“…In some European countries, for example rapeseed oil, Brazil is already in use, depending on the region, can be produced from soy, castor oil or babassu [6] oil. Another highlight is the use of oils used in frying whose nobler purpose was hitherto the production of soap or disposed of in a sanitary [33] landfill. The high price of vegetable oils has become non-competitive biodiesel economically forward to petroleum diesel, programs and government incentives are needed.…”

“…This residue is regularly poured down the drain, resulting in problems for waste water treatment plants and energy loss, or is integrated into the food chain through animal feeding, thus becoming a potential cause of human health problems 16,17 . The objective of this work was to optimize the process for biodiesel production from WFO using potassium hydroxide supported on coconut shell activated carbon (KOH/AC).…”

Heterogeneous catalysis of transesterification using potassium hydroxide supported on coconut shell activated carbon (KOH/AC) catalyst was used to produce biodiesel from waste frying oil (WFO) and methanol. The effects of reaction temperature, methanol to oil molar ratio, catalyst bed height, reaction time, and reusability of catalyst on the conversion to fatty acid methyl ester in a packed bed reactor were studied. The results showed that increasing reaction temperature, methanol/oil molar ratio, catalyst bed height, and reaction time can enhance the conversion of WFO. The optimum conditions were a reaction temperature of 60°C, methanol/oil molar ratio 25:1, catalyst bed height 250 mm, and reaction time 2 h which yielded 86.3% of the conversion. KOH/AC could be used repeatedly for 4 times without activity loss and no activation treatment was required. The fuel properties of biodiesel were determined.

“…19 Moreover, the land use of growing oil seeds as feed stocks for the biodiesel production competes with the use of land for food production. 20,21 From an economic point of view, the production of biodiesel is feed stock sensitive. 22 The high cost of vegetable oil which could be upto 75% of the total manufacturing cost can make the production cost of biodiesel approximately 1.5 times higher than that of diesel.…”

Biodiesel is an alternative fuel to diesel engine that can replace or reduce the use of petroleum diesel. Biodiesel is derived from vegetable oils, animal fats, and waste cooking oils through transesterification reaction. This paper reviews the optimization of transesterification process for different varieties of biodiesel by considering the factors such as alcohols, fatty acid content, molar ratio of alcohols to oil, catalyst concentration, reaction temperature, and reaction time. The review also addresses various technical aspects of biodiesel usage in diesel engine to improve the cold flow properties, performance, combustion characteristics and reduce the emission characteristics, particularly nitric oxide and smoke compared to diesel through either modifying engine parameters like fuel injection pressure and timing or fuel modification by blending with alcohols, diesel, and metal based additives.
