Investigation of combustion of lignite and torrefied biomass in a thermogravimetric analyzer (TGA) and in a circulating fluidized bed (CFB) under oxy-fuel combustion conditions
Barzegar, Ramin; Yozgatlıgil, Ahmet; Department of Mechanical Engineering (2019)
In this study, the combustion of Turkish lignites (Orhaneli and Soma), torrefied woodchip, and their blends was studied under oxygen-enriched and oxy-fuel combustion conditions in a thermogravimetric analyzer. The iso-conversional kinetic methods were used to estimate the Arrhenius parameters and the uncertainty assessments associated with the kinetic calculations were considered. The co-combustion experiments showed a synergetic effect between the biomass samples and Orhaneli lignite. Based on the obtained...
Investigation of SO2 removal characteristics with limestone under oxycombustion conditions
Avşaroğlu, Sevil; Sanin, F. Dilek.; Department of Environmental Engineering (2019)
One of the technologies to increase combustion efficiency and decrease CO2 and other emissions is Oxy-Fuel Combustion. Combustion efficiency is higher and emissions are lower when the oxygen concentration of air is higher. In this thesis different characteristics of two indigenous Turkish lignites are investigated by Thermal Gravimetric Analysis (TGA). Pyrolysis is carried out under both N2 and CO2 atmospheres and combustion characteristics is also examined. CO2 acts as an inert gas at lower temperatures. T...
Investigation of alkaline pretreatment parameters on amulti-product basis for the co-production of glucose and hemicellulose based films from corn cobs
Toraman, Hilal Ezgi; Bakır Bölükbaşı, Ufuk; Özkan, Necati; Department of Chemical Engineering (2012)
There is an increasing trend in the world for using renewable sources of fuels and chemicals due to the continuous depletion of fossil fuel reserves besides the environmental issues related with the exploitation of these resources. Lignocellulosic biomass is seen as the most promising candidate to be used instead of fossil sources because of its availability, relatively low price and less competition with food and feed crops. In this study, corn cobs, a lignocellulosic agricultural waste, were subjected to ...
Investigation of methane production potential of industrial sludges mixed with domestic sludge during anaerobic digestion
Aksu Bahçeci, Hazal; Sanin, F. Dilek.; Department of Environmental Engineering (2019)
Anaerobic digestion has been established as a sludge stabilization and biogas production method for domestic sludge. However, anaerobic digestion has limited success in industrial sludge applications. In this thesis sludge from two different Organized Industrial Districts (OIDs) and textile industry are mixed with urban wastewater sludge with and without ultrasound pretreatment to investigate their energy production potential by using BMP tests. Sludges were digested alone (A for industrial, D for domestic ...
Investigation of biogas production potential of three different sludges after thermal hydrolysis
Arı Akdemir, Ece.; Sanin, F. Dilek.; Department of Environmental Engineering (2019)
Biogas production through anaerobic digestion using biological sludge is one the sustainable approaches. Hydrolysis is the first and rate limiting step during anaerobic digestion. For enhancement of hydrolysis of sludge, it is feasible to investigate pre-treatment before anaerobic digestion process. In this research, biogas and methane production potentials of municipal wastewater treatment plants sludge, membrane bioreactor sludge and organized industrial district sludge were investigated using small scale...
