Kinetic analysis of catalytic reactions is essential for understanding rate behavior as well as the reaction mechanism. Developing knowledge of intrinsic reaction kinetics and of rate equations is central to reaction engineering studies...
For a perfectly mixed reactor with a predefined constant temperature, the reacting system’s energy balance is not needed to describe the system behavior. The behavior is defined as the composition and the production or consumption of...
In concentrated gases and liquids, where the concentrations of species are of the same order of magnitude, there is no obvious solvent-solute relationship. Fick’s law for diffusion accounts only for one-way solute-solvent interactions...
The hydrolysis of propylene oxide into propylene glycol is an important chemical process with 400,000 metric tons produced worldwide each year. Propylene glycol finds wide application as a moisturizer in foods, pharmaceuticals, and...
This model shows how to use the Parameter Estimation feature in the Reaction Engineering interface to find the Arrhenius parameters of a first order reaction where Benzene diazonium chloride decomposes to benzene chloride and nitrogen.
This model shows how to use the Parameter Estimation feature in the Reaction Engineering interface to find the rate constant and reaction order for the gas phase decomposition of di-tert-butyl-peroxide.
In this example, we study the diffusion of a chemical species through a membrane. The system is used to measure the permeability of gases in membranes. The permeability of the membrane is measured by introducing the species of...
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...
Tubular reactors are generally modelled with the assumption that the concentration and temperature gradients only occur in the axial direction. The only transport mechanism operating in this direction is the overall flow itself, which is...
This model simulates the catalytic abatement of a volatile organic compound (VOC), in this case a contaminant in a waste gas. An analytical expression describes the velocity profile in the free channel, while reaction occurs in the...
