WebSynthesis of a mordenite-like zeolite from reaction mixtures of composition 2.5R ·. (2.2-7.3)Na2O · Al2O3 · (12-40)SiO2 · (300-1200)H2O, where R is monoethanolamine, was studied. The crystallization conditions under which mordenite with a SiO2/Al2O3 ratio of 13 to 22 can be synthesized were determined. WebLayered MCM-22 (P) was synthesized in the presence of hexamethonium (HM) cations. Compared to zeolite EU-1 (EUO-type structure), which crystallizes in similar conditions, its formation is favored at high HM …

WebUOP and CEPSA developed the DETAL process for fixed-bed alkylation,which was commercialized in 1995 based on solid acid catalyst. The process includes the alkylation reaction operation and the catalyst washing regeneration operation for each 24 h mutual switching[2-3]. Mordenite has been extensively evaluated for the synthesis of LAB. WebDec 20, 2024 · Most mordenite syntheses use a Na 2 O/SiO 2 /Al 2 O 3 system, where the hydrated Na + cation can be a templating agent. Mordenite zeolite has several … tag number on ez pass
