Biodiesel production by enzymatic process using Jatropha oil and waste soybean oil

摘要: In this study, non-edible Jatropha oil and postcooking waste soybean were utilized for enzymatic biodiesel production. The process was optimized by using a statistical method. addition, novel continuous co-immobilized Rhizopus oryzae Candida rugosa lipases developed. optimum conditions the batch determined to be reaction temperature of 45oC, an agitation speed 250 rpm, 10 wt% water, 20% immobilized lipases. A conversion about 98% at 4 h could achieved production oil, while 97% from oil. packed bed reactor charged with employed consisted jacketed glass column (ID 25 mm × 130 mm), in which 45°C maintained water circulation. maximum 80% 24 flow rate 0.8 mL/ min process, whereas two-stage 90% 72 attained 0.1 mL/min.
