2019 AIChE Annual Meeting

Reactions in Near-Critical and Supercritical Fluids
Friday, November 15, 2019 - 12:47pm to 1:04pm
In this talk, we will report the activation energies involved in the production of lighter products, such as C4, C6, and C8, and also heavier hydrocarbons, such as C10, C12, and C14. Furthermore, we will discuss a reaction network based on the product distribution and reaction order involved in the production of each one of the products under supercritical ethylene conditions. The effects of weight hourly space velocity (WHSV) on the product selectivity and conversion will help to validate the pathway proposed and identify new pathways not identified before. A parallel solubility study will be reported to elucidate the products formed by the desorption of coke from the catalyst from the products formed due to the solubility of coke in the supercritical ethylene. The results obtained will be compared with the kinetic under subcritical conditions and the differences will help to highlight the advantages of using supercritical fluid conditions on the ethylene oligomerization over the Ni-H-Beta catalyst.
