The structure of the as-made, hydrated form of ECR-40C, synthesized in the presence of (2-hydroxyethyl) trimethylammonium (HTMA) ions as an organic structure-directing agent (OSDA) and 2 wt% (relative to alumina in the synthesis mixture) of aluminosilicate zeolite UZM-22 with the MEI topology as seeds, has been determined using synchrotron powder X-ray diffraction and Rietveld analyses. Two dif...

• ERI-type molecular sieves enhance ethylene selectivity in MTO . Acidity significantly influences ethylene-to-propylene ratio materials. Changes acidity alter hydrocarbon-pool species concentration and composition. Low acid site densities hinder the formation of aromatics (thus, ethylene) ERI. (SSZ-98, UZM-12, zeolite, SAPO-17) are synthesized with varying Si/Al = 5–9 Si/T-atoms 0.034–0.12 usi...
