Abstract

Dimethyl Ether (DME) is an alternatives energy that can be synthesized through a direct process from syngas (CO and H2) with utilizing Cu-ZnO/Al2O3-HZSM-5 as a hybrid catalyst. Direct synthesis DME technology is relatively new technology by utilizing syngas that can be derived from gasification of biomass and coal. The purpose of this study is to obtain the catalyst composition with the most optimal performance. Catalyst is prepared with co-precipitation method through variation ratio of the catalyst Cu-ZnO-Al2O3 that be mixed with HZSM-5. The component Cu-ZnO-Al2O3 catalysts were characterized using XRD, EDX, BET, and FE-SEM. Test of catalyst activity carried out with fixed bed reactor at temperature 260°C and pressure 20 bar using ratio syngas (H2: CO = 2). The products of reaction were analyzed with GC-FID (Product DME) and GC TCD (CO conversion). From the result of catalyst characterization were identified that hybrid catalyst CZA A shown better characteristic compared other catalyst. In the catalyst activity testing, the highest yield was obtained for hybrid catalyst CZA A the value is 15.03%and CO conversion is 28.15%.
