Koya University Researcher Publishes New Article

Mr. Rebwar Kirmanj Abdul-Rahman, Koya University instructor at Chemical Engineering DepartmentFaculty of Engineering has published a research paper. His research is entitled “Sustainable Biodiesel Production from Waste Cooking Oil and Chicken Fat as an Alternative Fuel for Diesel Engine. “  With regard to choosing this research, Mr. Rebwar says “Because it is a crucial subject nowadays throughout the world of how to produce energy and fuel from animal fat waste and oil. Furthermore, the production of Biodiesel Fuel which has many significant characteristics including the reduction of environment-contaminating gases.” Regarding this subject, the conclusion of Mr. Rebwar’s research was the production of Diesel Fuel from animal fat waste and oil. 


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 are 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 

Intriguing point of the research: 

“One of the interesting points of my research is how to produce Diesel Fuel from animal fat waste and oil; at the same time, this research has a vital role in the field of energy to build the scientific infrastructure of this knowledge.” Mr. Rebwar added. 

All the energy engineering, environmental engineering, petroleum and chemical engineering are considered to be the readers’ circle and beneficiaries of this research.

Department of Chemical Engineering (DCHE)

Chemical Engineering Department at Koya University was established in 2006. The department is unique in the Iraqi Kurdistan Region because this field of engineering does not exist at other universities and higher education institutions within the region. The department is currently awarding a Bachelor of Science in Chemical Engineering that normally takes four years of study. The department of chemical engineering at Koya University aims at producing highly trained and professional chemical engineers that the Kurdistan region very much needs for its development. On research related activities, the department strives to create an environment for its academic staff to conduct internationally competitive researches in their fields of expertise and provide consultancy services to a variety of industrial sectors including oil, gas and energy industries. 

Overall, the department aims at producing world class graduates and conducting high quality research.
