Different acid catalysts (silicoaluminophosphates (SAPOs) -34, −18, and − 11, HZSM-5 zeolite) were tested as components of In2O3-ZrO2/acid tandem in the direct synthesis light olefins by hydrogenation CO2, CO their mixture. The conversion yield selectivity evidence that presence large amount strongly acidic sites SAPO-34 favors extent reaction mechanism with methanol intermediate, minimizing se...

The methanol-to-olefin process is a showcase example of complex zeolite-catalyzed chemistry. At real operating conditions, many factors affect the reactivity, such as framework flexibility, adsorption of various guest molecules, and competitive reaction pathways. In this study, the strength of first principle molecular dynamics techniques to capture this complexity is shown by means of two case...
