In support of a reactive distillation experimental program, bench scale experiments were conducted for the production of high molecular weight olefins via metathesis. A fixed bed rhenium oxide (Re2O7) catalyst on a gamma-alumina support was utilized to study the reaction of C-6, C-8, and C-10 olefins to form light and heavy olefin products. Initial experiments determined the impact temperature and weight hourly space velocity (WHSV) had on the reactivity of three different a- olefins. The investigated temperatures and WHSV were conditions that encompassed the anticipated reactive distillation column reactor zones temperatures and WHSV. All of these runs displayed high conversions, low selectivities, and significant secondary isomerization coupled with subsequent metathesis. This isomerization compromised the ability to make any quantitative assessments on the reactivity of olefins with respect to temperature, flow rate, and carbon number in the feed. However, it was concluded that there was a possible optimal condition of a low flow and low temperature. Additional experiments revealed the impact temperature had on conversion and selectivity of C-8 and C-10 a-olefins. These experiments concluded that between an ambient temperature condition and 60 degrees C, there was a moderate conversion of the feed and a relatively high selectivity to the primary liquid product. However, above 60 degrees C, there was a step change in the amount of isomerization, which resulted in significantly higher conversions and significantly lower selectivities. An experiment with a temperature ramp over time located this step change in isomerization by suggesting that this temperature occurred between 60 and 70 degrees C.
