The effect of cage size on selectivity in the methanol-to-olefins reaction was studied. AFX, CHA and LEV frameworks were synthesized with the same silicon/aluminum ratio and tested. Ethylene selectivity increased with a smaller cage. Propylene selectivity was highest with the CHA cage. The AFX structure had the worst lifetime
