Dimethyl ether (DME) has been considered a potential and promising energy alternative for petroleum subproducts due to its good burning characteristics, and to its high cetana content which is superior to that of diesel. Furthermore, DME can be considered a cleaner fuel than diesel. DME can be produced by dehydration reaction of methanol by using solid catalysts in catalytic reactions. This study shows an analysis of the performance of Al62,2Cu25,5Fe12,3 quasicrystalline alloy as catalyst for dehydrating methanol to produce DME. These quasicrystalline alloys are stable at high temperatures, show a low thermal conductivity and exhibit a fragile nature, which turn them to be easily crushed. Also, their activity is not affected by water. In this research it were used the following special measurements: (i) X-Ray Diffratometry (XRD) for analyzing the phases evolution of the alloys; (ii) S.. View More»
