Oil shale is an important energy resource alternative. Despite its recognition as an unconventional oil source, oil shale is also considered as an important solid fossil fuel alternative to coal and lignites due to the solid form and remarkable extent of organic content. Utilization possibilites, similar to coal and lignites, have been considered in the past decades and direct use of oil shales in thermal power production has been possible in countries like Estonia and China. In the perspective of utilization of oil shales in a similar manner to coal and lignites, problems and restrictions related to the inorganic ash-making and potentially pollutant constituents are applied. In this respect, cleaning of this important energy source through mineral processing methods, particularly by flotation, is an outstanding option. However, on the basis of unique features and distinctive characteristics, treatment of oil shales like a type of coal is a big perception and may be highly misleading. This paper discusses specific challenges regarding flotation behavior of oil shales with reference to the surface characteristics and behavior of oil shale entities probably the most important aspect that determines the efficiency and success of the flotation based cleaning process.

Solvent extraction of scandium from lateritic nickel- cobalt ores using different organic reagents Ferizoglu, Ece; Kaya, Serap; Topkaya, Yavuz Ali (2016-09-28) Scandium is the most important and strategic metal that can be recovered as a by-product from lateritic nickel-cobalt ores. In this research, different extractants were investigated in order to extract scandium from a sulfate medium by a using a solvent extraction method. Generally, the organic extractants are classified as acidic, neutral and basic organophosphorus compounds. However, in solvent extraction of scandium, the acidic and neutral organophosphorus compounds are preferred due to their higher extr...
Evaluation of state owned indigenous coal fired power plants including coal reserves Güler, Mehmet; Güyagüler, Tevfik; Department of Mining Engineering (2010) Fossil fuels has preserved their importance in gradually increasing production and consumption of both energy and electricity of the world. Asia, especially China and India, has arisen new actors of the sector. Energy and electricity consumption of Turkey has also increased in parallel with her economic development, but due to her limited resources, she has become more and more energy dependent in order to meet her growing demand. Although hard coal is only found around Zonguldak region, with its abundant a...
Oil shales in the world and Turkey; Reserves, current situation and future prospects: A review Altun, Naci Emre; Wang, J. -Y.; Baggi, A. Suat; Kök, Mustafa Verşan (2006-01-01) Oil shales, which are kerogen-rich sediments, are one of the most important energy alternatives. The widely distributed deposits around the world and their vast amounts make them a promising option as a source of oil or as a solid fuel supplement. Nevertheless, the economics of retorting does not allow their utilization for oil production on a large scale with a few exceptions. Oil shale is an important potential energy resource for Turkey, being the second largest fossil energy source after lignite. This p...
Experimental investigation of an oil loss mechanism in internal combustion engines Sezer, Ahmet; Dursunkaya, Zafer; Department of Mechanical Engineering (2010) Oil loss mechanisms in internal combustion engines have been subject to many researches. By the help of technological developments effects of several problems due to oil losses were examined and tried to be reduced. Environmental pollution and performance loss are important issues that oil consumption in internal combustion engines contribute. In this study the effects of individual parameters on the oil accumulation in 2nd land crevice of internal combustion engines, volume between top compression rings, w...
Simultaneous optimization of electrical interconnection configuration and cable sizing in offshore wind farms Fahrioğlu, Murat; Sedighi, Mohsen; Moradzadeh, Mohammad; Kukrer, Osman (Springer Science and Business Media LLC, 2018-1-18) Offshore wind farm (OWF) is the largest renewable energy resource. The electrical interconnection cost of OWFs is a considerable fraction of the overall design cost of the farm. In order to minimize the investment and operational costs, this paper proposes an optimization formulation to find the optimal electrical interconnection configuration of wind turbines (WTs), and the optimal cable sizing simultaneously. This simultaneous minimization of total trenching length and cable dimensions creates a complex o...
