Sentence examples for effectiveness factor in the from inspiring English sources
With pseudo-steady-state conditions, the conversion of solid becomes analogous to an "effectiveness factor" in the transformed variable.
Since transport resistance limits the effectiveness factor in the reactor to values much less than unity, increasing the catalyst surface area increases its activity.
Transport resistance evaluation revealed that in spite of significant intraparticle diffusion limitation (effectiveness factor in the range of 0.01), the both resistances of mass transfer around the catalyst particle and inside the catalyst pores should be taken into account.
The model is used to demonstrate the influence of network topology (regular vs. random) and pore structure parameters (mean pore size, standard deviation pore size and network connectivity) upon the catalyst effectiveness factor in the presence of a fraction of catalyst pores that are filled with capillary condensate.
We present a general solution of the diffusion reaction problem for linear kinetics and an expression for the effectiveness factor in terms of the shape normalized Thiele modulus for a catalyst particle of arbitrary shape and with an arbitrary activity profile.
When applied to compute the concentration profile and the effectiveness factor in a porous catalyst, the conventional shooting method requires that the concentration at the catalyst center y(0) must be greater than zero to yield a nontrivial solution.
A model to calculate the actual transient effectiveness factor in spherical porous catalyst particles in gradientless reactors, where a first order reaction takes place under isothermal conditions, linear equilibrium adsorption and intraparticle diffusion control, was developed.
It is shown that in the isothermal case, the maximal (minimal) solution has the minimal (maximal) effectiveness factor while in the non-isothermal case, the maximal (minimal) temperature solution has the maximal (minimal) effectiveness factor.
The solution is translated into a global deactivation function over the particle, which is related to the effectiveness factor appearing in the fluid-phase model equations.
