The influence of hydrogen on the catalytic deoxygenation fatty acids was investigated in semibatch reactor over a mesoporous 5 wt % Pd/C (Sibunit) catalyst. Transformations model acid (lauric acid) and reaction intermediates aldehyde lauryl alcohol) were performed under inert rich atmosphere. Analysis liquid gas phases mixture revealed that different reactions occurred depending content A higher yield hydrocarbons (59 mol %) obtained pressure compared to an experiment argon where reached 39...
Catalytic deoxygenation of tall oil fatty acids (TOFAs) was investigated over 1 wt % Pd/C Sibunit, which is a synthetic mesoporous carbon. The reactions were performed in semi-batch reactor using dodecane as solvent under 17 bar total pressure. main studied parameters the reaction temperature, initial concentration TOFA, effect atmosphere, and metal loading. temperature ranges 300–350 °C 0.15–0.6 mol/L, respectively. conversion increased, expected, with increasing temperatures decreasing...
Deoxygenation of dilute and concentrated stearic acid over 2% Pd/C beads was performed in a continuous reactor at 300 °C 20 bar pressure Ar or 5% H2/Ar. Stable operation obtained H2 atmosphere, with 95% conversion 10 mol % dodecane 12% pure acid. Deactivation took place H2-deficient gas probably as result the formation unsaturated products coking pore system. Transient experiments step changes were performed: 1 h required for change to be visible liquid sampling, whereas steady states...
Single step upgrading of biomass-derived short carboxylic acids to a jet fuel additive.
We have studied the single-step catalytic conversion of biomass-derived aliphatic carboxylic acids to linear olefins via tandem hydrogenation/dehydration reactions. Hexanoic acid was converted a mixture hexenes (92.0% selectivity) over silica–alumina supported Cu nanoparticles. Remarkably, we observed rapid selectivity switch 99.8% hexane once were fully consumed, with similar results using butanoic derived from biomass consolidated bioprocessing. Based on intermediate, desorption, and in...
The acetate fraction is the fourth most abundant by weight in many plant species and can be easily extracted as acetic acid high yields. We have previously shown that obtained from steam pretreated beech wood could upgraded a single step into mixture of cycloalkenes aromatics suitable for use an aviation fuel additive. In this work, we developed validated reaction network process performing detailed kinetic study. Specifically, model along with experimental data was used to estimate...
