Ever increasing demand and consequent rise in prices of petroleum products, stringent emission standards, the exponential depletion rate of fossil fuel reserves and escalation in the number of vehicles on the road have forced us to look for alternatives to meet the present and future demands of the energy requirements. Biodiesel production from waste oils and fats are cost effective methods which prevent the environmental pollution by proper disposal techniques. In this study, biodiesel was prepared from the waste effect chicken fat using the two stage esterification process. The present investigation deals with the cold exhaust gas recirculation (EGR) with the flow rates of 10, 20, 30% on a four stroke, single cylinder, direct injection (DI) diesel engine fueled with waste chicken fat biodiesel blends to reduce the NOxemissions of the engine. Experimental results showed higher oxides of nitrogen emissions when fueled with waste chicken fat biodiesel without EGR and found reduced NOxemissions about 25% when operating with B20 fuel blend with 30% EGR. The EGR level was optimized as 20% based on the significant reduction in NOx emissions, minimum possible smoke, CO, HC emissions and comparable brake thermal efficiency.

In recent decade, the demand for fuel as a source of energy has been dramatic. In fact, many oil and gas reservoirs are declining around the world. The use of fossil fuels such as oil, coal, and natural gas is contributing to the phenomenon of global warming. This is because it emits high quantities of carbon dioxide and other greenhouse gases to the atmosphere. Thus, many researchers and energy companies are investigating the production of an environmental friendly fuel that reduces the emission of greenhouse gases. Thus, bio fuel is one of the most obvious alternative sustainable fuels that can be produced from used vegetable oil and animal fats as well. Indeed, it has several advantages. For example, a biodegradable and a renewable energy reduces global warming phenomenon. Thus, this work is an attempt to produce a biodiesel fuel from chicken fat and waste cooking oil. Also, it was found that it is possible to produce biodiesel from chicken fat and waste cooking oils using transesterification reaction method. Furthermore, the process optimization was also adopted; for example, methanol to oil ratio. It has been found that the yield percentages of the produced biodiesel is increased by increasing the amount of methanol. In addition, the maximum conversion to ester could be achieved at methanol: oil ratio about 7:1. at 60 °C.

Heterogeneous catalyst has been viewed as a promising catalyst for biodiesel production. This study employed Turritella terebra (TT) shell as a source for synthesizing heterogeneous CaO catalyst for biodiesel production via transesterification by utilizing chicken fat as a feedstock. The TT shell CaO catalyst was characterized and its catalytic performance was studied. The spectrographic methods that include FTIR, SEM, PSA, and BET-BJH were employed for characterization of the synthesized CaO. The TT shell CaO catalyst optimally produced chicken fat biodiesel (CFB) with reaction parameters at catalyst concentration of 4 wt%, chicken fat to methanol molar ratio of 1:12, reaction temperature of 60°C, and reaction time of 90 min. The optimal yield was 94.03% and the TT shell CaO catalyst still yield 79.19% of CFB on the fifth cycle of reaction. This study has implied that TT shell is a feasible and attractive renewable source of heterogeneous CaO catalyst for biodiesel production.
