Modeling of an Enzyme-Based Biofuel Cell Anode

Enzyme-based biofuel cells (EBFCs) use biomass and specific enzymes known as biocatalysts in order to convert chemical energy into electrical energy. At the anode of an EBFC, the biomass (substrate) is oxidized to produce protons and electrons. Mediators are used in the anode to shuttle the electrons from enzymes to electrodes. At the cathode, the oxidant (oxygen) reacts with the protons and ...

Creating a Phase Envelope with a Multicomponent Flash Calculation

* A flash calculation is an equilibrium calculation of a system where several components (species) and phases are present at the same time. This is a demonstration how to use the thermodynamics interface to make flash calculations from data provided external thermodynamic databases. The system in this model is Methane/Ethane/Propane, which would require 3D surfaces to plot the phase envelope. ...

Danckwerts Benchmark

This model compares the solution to the model equations of a tubular reactor using Danckwerts inlet and outlet conditions. A second almost identical model is defined with extra inlet and outlet sections where no reactions occur. The concentration at the beginning of the inlet section is fixed. The results with Danckwerts conditions and with fixed inlet concentrations are compared.

Space-Dependent HI Reactor

This model deals with a reacting system comprising of an equimolar mixture of hydrogen and iodine gas which is allowed to react and form HI. Composition and temperature are allowed to vary both in space and time. This means that you have to define material balances, energy balances, and transport properties in the Reaction Engineering interface. These balances and properties are exported to ...

Nonisothermal HI Reactor

In the case of a perfectly mixed nonisothermal system, you have to set up both the time-dependent material and energy balances. There are no spatial concentration gradients because the system is perfectly mixed, so the Reaction Engineering interface can create a model without evaluating the material-transport properties.

Competing Reactions

Tutorial model of a set of two competing reactions. The model demonstrates: - A good modeling strategy for reaction engineering - How to go from chemical equations to space-dependent models of reacting flow with a minimum of work.
