Abstract

Dimethylether (DME) which is a very attractive synthetic transportation fuel alternate is synthesized by the dehydration reaction of methanol over nafion as the catalyst. The objective is to test the activity of this catalyst in methanol dehydration reaction. Experiments carried out in a vapor phase flow reactor in a temperature range of 120-220 degrees C and with a space time of 1.35 s.g/cm(3) showed quite high activity of Nafion to produce DME, giving conversion values of about 0.4 at 220 degrees C. An increase in temperature caused an increase in DME selectivity (reaching to one over 200 degrees C) and a decrease in formaldehyde selectivity.
