Since both descriptions lead to the same expression for α, the same 1/S correction is recovered regardless of the standard state’s pressure. As an aside, the 1/S correction factor for gas can also be derived from the law of mass action,17,78,85 which states that, for an ideal gas ...
The catalysts could promote the secondary gas-phase reactions by nitrogen and surface reactions on the nanocatalyst. The oxidation reactions were presumably enhanced, leading to different decomposition behaviors of AP under different pressure conditions. As shown in Table 8, the nano-sized Cu, Ni,...
In this case, the first process leads to an initial pressure that is not the measured pressure in the dosing volume before opening the valve. In low pressure experiments it is possible to assume ideal gas behaviour and \(c=\frac{P}{{R}_{g}T}\). If the pressure equilibrates before ...
and primary pore size, BET, BJH, MP, andt-plot methods were utilized. They were computed using equipment of BELSORP Mini-II model from BEL Japan utilizing N2adsorption at 77 K as the adsorption temperature, and 89.62 kPa saturated vapor pressure on the PPAC surface area per unit mass of ...

These days, approximately 90% of the world’s all out Zn is produced by customary techniques such as roast–leach–electrowinning and pressure hydrometallurgy from sphalerite [3, 4]. Extracting Zn using traditional methods is difficult and expensive because sphalerite is generally associated with ...
the residence time is defined as the ratio between the reactor volume in the quasi-isothermal section and the gas flow rate (m3/s) under the conditions of temperature and pressure in the reactor. c the equivalence ratio was defined by considering the following stoichiometric equation: H2S + 1.5...
where 𝑷0=𝑝0𝑰 denotes the pressure tensor of an ideal gas. In the well-balanced free-energy model [30], the interaction force is defined as 𝑭=−𝜌∇𝜇𝑐 (15) in order to eliminate the force imbalance at the discrete level. The only remaining task is to determine ...
In their work, the complete steady-state N–S equations with some assumptions are solved by using the Semi-Implicit Method for Pressure Linked Equations (SIMPLE) pressure correction method. It is found that fluid motion and heat transfer can be attenuated by the Coriolis forces. King et al. ...
