University of Connecticut School of Engineering Process Design Simulation & Optimization Laboratory


Open positions

Openings are expected for graduate and undergraduate students for the following academic year. Students admitted to UConn, who are interested in joining the group, please contact George Bollas, stating your interests and qualifications. Undergraduate UConn students interested in Independent Research Studies should contact George Bollas directly. Current projects include:

Catalyst Deactivation (Graduate Student)
Project Description: The origins of catalyst deactivation in biomass catalytic pyrolysis are not well-understood. In this project the mechanisms of catalyst deactivation due to coke and char formation will be explored using novel approaches of cheminformatics, pore blocking and model-compound experimental studies.

Novel-reactor systems for chemical-looping reforming and combustion (Undergraduate Student)
Project Description: The future of chemical-looping as a viable process for power generation requires that the process can operate at optimal bed utilization. Undergraduate students will work with models and lab-scale reactors for novel chemical-looping systems. One position is open for the summer of 2014. The student will work with graduate students and existing models and reactors for such systems.

Models for Heat Exchanger Fouling Identification (Undergraduate Student)
Project Description: Fouling of heat exchangers is a subject of high significance in refinery, automotive and aerospace applications. Two positions are open for the summer of 2014 for undergraduate students to work with a graduate student in modeling and predicting the fouling of plate-fin cross-flow heat exchangers

Chemical-cooling using CO2 (Undergraduate Student)
Project Description: A lot of research effort is devoted on the carbon dioxide capture and sequestration. However, the fate of the captured CO2 is uncertain. This project focuses on the chemical recycling of carbon dioxide into a valuable, renewable, and inexhaustible carbon source of the future. The overall aim of the project is to explore sustainable carbon cycles of fuel production and consumption by focusing on concentrated CO2 conversion, instead of the newly proposed approaches of storage. Process engineering flow-sheeting software such as ASPEN Plus will be used to model carbon neutral processes for liquid fuels production using CO2 as a carbon source.

Power generation using combined turbines and fuel cells (Undergraduate Student)
Project Description: The PDSOL group has been working on the evaluation of process options for advanced Coal-Biomass-to-Liquid (CBTL) systems, including fuel cells (FC), CO2 and sulfur species capture, and combined cycle (CC) power generation options. This project will explore scenarios for degrading fuel cells to quantify the corresponding penalty on the overall process efficiency. To account for the immaturity of fuel cells in the large application of CBTL-IGFC, FC and CC options in parallel will be explored, as far as their long-term efficiency is concerned. The study will be performed in Aspen Plus.
