Abstract

A thermodynamic equilibrium approach is used in a gasification process in order to create a model and program, via MATLAB, that calculates the composition of the product gas and the gasification temperature. The model is flexible, taking in diverse biomass feedstock, as well as a variety of gasification agents. Through equilibrium reactions and mass balances, the syngas composition is calculated. Then, energy balance calculates the gasification temperature using an iterative method. The model and program were created, and then the program was verified through convergence and validated with experimental data from other papers. Finally, a parametric study was run in order to examine the effects on syngas composition caused by gasification temperature, biomass moisture content, amount of air input, and carbon content of the feedstock. The model will be used to optimize converting municipal waste to energy and syngas, which is a prime example of converting waste to wealth.

Biography

Alexandra Slimmer is a junior in Chemical Engineering from Wildwood, MO. She works for the chemical engineering department as a research assistant and MATLAB programmer and for the Missouri S&T Yearbook as a photographer. Her research focuses on biomass gasification. Outside of class, she is the president of the campus chapter of Habitat for Humanity and is a member of Phi Eta Sigma and The National Society of Leadership and Success. Alexandra is currently in the process of being initiated into Tau Beta Pi and Kappa Mu Epsilon and hopes to continue working with biomass gasification and alternative energy in the future.
