Abstract— In this present investigation biodiesel was developed from waste chicken fat having high free fatty acids (FFA).Two two step esterification method was used to develop the biodiesel from waste chicken fat. This two-step esterification method consists of pretreatment (Acid esterification) followed by Alkaline esterification. The properties of the biodiesel were measured and compared with petroleum diesel. Performance and emission test was conducted in compression ignition engine with chicken fat biodiesel and its blends, compared with petroleum diesel. For lower biodiesel blends brake thermal efficiency is increasing and specific fuel consumption is decreasing as compared to petroleum diesel. The exhaust gas emissions also reducing for lower biodiesel blends compared to petroleum diesel. The experimental results proved that use of chicken fat biodiesel in compression ignition engine is a viable alternative to petroleum diesel.
Keywords—Fatty acids, Biodiesel, chicken fat, esterification.
I. INTRODUCTION
In 1895, Rudolf Diesel developed a new engine with the intention that it could use a variety of fuels, including vegetable oil (peanut oil), when he showcased it to the public at the 1900 in Paris. But the diesel engine became more widely adopted in subsequent years, because petroleum-based diesel fuel proved to be less expensive and became the fuel of choice.
However in 21st century investigations on renewable energy resources are continuing extensively due to increasing dependence on petroleum products. Besides, the combustion of petroleum based fuels over the past century has dramatically increased the emission of carbon dioxide and other greenhouse gases in the atmosphere. Concerning environmental damage the transport sector has a clear responsibility. So many researchers have been conducted in worldwide to these problems found that Biodiesel is one of the most renewable energy sources for diesel engines. Biodiesels not only decreasing dependency on petroleum products , also reducing greenhouse gas emissions because these are manufactured from plants, which obtain carbon dioxide from the air during photosynthesis, its use reduces overall CO2 emissions[1].
