In this present study transesterification of used vegetable oil (UVO) using synthesized activated anthill as catalyst was investigated. The catalyst was prepared via calcination process, characterized by Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD) and Fourier transform infrared (FTIR) techniques. From the BET analysis; calcination temperature has a positive impact on the textural properties. The XRD shows that the catalyst is crystalline in nature. Fatty acid methyl esters (FAME) was produced using thermally activated anthill as catalyst. The optimal FAME yield of 94.85 % was obtained at Methanol/Oil (M/O) 9:1, catalyst loading 1.5 wt%, reaction temperature of 65 ᵒ𝑪 and reaction time of 2 h. The physico-chemical properties of UVO – FAME produced was found to be within the American Society for Testing and Methods (ASTM). Hence, the study reveals that used vegetable oil catalyzed by novel activated anthill could be an effective feedstock to produce sustainable energy. Keywords: Anthills, FAME, Central composite design, Heterogeneous, used vegetable oil.

“…However, it has to be concluded that various factors affects the NO and NOx formation which may result in contradictory readings. The ambient conditions, gas residence time of the fuels, fuel spray characteristics, EGR application, oxygen content, physical condition of the experimental equipment, and fluctuations can all affect the NO and NOx formation of any fuel, hence it is difficult to figure out the most dominant parameter causing the difference [43,[64][65][66].…”

Although waste animal fats such as chicken fat are promising alternative energy sources, biodiesels produced from these type of feedstocks hardly satisfies the EN14214 biodiesel standards. In this study, biomixtures were prepared by blending cottonseed biodiesel and chicken rendering fat biodiesel which were produced via transesterification method. Biodiesels were blended with each other at 60/40, 50/50 and 30/70 volume ratios to produce CO60CH40, CO50CH50 and CO30CH70 fuels. First, fuel properties of the neat biodiesels and novel biomixtures were measured and compared to European biodiesel standards and diesel. Then, the engine performance, combustion characteristics and exhaust emissions of these novel biomixture fuels were measured in a three-cylinder indirect injection diesel engine under various engine loads and at constant speed of 1500 rpm. The fuel characterisation showed that CO60CH40 and CO50CH50 biomixtures met the European standards. The Brake Specific Energy Consumption (BSEC) and Brake Thermal Efficiency (BTE) of all biomixtures were comparable with CO100, CH100 and diesel at the full engine load. The combustion results revealed that the maximum in-cylinder pressure and energy release values of the CO50CH50 were 4.2% and 4.4% higher than the diesel at full engine load because of optimised fuel properties of biomixture such as molecular structure, viscosity, cetane number and iodine value. CO50CH50 had 2.9% reduced CO2 and comparable CO emission compared to diesel, which were also 5.6% and 13% lower than cottonseed biodiesel respectively. However, NO emission of CO50CH50 was found 3.8% and 5.8% higher than diesel and cottonseed biodiesel. A 6.5% reduction on NO emission was observed when CO60CH40 biomixture fuel was used instead of diesel. To conclude, this research showed that blending of cottonseed and chicken fat biodiesels is a promising approach to meet the EN14214 standards, improve in-cylinder pressure, optimise energy release and reduce exhaust emissions. Blending of different biodiesels will be tested as a future work.

“…It has similar emission characteristics to other types of biodiesel. The WCO biodiesel burns with lower temperatures, thus resulting in lower NOX emission [9][10][11][12]. However, in some other studies, NOX increases and soot emissions decrease compared to the known high NOX profile of biodiesel [13][14][15][16][17].…”

It is necessary to meet increasingly stringent emission standards of IC engines, reducing the emission values. While improving engine parameters and combustion chamber geometries can reduce emissions, also the research continues for alternative fuels. Biodiesel production from waste cooking oils has advantages in terms of recycling, environment, and cost. Waste cooking oils can be used as fuel in compression ignition (CI) engines with minor modifications. Biodiesel can be used in neat form or blend with diesel. In this way, there is no need to make any modifications to the existing diesel engines. In this study, diesel was blended with biodiesel at 20% (B20) and it was used as fuel in a CI engine. The performance and emission values of this blend were compared according to neat diesel fuel. As a result of the experimental and CFD simulation studies, it was observed that the use of the B20 fuel blend reduced CO emissions by 22.7% and soot emissions by 15.6%. In addition, the maximum pressure inside the cylinder has decreased by 2.7%.
