Jatropha curcas is a natural non-food resource with high oil-content seeds, that has attracted worldwide attention as it is an ideal renewable resource for the production of biofuels. With the increasing use of vegetable insulating oil in related industries, it is valuable to develop the vegetable insulating oils from Jatropha curcas seed oil. This...
Research on the use of Jatropha curcas triglycerides as biodiesel feedstock has received worldwide attention due to its inherent characteristics. Unlike palm oil, J. curcas oil is not edible, and thus, it will not disturb the food supply. However, to the researchers' experiences with the synthesis of J. curcas, oil-based biodiesel has shown that th...
The blistering decline in the Nigerian petroleum reserves coupled with the crucial sustainable development goal (SDG) No 7 (which is concerned with ensuring a universal access to cost-effective energy with low carbon footprint by 2030) have made it highly imperative for Nigeria (the 7th most populous country in the world) to intensify research and...
Jatropha curcas Linnaeus (Jatropha curcas L.) seeds have been found to be an ideal sustainable and low-cost source of catalyst and oil feedstock for biodiesel production. Jatropha cake, remained dregs after jatropha curcas oil (JCO) extraction, has been treated by two different techniques; calcination and potassium hydroxide (KOH) activation to be...

Waste cooking oil (WCO) is a promising feedstock for producing biodiesel, which plays a significant role in waste resource reusing and renewable energy production. It is known that cost is the main factor restricting the large-scale production of biodiesel. Therefore, the Life Cycle Cost (LCC) method was used to analyze the economic feasibility of the biodiesel production process from WCO. Our results show that the cost of producing 1 t of WCO biodiesel is 6291.56 RMB, which is 3.49% higher than the price of 0# diesel. The factors influencing WCO biodiesel production cost was further analyzed. Although WCO has a low commercial price, necessary pretreatment is inevitable and creates additional processing cost, since WCO cannot be directly used for transesterification to produce biodiesel. The cost of pretreatment process is relatively high, accounting for 15.60% of the total cost. Special waste management policy should be implemented and waste cooking oil recycling technology should be advanced, in order to make WCO biodiesel more economically competitive. Aspen Plus software was used to simulate the production process of biodiesel from WCO, and the production process was simulated by a two-step method. The practicability of simulation was confirmed by purity of biodiesel reaching 99.6 wt%. In the simulation, processing parameters of methanol rectification tower and biodiesel rectification tower were optimized to provide a reliable benchmark for the industrial biodiesel production from WCO.
