Quality improvement of bio-paraffin mixtures

• Quality improvement of bio-paraffin by isomerization was studied to produce biogasoil.
• Reaction rates and activation energy of isomerization were investigated over Pt/SAPO-11 catalyst.
• The effect of fatty acid content of feedstock on isomerization reactions was demonstrated.
• Industrial application of favourable results and excellent quality products were presented.

Quality improvement of bio-paraffin by isomerization was studied in presence of fatty acid over Pt/SAPO-11 catalyst in order to produce second generation biogasoil. The reaction rates and activation energy of the isomerization having high importance in both reactor design and process control were determined. The increase of the fatty acid content of feedstock significantly decreased the rate of isomerization of bio-origin octadecane, but did not affect the activation energy being 143 ± 3 kJ/mol. Industrial application of the favourable results and the excellent quality properties of end products were also demonstrated.
