To verify the constancy of average cake porosity, constant applied-pressure filtration experiments were conducted under the guidance of a standard 23 factorial design. Two types of septa, two levels of slurry concentration and two levels of applied pressure were used. The null hypothesis that there is no influence exerted by the operating factors, i.e. septum, slurry concentration and applied pressure, on the average porosity was tested with an F-distribution and accepted as being true. This indicates that the average porosity remains constant throughout a constant applied-pressure filtration run within a specified statistical significance level.

An empirical method for the second viral coefficients of non-standard fluids Kis, Konrad; Orbey, Hasan (Elsevier BV, 1989-9) A new empirical method is proposed for the extension of Pitzer-Curl type correlations of the second virial coefficient to non-standard fluids as define
The effects of platinum particle size to the efficiency of a DYE sensitized solar cell (DSSC) Giray, Hasan Berk; Üner, Deniz; Department of Chemical Engineering (2010) The aim of this study was to modify the platinum particle size to observe the effects on the efficiency of a Dye Sensitized Solar Cell (DSCC). DSSC was prepared as follows: On the anode side, TiO2 was annealed on the transparent conducting oxide (TCO) which is SnO2:F coated and a cis-bis (isothiocyanato) bis (2,2'-bipyridyl-4,4'-dicarboxylato)–ruthenium(II) dye was adsorbed on the TiO2. On the cathode side, platinum was coated on TCO from an alcohol based solution of platinum (plasitol) by thermal decomposi...
Quantum chemical simulation of nitric oxide reduction by ammonia (scr reaction) on v2o5 / tio2 catalyst surface Soyer, Sezen; Önal, Işıl; Department of Chemical Engineering (2005) The reaction mechanism for the selective catalytic reduction (SCR) of nitric oxide by ammonia on (010) V2O5 surface represented by a V2O9H8 cluster was simulated by density functional theory (DFT) calculations. The computations indicated that SCR reaction consisted of three main parts. In the first part ammonia activation on Brønsted acidic V-OH site as NH4+ species by a nonactivated process takes place. The second part includes the interaction of NO with pre-adsorbed NH4 + species to eventually form nitros...
Mathematical modeling of fluidized bed combustors with radiation model Alagöz, Düriye Ece; Selçuk, Nevin; Department of Chemical Engineering (2006) Simultaneous solution of the conservation equations for energy and chemical species in conjunction with radiative transfer equation was carried out by coupling a previously developed and tested system model of fluidized bed combustion (FBC) to an existing radiation model. The predictive accuracy of the coupled code was assessed by applying it to 0.3 MWt METU Atmospheric Bubbling Fluidized Bed Combustor (ABFBC) Test Rig burning lignite in its own ash and comparing its predictions with the measured temperatur...
Characterization of zeolite membranes by gas permeation Soydaş, Belma; Kalıpçılar, Halil; Department of Chemical Engineering (2009) Zeolite membranes are attractive materials to separate gas and liquid mixtures. MFI is a widely studied zeolite type due to its ease of preparation and comparable pore size with the molecular size of many substances. In this study MFI type membranes were synthesized over porous α-Al2O3 supports and characterized with XRD, SEM and gas permeation measurements. In the first part of this study the effect of soda concentration of the synthesis solution on the membrane morphology and crystal orientation was inves...
