthesizing mordenite having mesopores and micropores, and a product and application thereof. The method comprises precrystallizing, at 50°C-120°C for not less than 2 hours, a mixture containing a templating agent, a silicon source, an alkali source, and water, then adding an aluminum source, and then crystallizing at 120°C-220°C for not less than 12 hours. The method does not require the addition of a mesoporous templating agent, and the obtained mordenite has both micropores and mesopores; the obtained mordenite has excellent performance in respect of adsorption and catalysis, and may be applied to dimethyl ether carbonylation reaction catalysts.
