Maximizing paraffin to olefin ratio employing simulated nitrogen-rich syngas via Fischer-Tropsch process over Co3O4/SiO2 catalysts
Abstract
<p>The optimization of cobalt oxide (Co<sub>3</sub>O<sub>4</sub>) loading on silica for the low-temperature Fischer-Tropsch (LTFT) synthesis process employing simulated nitrogen-rich syngas (50 vol%) to produce highly paraffinic biodiesel is studied. Four different amounts of Co<sub>3</sub>O<sub>4</sub> varying from 15 to 36 wt% were loaded on silica in order to examine the catalytic performance of Co/SiO<sub>2</sub> catalysts. The supported catalysts were characterized using XRF, nitrogen physisorption, XRD, TPR, DRIFT and SEM fixed with EDS analysis. The performances of the catalysts were examined in a single channel fixed bed reactor employing simulated nitrogen-rich syngas (CO:H<sub>2</sub>:N<sub>2</sub> = 17:33:50 vol%). The reactor was operated at P = 20 bar, T = 237 °C and WHSV = 3.0 Nl/h.g<sub>cat</sub>. The active site concentration was maximized by (i) utilizing all the available surface area of the sphere's porous support, (ii) using ethanolic impregnation solution to hinder sintering of Co<sub>3</sub>O<sub>4</sub> phases due to presence of ethoxyl groups, and (iii) connecting oxide crystallites to the neighbouring pores by increasing the active metal content. As a result, the production of heavy hydrocarbons per unit of time was maximized with 36 wt% cobalt loading on silica (CO conversion and C<sub>5+</sub> selectivity were 87.65 and 81.78 mol%, respectively, and also paraffin: olefin ratio was 98:2).</p>
