Production of Bioparaffins from Natural Triglycerides

The production possibilities of gasoil boiling range mixtures of paraffins were investigated over different catalysts as a function of the process parameters using different natural triglycerides. At the favourable operational parameters (T: 360-380°C; p: 60-80 bar; liquid hourly space velocity (LHSV): 1.0-2.0 m feedstock/ m catalyst · h; H2/HC: 450 Nm/m) the yield of paraffin mixtures increased in the order of NiW/Al2O3 < NiMo/Al2O3 << CoMo/Al2O3. In the best cases the yields of paraffins reached 7585% of the theoretical values. These compounds are excellent fuels of Diesel engines (cetane number: 89-92) using them as pure fuels or blending components.
