3. Introduction to Bio-Diesel from Non-Edible Seed Oils
The National Institute of Technology Durgapur presents a
B.Tech Final Year Project on Bio-Diesel from Non-Edible
Seed Oils, exploring the production, performance, and
environmental impact of bio-diesel. The project is
supervised by Prof. Apurba Layek.

4. What is Bio-Diesel?
Understanding Bio-Diesel and Its Benefits
Bio-diesel is a renewable liquid fuel derived from
non-edible seed oils and fats, offering reduced emissions
and biodegradability compared to petroleum-based diesel.
1 Definition of Bio-Diesel
Bio-diesel addresses the increasing greenhouse gas
emissions from transportation and offers a promising
alternative to traditional fuels.
2 Need for Bio-Diesel
Vegetable oils, yellow grease, used cooking oils, and
animal fats are the primary sources of bio-diesel, with a
focus on non-edible seeds for sustainability.
3 Sources of Bio-Diesel
The project evaluates the environmental and economic
impacts of using edible plant oils for bio-diesel production,
considering factors such as availability, cost, and reactivity.

5. Cotton Seeds for Bio-Diesel Production
Extraction and Uses of Cotton Seed Oil
Oil Percentage in Seed
Cotton seeds contain
approximately 15 to 20 percent oil,
which is extracted and refined to
remove gossypol, a naturally
occurring toxin.
Process of Oil Extraction
The extraction process involves
cleaning, husking, softening,
flaking, oil extraction, and refining
to obtain cotton seed oil for various
applications.
Performance Analysis
Performance parameters of cotton
seed oil biodiesel are evaluated,
including fuel consumption, power
generation, and emissions to
determine its efficiency.

6. Karanja Seeds for Bio-Diesel Production
Karanja seeds, also known as Pongamia Pinnata, offer a
viable source of non-edible oil for bio-diesel production.
The seeds have a high oil yield of 27-39% and can thrive in
diverse environmental conditions, making them a
sustainable option for bio-diesel production.

7. Transesterification Process for Biodiesel
Converting Non-Edible Oils into Bio-Diesel
The process of transesterification is used to convert non-edible
oils into bio-diesel, involving the displacement of alcohol from
an ester to reduce viscosity and improve combustion properties.

2 Extraction of Oil
The extraction of oil from non-edible seeds is carried out using
a Soxhlet extractor, which concentrates the desired compounds
for bio-diesel production.

8. Performance Parameters of Cotton Seed Oil Biodiesel

engine efficiency, emissions, and power
generation.
Optimization of Biodiesel Blends
The project identifies the most optimized
blend of Karanja seed oil biodiesel with
diesel fuel, considering factors such as
power generation, fuel consumption, and
emissions.

The analysis of Cotton seed oil and Karanja
seed oil biodiesel-infused fuels shows both
improve diesel performance, reducing
emissions and enhancing production economics
When biodiesel is used, there's a marked decrease in NOx
and hydrocarbon emissions compared to regular diesel
due to its lower sulfur content, offering a more
environmentally friendly fuel option.
Industrial use of Karanja seed for biodiesel wouldn't
disrupt other industries, unlike cotton seeds, which
have multiple uses.
