Abstract
An aluminosilicate zeolite may have a molar ratio of Si to Al of about 3 to about 10, a monoclinic space group C2/m with unit cell dimensions of a of 13.6 Å+/−5%, b of 21.7 Å+/−5%, c of 6.7 Å+/−5%, and β of 93°+/−3°, 12-ring pores along a c-axis having dimensions of 7 Å+/−5% by 6 Å+/−5%, and 8-ring pores along an a-axis having dimensions of 3 Å+/−5% by 3 Å+/−5%. Said aluminosilicate zeolites may be useful in hydrocarbon conversion processes, selective catalytic reduction of NOx, CO2 and/or N2 adsorption, carbonylation reactions, and the monoalkylamine and dialkylamine syntheses.
