“…In the present study, transesterification process was explored to synthesize biodiesel from karanja oil under different operating conditions such as methanol:oil molar ratio, catalyst concentration (wt %), reaction time (min), reaction temperature (°C) and stirrer speed (rpm) using β-tricalcium phosphate as a catalyst. These are the most important biodiesel parameters which significantly affected the biodiesel yield [28]. In each experimental setup, the effect of biodiesel parameters on biodiesel yield was studied when one of the biodiesel parameter was varied while other biodiesel parameters were kept constant.…”

In recent times, the rate of energy consumption goes on increasing and the world is desperately searching for new sources of fuel. Biodiesel (fatty acid methyl esters) is an alternative renewable energy resource for the next generation. Biodiesel has several advantages which include its non-toxic nature, it is biodegradable and it reduces greenhouse gas emissions. β-Tricalcium phosphate (β-Ca3(PO4)2) catalyst was synthesized from fish waste. Fish waste contains calcium phosphate which is converted into β-tricalcium phosphate since it has low crystallinity and hydroxyl (OH) groups which decrease the potential to be a good catalyst for the synthesis of biodiesel through transesterification. This paper explores the synthesis of biodiesel using β-tricalcium phosphate (β-Ca3(PO4)2) as a heterogeneous catalyst. Pongamia pinnata (Karanja) oil was extracted from seeds through the solvent extraction process. Intended for the development of easier transesterification process, stable and active heterogeneous β-tricalcium phosphate (β-Ca3(PO4)2) catalyst was synthesized and used for the P. pinnata (Karanja) oil transesterification process. The synthesized heterogeneous catalyst was characterized by XRD, FT-IR, SEM and EDX to determine its structural and morphological characteristics. The catalyst exhibited good catalytic activity on reuse. Biodiesel yield was greatly dependent on operating parameters such as catalyst concentration, methanol to oil molar ratio, reaction temperature and reaction time. Effect of co-solvent on biodiesel was studied by using different co-solvents in transestrification reactions. High quality and maximum biodiesel yield (97 %) was obtained under the optimized reaction conditions (methanol to oil molar ratio, 10:1 (tetrahydrofuran (THF):methanol 1:1); reaction time 90 min; catalyst concentration 2.5 wt % and stirrer speed 650 rpm at 65°C). Reusability of catalyst was examined up to five runs and found the catalyst was reusable up to five times without much loss of catalytic activity.

The depletion of fossil fuel reserves and increasing demands for diesel are considered to be important triggers for many of the initiatives that have been taken to search for possible sources for the production of biodiesel from materials available within the country. It is possible to produce biodiesel from waste/used cooking oils (WCO) that is comparable in quality to that of fresh vegetable oil. Not only does reuse of WCO, which can otherwise harm human health, reduce the burden on the government of treating oily wastewater, disposing of the waste, and maintaining public sewers, it also significantly lowers the production cost of biodiesel. In the process of frying, oil undergoes many reactions, leading to the formation of a number of undesirable compounds, such as polymers, free fatty acids, and many other chemicals. This poses challenges in the transesterification of WCO. This article covers different techniques in the production of biodiesel from WCO.It also compares combustion, emissions, and engine performance characteristics of biodiesel from WCO as well as factors affecting biodiesel production from WCO and its economic feasibility.
