Sentence examples for effectiveness factor in from inspiring English sources
An analytical simple algebraic expression for isothermal effectiveness factor in a porous pellet is presented.
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.
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.
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.
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 simplified method to calculate the effectiveness factors in irregular geometries of washcoats is presented.
This paper describes a method for the determination of effectiveness factors in a monolith washcoat of non-uniform thickness.
This paper describes an approximation method for the estimation of effectiveness factors in porous catalysts that have reactions with non-linear kinetic models.
The heat of crystallization will produce non-isothermal conditions close to the crystal surface and effectiveness factors for this non-isothermal case are evaluated based on the analogy with external effectiveness factors in heterogeneous reaction kinetics.
