Abstract	Exergy relates to thermodynamic value or usefulness in the universe. In this dissertation, three methods in the realm of "process intensification" are explored to reduce exergy destruction by equipment and processes that are used to convert and upgrade methane. Thermodynamic efficiency of a virtual heat exchanger is improved with a novel method of heat exchanger construction that vectorizes heat flow. A transient process for solar-mixed reforming is explored that shows potential to reduce exergy destruction and performance loss of the solar-reactor due to temperature decrease in times of variable solar availability. And, a microscale-based, integrated reactor/heat-exchanger is built and tested for its ability to reduce exergy destruction by facilitating a variable temperature profile of the reaction across its length.
