Abstract

Di–Methyl Ether (DME) is the simplest ether compund with chemical formula
CH3OCH3
or also known as methyl ether or wood ether, whichcan be produced
two ways namely direct–process and indirect–process. Direct–process is the
process of syngas (H
2+CO) formation which can be produced via gasification of
coal / biomass or partial oxidation of natural gas,and then synthesized into DME.
While the indirect–process is a process that begins with MeOH manufacturing,
followed by MeOH dehydration in a separate reactor synthesized into DME.
Utilization of energy resources means increased economical value and as an
effort to reduce dependence on fosil fuels as well as solves the environmental
pollution problems. Until now, most DME is made by indirect–process via the
catalytic dehydration of MeOH in the fixed–bed reactor (a simple process and low
capital investment) is licensed by Lurgi, Haldor–Topsoe, Mitsubishi Chemical
Gas (MGC) and Toyo Engineering Corporation (TEC), while the direct–process
technology with the high efficiency proposed by Haldor Topsoe, JFE and Air
Products Chemicals Inc. is under development stage in Japan, USA as well as
China, and so far not fully yet commercial. This paper will discuss about the
technology of DME direct–process synthesis from syngas through coal/biomass
gasification or natural gas partial oxidation process as an environmentally friendly
alternative fuel.
