- Abstract
- MCM-22 zeolite containing vanadium atoms either at structural or at ion-exchange positions was synthesized and tested in propane oxidative
dehydrogenation (ODH) reaction in a fixed bed reactor, at temperatures between 340 and 5608C. Acidity of these materials, as well as of similar
materials that did not contain vanadium, was characterized by ammonia temperature programmed desorption (TPD-NH3). Vanadoaluminosilicates
contain a higher number of acid sites, which present higher acidity in relation to the aluminosilicates. They also presented better performances in
propane ODH, as they lead to higher values of conversion without loss of selectivity. Ion-exchange with alkaline ions leads to a decrease in cracking reactions, which are caused by strong Brønsted acid sites. (literal)
