Catalytic Ozonation of Dye Solutions in a Semi-Batch Reactor
Pirgalıoğlu, Saltuk; Özbelge, Ayşe Tülay; Department of Chemical Engineering (2008)
Treatment of textile wastewaters containing dye materials using the conventional methods based on biological treatment is not possible. In order to overcome this problem, ozonation based on the oxidation of organic pollutants with ozone gas dissolved in aqueous phase have been studied widely. Catalytic ozonation and advanced oxidation processes (AOP) are also used in order to increase the efficiency of sole ozonation In this work, catalytic ozonation processes in the presence of Copper Sulfide (CuS) powder ...
Catalytic ozonation of synthetic wastewaters containing three different dyes in a fluidized bed reactor
Balcı, Ayşe İrem; Özbelge, Ayşe Tülay; Department of Chemical Engineering (2011)
Environmental regulations have imposed limitations on a wide variety of organic and inorganic pollutants in industrial textile wastewaters. There are several degradation methods used in literature studies. Among these methods ozonation is one of the most considered way to degrade refractory chemicals in textile wastewaters. In recent years, catalytic ozonation as being one of the advanced oxidation processes (AOPs), is applied to reduce the ozone consumption and to increase the Chemical Oxygen Demand (COD) ...
Catalytic pyrolysis of plastic wastes over SAPO-34 catalyst
Bursalı, Tülay; Sezgi, Naime Aslı; Doğu, Timur; Department of Chemical Engineering (2014)
Thermoplastic materials have a wide variety of usage area due to their low costs and easy processing properties. However, these materials cause a serious environmental pollution because of being non-biodegradable and their long-term self-recycling. Considering energy need and clean environment, it is proper to degrade thermoplastic materials into lower moleculer weight products which are potential raw materials for petrochemical industry. In addition, it is possible to decrease the reaction temperature & ti...
Catalytic ozonation of an industrial textile wastewater in a heterogeneous continuous reactor
Polat, Didem; Balci, Irem; Ozbelge, Tulay A. (2015-09-01)
Textile wastewaters (WWs) are highly colored and non-biodegradable having variable compositions of colored dyes, surfactants and toxic chemicals. Discharge of these WWs to the environment is very detrimental for ecosystems, therefore new methods have been investigated in order to meet the quality criteria of water and the discharge standards of the partly treated WWs. Recently, catalytic ozonation being one of the advanced oxidation processes (AOPs), is considered as an effective method that can be used in ...
Catalytic degradation of polypropylene over alumina loaded mesoporous catalysts
Obali, Zeynep; Sezgi, Naime Aslı; Doğu, Timur (2012-10-01)
The catalytic thermal degradation of polypropylene over aluminum containing ordered mesoporous MCM-41 and SBA-15 based materials was studied in a semi-batch reactor. Heavier molecules degraded to lighter hydrocarbons in the presence of catalysts and they gave high ethylene selectivity among the gaseous products. Additionally, butane selectivity increased with the use of catalysts. SBA-type catalysts showed higher selectivity to lighter hydrocarbons (<C-14). C-7 selectivity among the liquid products was high...
