Acid silicoaluminophosphate SAPO-34 catalysts with a chabasite-related (CHA) structure were tested for the oxidative dehydrogenation of ethane in the temperature range 550-700 °C achieving very interesting catalytic performances (about 70% C2H4 selectivity at 45% ethane conversion) which were related to both Lewis and Brønsted acid sites, as found by a NH3-TPD study.
Acid SAPO-34-based microporous catalysts with chabasite structure have been tested for the oxidative dehydrogenation of ethane in the temperature range 550–700°C. Pure acid and La/Na-containing samples were monitored and very interesting catalytic performances were achieved at 550–700°C (75–60% C 2 H 4 selectivity and 5–30% ethane conversion) with respect to those reported for both...
