Design, modeling, and testing of a hybrid solar/autothermal steam gasification process

Abstract

The novel concept of a hybrid solar/autothermal gasification process to continuously produce synthesis gas is investigated. Heat and mass transfer modeling are performed on a simplified design to evaluate performance over periods of varying solar irradiation. Relevant kinetic analyses are performed for combustion and gasification of coal and biomass using thermogravimetric analysis. Detailed heat transfer modeling is performed for prototype testing and validation in a high-flux solar simulator. Results of prototype reactor testing are presented.
