Abstract
The CatLiq® process is a second generation catalytic liquefaction process for the production of bio-oil from WDGS (Wet Distillers Grains with Solubles) at subcritical conditions (280-350 oC and 225-250 bar) in the presence of a homogeneous alkaline and a heterogeneous Zirconia catalyst. In this work, the bubble point pressures of a selected model mixture (CO2 + H2O + Ethanol + Acetic acid + Octanoic acid) were measured to investigate the phase boundaries of the CatLiq® process. The bubble points were measured in the JEFRI-DBR high pressure PVT phase behavior system. The experimental results were presented for the temperatures between 40 oC and 75 oC. The results were correlated by the PSRK (Predictive Soave-Redlich-Kwong) model using Huron-Vidal first-order mixing rule of Michelsen coupled with the modified UNIFAC model. The average absolute deviation between the experimental and predicted data is 8.7% in the selected model mixture.
