Biodiesel: An alternative fuel in EU and Turkey

Akbas, C. Y.
Ozgur, E.
The energy issue is an extensively discussed subject. There are many concerns about the future of energy supply for human beings. Conventional sources are declining and the newcomers are starting to take place. Biodiesel is one of these alternatives and may be the most important one among the renewable energy sources for its convenience in usage as a fuel in the transportation sector. Although biodiesel was developed some two to three decades ago, it is not commonly used, mainly due to high production costs. Recently, increasing concerns on environmental protection have accelerated the popularity of biodiesel. In addition, interests in biodiesel have also been emerged with recent fluctuations in crude oil prices and uncertainities about the future energy security. The aim of this article is to make a review on the history, production techniques, and applications of biodiesel. The regulations concerning the biodiesel sector in European Union (EU) and Turkey with regional production histories are mentioned. The recommendations for developing the Turkish biodiesel sector are also given.


Limitations of three-phase Buckley-Leverett theory
Akın, Serhat (Informa UK Limited, 2005-07-01)
The broad objective of this study is to determine the limitations of the three-phase relative permeability estimation technique by using the experimental approach. In order to achieve this goal, three-phase relative permeability experiments were conducted on a Berea sandstone core plug by using brine, hexane and nitrogen gas. An unsteady-state analytical technique and a numerical technique where a black oil simulator was coupled with a global optimization algorithm in a least squares manner was used to comp...
Electrochemical performance and modeling of lithium-sulfur batteries with varying carbon to sulfur ratios
Michaelis, Charles; Erisen, Nisa; PALA, DAMLA EROĞLU; Koenig, Gary M. (Wiley, 2019-02-01)
Lithium-sulfur batteries have attracted much research interest because of their high theoretical energy density and low-cost raw materials. While the electrodes are composed of readily available materials, the processes that occur within the cell are complex, and the electrochemical performance of these batteries is very sensitive to a number of cell processing parameters. Herein, a simple electrochemical model will be used to predict, with quantitative agreement, the electrochemical properties of lithium-s...
Field-Scale Analysis of Heavy-Oil Recovery by Electrical Heating
Hascakir, B.; Babadagli, T.; Akın, Serhat (Society of Petroleum Engineers (SPE), 2010-02-01)
Electrical heating for heavy-oil recovery is not a new idea, but the commercialization and wider application of this technique require detailed analyses to determine optimal application conditions. In this study, applicability of electrical heating for heavy-oil recovery from two heavy-oil fields in Turkey (Bali Raman and Camurlu) was tested numerically. The physical and chemical properties of the oil samples for the two fields were compiled, and in-situ viscosity reduction during the heating process was me...
Geothermal Energy: Current Status in Turkey with EU Perspective
Vardar Acar, Ceren (Informa UK Limited, 2009-01-01)
The world's growing energy demands carry the energy into an important stage. Crude oil will be able to supply increasing demand until peak world production is reached. Forecasts show that this peak time is about 2020. Turkey and the world will deplete economically recoverable fossil resources by the end of the 21st century. The energy gap caused by declining fossil resources has to be filled by expanding production of other sources. Geothermal energy is one of the most important options for filling this gap...
TASDEMIROGLU, E (Informa UK Limited, 1993-07-01)
This article begins with a brief review of the socioeconomic situation, energy resources, and energy consumptions in Turkey. The estimates for the sustainability years of fossil fuels and the potential of renewable energies are given. Hydropower, biomass, geothermal, solar, wind, wave, sea currents, and salt gradient are, in order of priority, listed among the renewable energy resources of the country. The importance of energy conservation is discussed in conjunction with the research results produced for t...
