CO2 reduction in reverse flow reactors Aksu, Nevzat Can; Üner, Deniz; Atamer, İbrahim Bülent; Department of Chemical Engineering (2013) Syngas, a mixture of CO and H2, is a very important industrial gas mixture, because it can be used for synthesizing products such as synthetic natural gas, ammonia and methanol. The main purpose of this work was to obtain CO by CO2 reduction. Reducible metal oxides are used as catalysts due to the fact that they can be reduced and re-oxidized upon changes in temperature, pressure and gas atmosphere. CeO2 was chosen for this cyclic reaction pathway based on the reports on similar studies in literature. It is...
CO2 mitigation from the flue gas of the iron steel making industry by microalgal cultures Çaylı, Direniş; Bayramoğlu, Tuba Hande; Demirer, Göksel Niyazi; Uludağ Demirer, Sibel (null; 2015-06-15) Integration of CO2 mitigation with nutrient removal from different wastewater sources can be realized by microalgae growth. In spite of being an option with significant environmental benefits, this technology still suffers from achieving high performances since atmospheric concentration of CO2 limits microalgae growth; i.e. biomass accumulation. This is why the use of flue gas with CO2 concentrations of 20-25% (by volume) should be considered as an inorganic C source for the microalgae culture reactors. Thi...
CO2 injection in carbonates Izgec, O.; Demiral, B.; Bertin, H.; Akın, Serhat (2005-07-28) Started as an EOR technique to produce oil, injection of carbon dioxide which is essentially a greenhouse gas is becoming more and more important. Although there are a number of mathematical modeling studies, experimental studies are limited and most studies focus on injection into sandstone reservoirs as opposed to carbonate ones. This study presents the results of computerized tomography (CT) monitored laboratory experiments to characterize relevant chemical reactions associated with injection and storage...
CO2 Decline in Alaşehir (Turkey) Geothermal Reservoir Akın, Serhat; Aydın, Hakkı; AKIN, TAYLAN (2021-10-01) Reinjection of gas free of brine into the peripheries of a geothermal reservoir may gradually decline non-condensable gas (NCG) concentration in the reservoir fluid during the operation of geothermal power plants. As a result, gradually decreasing gas emissions can be observed. In this study, we use separator data to calculate produced CO2 amount in the reservoir fluid. The data used is from the Alaşehir geothermal area that is certainly not the one and only target for geothermal production in Turkey. Data ...
CO2 hydrogenation to methanol over supported copper and gallium based catalysts at the atmospheric pressure Osmanağa, Sezer; İpek Torun, Bahar; Önal, Işık; Department of Chemical Engineering (2022-8) The continuous increase of the CO2 concentration in the atmosphere has been negatively impacting the environment, due to its contribution in the global warming. Hence, it is necessary for the current CO2 valorization techniques to advance in order to make use of CO2. A possible technique is the CO2 hydrogenation to methanol and DME. The process of CO2 hydrogenation to methanol has been taking place in industry for about a century. However, due to the thermodynamic limitation imposed by the reaction stoichio...
