Norwegian University of Life Sciences11 Conclusion The calcium oxide catalyst derived from waste Mussel shells was found to present decent activity to acclerate the transformation of jojoba oil. The alcoholysis reaction performed at 85 ºC for 600 min using butanol-to-oil molar ratio of 12.8:1, 16 wt. % catalyst amount and 350 RPM stirring intensity resulted in % jojoba oil conversion. However, the appliance of further elevated amount of catalyst and butanol resulted in decline of jojoba oil conversion. The maximum jojoba oil conversion of % was achieved when the butanolysis reaction time was extended till 1800 min. The appropriate utilization of the value-added chemicals and biofuel generated from Jojoba oil and its derivatives could be beneficial from the biorefinery perspective.
