Abstract:
The production possibilities of gas oil boiling-range mixtures of paraffins were investigated over different catalysts as a function of the process parameters using different natural triglycerides. Under favorable operational parameters (T: 360–380 °C; p: 60–80 bar; liquid hourly space velocity (LHSV): 1.0–2.0 cm³ of feedstock/(h∙cm³ of catalyst)), the yield of paraffin mixtures increased in the order NiW/Al₂O₃ < NiMo/Al₂O₃ << CoMo/Al₂O₃. In the best cases, the yields of paraffins reached 75–85% of the theoretical values. These compounds are excellent, environmentally sound fuels for diesel engines (cetane number: 89–92) and could be used either as pure fuels or as blending components.
