Abstract

Dimethyl ether (DME) is an industrially important intermediate, as well as a promising clean fuel, but the effective production through traditionally consecutive steps from syngas to methanol and then to DME has been hindered by the poorly organized structure of the conventional physical mixture catalyst. Here a Meso structured Silica Alumina support on which the catalyst Cu-ZnO has been impregnated was proposed to accomplish the DME direct synthesis from syngas. The catalysts has been characterized by techniques like BET surface area (N2 adsorption studies), Temperature programmed Desorption (NH3- TPD), Temperature programmed Reduction (H2-TPR) and FTIR. Experimental set up and procedure for the synthesis has been discussed. The results obtained in these characterizations has been reported and analyzed.
