Chemical Percolation Devolatilization (CPD) Nitrogen and Light Gas (NLG) Model
A modified verion of the CPD model has been completed that calculates nitrogen
release in the tar and light gas, and also the amount of nitrogen remaining in
the char. This model was developed by Dominic Genetti (MS, BYU, 1999). In
addition, this model uses a correlation to calculate the mass fraction of major
light gas species in the light gas fraction as a function of time, using a table
look-up procedure. Thus, the computational eficiency of the CPD model is
maintained, and the number of ODE's solved in the code is minimized.

I am trying to generate a user database for the CPD model. If you would like free updates on improvements to the CPD model and related correlations, please send me an email: tom@harvey.et.byu.edu.
