The predefined plug-flow reactor type is used to model the nonisothermal cracking of acetone. Process considerations are investigated as the reaction is run adiabatically, and as a heat exchanger supplies energy to the reacting flow.
In this model, a solution is pumped through a catalytic bed where a solute species reacts as it gets in contact with the catalyst. The purpose of the model is to maximize the total reaction rate for a given total pressure difference...
Real reactors can be modeled as combinations of ideal reactors. In this example two ideal CSTRs with interchange are used to model a real reactor with one highly agitated region and another region with less agitation. Two parameters,...
This model exemplifies the coupling between flow of a gas in an open channel and in a porous catalyst attached to one of the channel walls. The flow is described by the Navier-Stokes equation in the free region, and using the Brinkman...
This example shows 1D steady-state multicomponent gas diffusion. The diffusion of three gases in a Stefan tube is modeled in 1D. The steady-state mass fraction profiles are calculated. It exemplfies in a simple way manipulation of...
Porous catalyst particles are widely used in the chemical industry and are extensively treated in the chemical engineering literature. The catalyst pellets are, in most cases, fluidized by the action of a gas or liquid flowing through...
Biotechnology is a rapidly growing area in the pharmaceutical sciences. One example of a clinical application is gene therapy, where it is possible to produce proteins in vivo, using the body’s own mechanisms for protein production....
In this example, drug-release from a biomaterial matrix to damaged cell tissue is modeled. Specifically, a nerve guide delivers a regenerating drug to damaged nerve ends. The model involves detailed drug release kinetics, with rate...
The electrophoresis of a mixture containing benzoic acid and chlorobenzoic acid, with sodium acetate as background electrolyte, is studied in a model that includes the transport of the involved species through diffusion and migration. The...
Maximizing product yield is a main task in chemical reaction engineering. This can be especially challenging if the desired product, once formed, can be consumed by further reactions. This example investigates such a series reaction as it...
