Conference Paper
The thermochemical conversion of coal and biomass to liquid transportation fuels from a synthesis gas intermediate is investigated using an optimization-based process synthesis framework.

Article
A strategic planning optimization model is proposed for a network of natural gas to liquids (GTL) systems, and it is solved using a rolling horizon strategy. The model formulation determines the strategic and tactical decisions of the GTL supply chain over a long time horizon. The decisions to build new GTL refineries may be made over the span of 3...

Biomass-based energy processes pose logistical challenges because of the dispersed nature of biomass resources. A nationwide supply chain optimization framework is applied to a biomass-to-liquid (BTL) system that uses hardwood biomass resources in the United States to produce gasoline, diesel, and jet fuel. Using optimized BTL refineries of differi...

Conference Paper
A significant portion of natural gas resources in the United States is categorized as stranded natural gas since the wells are inaccessible from current pipeline infrastructure. Additionally, the associated gas production from oil operations is either vented, re-injected, or flared. There is a need to monetize these stranded gas resources to channe...
