A face centered composite design of experiments was employed to study and optimize the effect of applied pressure, pressing temperature and moisture content on oil recovery. A quadratic polynomial model was generated to predict oil recovery and was found to cover 98% of the range for the factors studied, namely 10-20. MPa applied pressure, 60-90. °C pressing temperature and 3-5% (w.b.) moisture content. Among the process parameters studied, pressing temperature had the most significant effect on the recovery followed by applied pressure and quadratic of moisture content. Model validation experiments show good correspondence between actual and predicted values. The optimal extraction condition for oil yield within the experimental range of the variables researched was at 19. MPa applied pressure, 90. °C pressing temperature, and 3.8% (w.b.) moisture content. At this condition, the yield of oil was predicted to be 87.8%.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Composite designs,Hydraulic press,Jatropha curcas l,Oil extraction,Response surface methodology[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Face-centered composite design,Hydraulic press,Jatropha curcas L.,Oil extraction,Process optimization,Response surface methodology[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors are grateful to the Koninklijke Nederlandse Akademie van Wetenschappen, Scientific Programme Indonesia – Netherlands (SPIN-KNAW), The Netherlands for the financial support.
