The production of hydrocarbons via a synthetic route has been extensively studied by Mobil in its MTG process. The focus of much of this research was centered on gasoline range hydrocarbons from a methanol feedstock. Since its development, a novel, more efficient hydrocarbon synthesis process has been developed by the University of Akron using dimethyl ether; namely UA/EPRI DME-to-Hydrocarbon process (DTG). The DTG process has many distinct advantages over Mobil`s methanol based MTG process. Key features of the DTG process include enhanced per-pass conversion and volumetric productivity, lower heat duties, extended catalyst life, and higher selectivity to hydrocarbons. Product distributions for the DTG process are similar to the MTG process. In an effort to satisfy the industries growing need for olefins, it became necessary to determine which set of operating parameters affected the olefinic fraction of the product gas. Product distributions were determined for various levels of DUE weight hourly space velocity, as well as reactor temperature and pressure. The experimental investigation took place in a fixed bed micro-reactor. Capable of holding 1--15 g catalyst, the fixed bed was designed to obtain kinetic/mechanistic data for hydrocarbon production. Product gas analysis was performed using an external GC standard method.
