Abstract

Highlights: The biodiesel production was investigated using marine microalgae Nannochloropsis salina. CaO nanocatalyst obtained from egg shell delivers high catalytic performance. The biodiesel production was optimized by ANN model. 86.1% of biodiesel yield was achieved under optimized conditions. The GCMS analysis was confirmed the ester derivatives found in produced biodiesel. Abstract: In the present investigation, calcium oxide solid nanocatalyst derived from the egg shell and Nannochloropsis salina were used for the production of biodiesel. The morphological characteristics and functional groups of synthesized nanocatalyst was characterized by SEM and FTIR analysis. Process variables optimization for biodiesel production was studied using RSM and ANN. The R 2 values for RSM and ANN was found to be 0.8751 and 0.957 which showed that the model was significantly fit with the experimental data. The maximum FAME conversion for the synthesized nanocatalyst CaO was found to be 86.1% under optimum process conditions (nanocatalyst amount: 3% (w/v); oil to methanol ratio 1:6 (v/v); reaction temperature: 60 °C; reaction time 55 min). Concentration of FAME present in biodiesel was identified by GC–MS analysis.
