The Potentials of Reaction Parameters on Rhynchophorus Phoenicis Nano-Catalysts Based Biodiesel Production from Waste Material Feedstocks

Heterogeneous catalysts are known to improve the trans-esterification Process in biodiesel production by eliminating the extra processing costs involved in homogeneous catalysis, as well as reducing the generation of pollutants. Heterogeneous catalysts promote easy recovery, reusability and a cost-effective green process. These catalysts tolerate high FFA and moisture content. In this research the trans-esterification process was used to produce biodiesel from Carica papaya (pawpaw) and Citrullus lanatus (water melon) seed oil. To improve biodiesel performance, an alumina-chitosan nanocomposite a heterogeneous catalyst synthesized from hard shell of Rhynchophorus phoenicis using standard methods was compare to biodiesel production using a homogeneous catalyst potassium hydroxide (KOH). Reaction parameters (reaction temperature and reaction time) were used for optimization of biodiesel production. The average values obtained for effect of time ranged from 42.30±0.20-63.10±1.30%, 49.30±1.50-64.70±1.00%, 71.40±0.70-79.80±0.20%, 80.46±0.20-97.10±0.30%, 81.20±1.20-86.10±1.60% and 79.39±0.40-83.90±0.50% for 30 minutes, 60 minutes, 90 minutes, 120 minutes, 150 minutes and 180 minutes respectively. Variation of temperature for the production of biodiesel from Carica papaya and Citrullus lanatus seed oil with KOH and Nanocomposite catalyst range from 63.09±0.60-95.20±1.55, 49.10±0.45-79.30±0.75, 66.00±1.00-97.10±0.45 and 59.20±0.95-83.40±0.85% for 40, 45, 50, 60, 80 and 90°C respectively. The optimum conditions for the trans=esterification process were 80°C reaction temperature, and 120 minutes reaction time.
