Due to its toxic and corrosive nature, H2S should be safely removed from the gases produced in gasification or combustion processes. In this study, adsorption of hydrogen sulfide was investigated on a natural zeolite, namely clinoptilolite. H2S adsorption characteristics of Western Anatolian clinoptilolite was studied in a fixed-bed system at different temperatures between 100 and 600 degreesC at atmospheric pressure. H2S adsorption capacity of clinoptilolite was found to be about 0.03 g S/g clinoptilolite at 600 degreesC. A deactivation model considering concentration dependence of activity term was applied to experimental results and adsorption rate constant and activation energy values were evaluated. Good agreement of the experimental breakthrough curves with the model predictions was observed.

Removal of boron from aqueous solutions by continuous polymer-enhanced ultrafiltration with polyvinyl alcohol Dilek, C; Ozbelge, HO; Bicak, N; Yılmaz, Levent (2002-01-01) Boron is a highly contaminating metal due to its toxic effects for plants even at very low concentrations. Continuous polymer-enhanced ultrafiltration (PEUF) was applied for removal of boron from aqueous solutions. The effects of operating parameters on the performance of PEUF were investigated. A commercial polymer, polyvinyl alcohol (PVA) was used as the boron-complexing agent. The methodology consists of two steps: complexing boron with PVA following separation of boron and polymer complexes by ultrafilt...
Analysis of material collected on particles exposed to volatile matter of bituminous coal in a fluidized bed Vural, H (1997-05-01) The activity of fluidized bed particles towards the volatile matter of a bituminous coal was analysed by measurement of tar yield and the direct measurement of CO2 concentration in the exhaust gas from the devolatilization of bituminous coal particles in a laboratory-scale fluidized bed reactor. In a third approach, thermogravimetric analysis (t.g.a.) of the fluidizing particles was performed, indicating that calcium-containing particles exhibited the largest weight loss. In a fourth approach, a mass spectr...
Synthesis of Tungstophosphoric Acid Incorporated Mesoporous Alumina Catalysts for Methanol Dehydration in DME Synthesis Şener, M İlker; Sezgi, Naime Aslı; Doğu, Timur; Doğu, Güşen; Oktar, Nuray (null; 2016-04-27) Dimethyl ether (DME) is considered as a highly promising environmentally clean diesel fuel alternate, which can be produced from synthesis gas. It has high cetane number (55-60) and clean burning properties [1]. Possibility of using CO2 as the carbon source in DME production makes this process even more attractive as a carbon neutral technology. Production of DME from synthesis gas requires a bifunctional catalyst combination, for methanol synthesis and dehydration functions. As for the methanol synthesis ...
Investigation of Turkey's carbon dioxide problem by numerical modeling Can, Ali; Tokdemir, Turgut; Department of Engineering Sciences (2006) CO2 emission is very important, because it is responsible for about 60% of the "Greenhouse Effect". The major objectives of this study were to prepare a CO2 emission inventory of Turkey based on districts and provinces by using the fuel consumption data with respect to its sources, to find the CO2 uptake rate of forests in Turkey based on provinces and districts, and to estimate the ground level concentration of CO2 across Turkey using U.S. EPA's ISCLT3 model for the preparation of ground level concentratio...
Removal of imidacloprid from wastewaters by ozonation and photo-ozonation Sönmez, Büşra; Dilek, Filiz Bengü; Department of Environmental Engineering (2019) The widespread occurrence of micropollutants in the receiving water bodies apparently shows that conventional wastewater treatment plants (WWTP) are not capable to remove these compounds. Imidacloprid (IMI), which is a specific pollutant and an insecticide, exceeded Environmental Quality Standards (EQS) value (0.14 µg/L, annual average) in several receiving water bodies of WWTPs in Yeşilırmak basin. With the aim of examining advanced treatment methods to meet EQS value and to achieve good surface water qual...
