The isotherm was recorded by Micromeritics ASAP 2020 analyzer and the physical adsorption of N2 at the temperature of liquid nitrogen (-196oC) with a standard pressure range of 0.05-0.30 P/Po. 2.3 Catalytic Activity Measurement After annealing the catalyst bed, it was cooled to room temperature in the same conditions as we used for reactive calcination. The CO oxidation was analysis by gas chromatogram to measure the activity of the catalyst. The oxidation of CO was carried out to measure the activity of resulting catalyst. 2CO + O2→2CO2 -------------------- (1) The oxidation of CO was carried out under the following reaction conditions: 100mg of catalyst with feed gas consisting of a lean mixture of 2.5 vol.% CO in air and total flow rate is maintained 60 mL/min.
In the secondary evaporator, the feed seawater 2 was heated up by the mixed steam from the steam ejector, where its temperature is raised from Tf to the evaporating temperature, Ts. The secondary steam from the secondary evaporator splits into two portions: the first part is condensed in the condenser, while the rest is entrained by the steam ejector, where it is compressed by primary steam to raise the pressure and temperature and then it is introduced into the secondary evaporator as the heat source and is completely condensed into liquid. A known mass of fresh water (Mp + Ms) is
In this experiment, the behaviour of water during boiling process is observed. When water is heated to boiling temperature at constant volume, different regimes are observed until it reaches to saturation pressure. If the pressure is above 1.013 bar, the water is supersaturated. The pressure at which boiling occurs is known as saturation pressure. The standard conditions at which water boiling take place are 100C and 1.013 bar.
ΔH= q Specific heat is the amount of heat needed to raise the temperature of one gram of a substance by 1 C (or 1 K).1 Specific heat of water is equal to 4.18 J/ g℃.1 In order to determine the specific heat capacity of metal, it is necessary to know mass and change in temperature, specific heat of water, also change in temperature and mass of metal used: q_(H_2 O)=〖S.H.〗_(H_2 O) × m_(H_2 O) × ∆t_(H_2 O)= -〖S.H.〗_M × m_M ×
Chemical reactions transform bond energy into heat or work. Enthalpy of reaction (Hrxn) is the term used for the change in heat as a reaction is carried out at constant pressure. It is a state function as it only depends on the final and initial conditions during the change of state. If Hrxn < 0, the system releases heat and is therefore an exothermic reaction. On the other hand, if Hrxn > 0, the system absorbs heat.
A heating mantle with three heating plates will be used to heat the soxhlet extractor during the experiment. Filter paper will be used to filter the product from the soxhlet extractor if need be. A rotary evaporator will be used for liquid-liquid extraction. GCMS (Gas chromatography mass spectrometry) will be used to analyze the extract. 3.3.

1.1 Internal Combustion Engine Heat engine are produced from internal combustion engine which converts chemical energy in a fuel into mechanical energy and actually available on a rotating output shaft. Thermal energy is produced from the conversion of chemical energy of the fuel to the thermal energy by means of combustion or oxidation with air inside the engine. The temperature and pressure of the gases within the engine is raised by thermal energy and the high pressure gas then expands against the mechanical mechanisms of the engine. The mechanical linkages of the engine convert this expansion to a rotating crankshaft which is the output of the engine. For the desired final use, the crankshaft is connected to a transmission and power train
