Production and optimization of biodiesel from parsley seed oil using KOH as catalyst for automobiles technology

The production and optimization of biodiesel from a novel feedstock (parsley seed oil) using catalytic potassium hydroxide were investigated in this work with respect to the influence of the parametric reaction: temperature of reaction, time, and the ratio of alcohol-to-oil on the biodiesel yield. The best optimized conditions to generate parsley biodiesel were investigated with the aid of response surface methodology design tool while the analysis of variance showed that the reaction parameters employed had a significant influence on the yield of biodiesel from parsley. The biodiesel percentage yield of 98% was the optimum yield achieved from the experiment conducted with reaction conditions of 60 degrees C, 30 min, and 6:1 for the temperature of the reaction, time of reaction, and the ratio of alcohol-to-oil respectively while the biodiesel percentage yield of 98.18% was predicted from the data analysis as the optimal biodiesel yield. This study developed an optimal temperature of reaction, time of reaction, and the ratio of alcohol-to-oil parametric conditions for producing biodiesel from parsley seed oil and also identified the fatty acid methyl esters (FAME) present in the biodiesel. The biodiesel's fuel properties were within the requirements of D6751 of the American Society for Testing and Materials (ASTM)
