Project Description

NETL is partnering with Sandia National Laboratories to provide experimental measurements of the reaction kinetics of coal char at high temperatures and elevated pressures. This research will utilize Sandia’s pressurized combustion and gasification reactor to quantify the kinetics of oxidation and gasification under conditions relevant to pressurized circulating fluidized bed reactors and coal gasifiers. This project includes oxidation and gasification kinetics of chars, as well as the influence of pressure on devolatilization and char formation. This project will incorporate kinetic models and data into the Carbonaceous Chemistry for Computational Modeling (C3M) package. The objectives of this research are to generate the validation data necessary for the Sandia kinetic model for oxy-combustion of coal char and a report detailing the incorporation of this kinetic model into C3M.

Project Benefits

This information is needed to improve both the phenomenological understanding and the comprehensive computational fluid dynamics modeling of many technologies including pressurized circulating fluidized bed combustors, entrained flow gasifiers (e.g., Shell, Destec, and Texaco/GE designs), and transport gasifiers (KBR design).
