| Resumen | Transcripción del resúmen publicado por el autor: In an attempt to understand the textural and acidic properties of zeolites on the methanol conversion and product selectivities, three zeolites, ferrierite, clinoptilolite, and SAPO-34, are studied. Temperature-programmed desorption of ammonia (NH3-TPD) indicated the presence of more weak acidity on ferrierite and clinoptilolite compared to the considerable strong acidity on SAPO-34. At 250 °C, all three samples exhibited comparable methanol conversions, but relatively lower dimethyl ether (DME) and higher light olefins are observed on SAPO-34. Ferrierite and clinoptilolite samples exhibited high selectivity for the formation of DME even at higher reaction temperatures (400 °C), while the product shifted from DME to light olefins with an increasing reaction temperature on SAPO-34. Especially, ferrierite, owing to its mild acidity and small pore size, is found to be a good catalyst for the methanol conversion to DME at 250 °C without significant deactivation for 100 h time on stream. |
