3.2 N2O decomposition over Cs-doped Cu50Ce50Ox catalysts Fig.8. Conversion of N2O over different Cs-doped Cu50Ce50Ox catalysts Conditions: 2600 ppm N2O, balance He, 0.3 Mpa, GHSV-19,000 h-1. Fig.9. The T50 and T100 of different Cs-doped Cu50Ce50Ox catalysts The activities of the catalysts with different Cs content for N2O decomposition are shown in Fig.8, and the T50 and T100 (the temperature at which 50% and 100% conversion of N2O decomposition is achieved) are shown in Fig.9. It’s found…

2.2. Instrumentation The residual concentration of metal ion in the filtrate were analyzed by GBC, Sensaa Series Atomic Absorption Spectrometry (computerized AAS) with air-acetylene flame under the optimum instrumental conditions as shown in (Table 1). The solution pH was measured using digital pH meter (Hanna instrument model HI 8519, Italy). Fourier transform infrared (FT-IR) spectra were measured on Nicolet is 10 FTIR spectrometer in the range of (4000 to 400 cm-1). Scanning electron…

Mathematical model Heat and mass transfer properties of counter flow wet cooling tower are obtained through the balance of mass and energy equations. The assumptions made for deriving the governing equations are listed below [14, 15]: • Heat and mass transfer take place only normal to the flow direction. • Heat transfer to the environment through the walls are negligible. • Heat transfer from cooling-tower fan is negligible. • Specific heats of water and dry air are constant. • Heat and mass…

electricity from one end to another. It hinders the free flow of electrons from atom to atom and molecule to molecule. This is because the electrons are tightly bond to the atoms leaving no space for there to be any free electrons to transmit electrical energy. Examples of insulators are glass, rubber, wood and paper. Conductor is an object or type of material that can transmit heat, sound, light or electricity. It does this by allowing electrons to flow freely from particle to particle. This is…

Abstract The paper present the investigation on the effect of temperature, time and current density on surface roughness in electropolishing process on 316L stainless steel. The cathode material under study was 316L stainless steel. The electrolyte was composed of sulfuric acid, phosphoric acid, and DI water. Full factorial design method was used. ANNOVA technique has been used to assess the quantitative influence of the different process factors of the EP. The surface roughness will be…

1. Derive the mathematical expression for the Lorentz transformation equation. relative orientation of the co-ordinate systems indicated in fig.2 A light-signal, which is proceeding along the positive axis of x, is transmitted according to the equation : x - ct = 0 _______ (1). Since the same light-signal has to be transmitted relative to K1 with the velocity c, the propagation relative to the system K1 will be represented by the analogous formula x' - ct' = 0 _______(2) therefore:…

Cool Mints When eating a mint a cool sensation bursts through one's mouth, but is that mint really making their mouth cold, or is it just their mind playing tricks on them? This science fair project is questioning whether or not mints really make one's mouth cold. To test this the theory, the project will include a glass of lukewarm with mints added in every few minutes. How will adding mints in a glass of room temperature water affect the temperature of water? Why does it feel like mints cool…

for of mass attenuation and energy absorption coefficients Most of the tissues of human organs consisting of elements such as H, C, N, O ,Ca ,P, Na, Mg, S, CI ,K ,Fe and I in their elemental composition. We have studied the variation of mass attenuation and energy absorption coefficients with atomic number at different energies for the elements which are constitutes of tissues of human organs. It has been proposed the empirical relations for mass attenuation and energy absorption coefficients…

The Gibb’s free energy change is the driving force and the fundamental criterion of spontaneity. Physical absorption is to be a spontaneous thermodynamic process, mush have a negative value. The thermodynamics parameters of adsorption relaxation strength (Δε) and dielectric…

ROLE OF ELECTROMAGNETIC RADIATION AND BEER LAMBERT’S LAW Electromagnetic radiation Electromagnetic radiatio :– it is a form of energy whose behavior is described by the properties of particles and wave. Few properties of electromagnetic radiation for eg. Its refraction when it passes from one medium to another are explained best by describing light as a wave. Some other properties such as emission and absorption are better explained by treating light as a particle. The correct or exact nature…
