Investigation of parametric optimisation for the extraction of rice bran oil with the aid of ultrasound and its synthesis to biodiesel

Improvisation of the biodiesel production using low-cost feedstock and process optimisation is perfect measure for mitigation high cost associated with process. In this current study, we are focussing on extraction rice bran oil (RBO) which mainly considered underutilised waste material synthesis biodiesel. Solvent RBO was performed aid ultrasound study various parameters were exhibited design experiment by Taguchi model. The highest efficiency obtained at S/R ratio: 4:1 (ml/g), Agitation speed: 150 (rpm), time: 60 (min), Size range: 427.5 (micron), Sonication time (min): 15 (min) Power level: 70 (KW). It observed that ultrasound-assisted produced better quality than conventional Soxhlet. Secondly, esterification sulphuric acid as catalyst parametric optimization enhancement yield L9 orthogonal array. key factors viz. agitation speed 1000 rpm, methanol to ratio (M/O) 10:1and reaction temperature °C; found be favourable attainment maximum
