Methanol dehydration using a solid catalyst is a common technology to produce DME. In this research, a catalyst γAl2O3 prepared in our laboratory has been characterized. This catalyst had a surface area of 194.4 m2/g, a total pore volume of 0.55 mL/g, and an average pore diameter of 112, 3 Ȧ. This catalyst had medium and high acidity sites. Activity tests of this catalyst were carried out in a fixed bed reactor at temperatures of 240, 260 and 280°C. The gas flow rates were related to the gas hourly space velocity of 1500, 2142 and 3000 h-1. Experimentally, the conversions of methanol were closed to that of thermodynamic conversions, i.e about 90% depending on the reaction temperature. The outlet gas was found to contain H2 up to 2% indicating that there were side reactions besides the dehydration of methanol to DME.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This study is a part of Doctoral Research at the Department of Chemical Engineering, ITB.
