The objective of this work is to evaluate the feasibility of an Organic Rankine Cycle (ORC) power plant to generate electricity from low flow rates of a geothermal resource (~875 gpm) at low temperatures (T~100°C). A model of ORC was developed using HYSYS process simulator. DOE’s Cost of Renewable...

Glycerol produced as a waste product in biodiesel production has interesting potential as a low-cost biomass-derived feedstock for chemical processing. A process of current academic and commercial interest is the acid-catalyzed dehydration of glycerol to acrolein, a valuable platform chemical. Such...

Hot water extraction of bitumen from oil sands has been commercially applied for decades. The extraction process is greatly aided by the addition of caustics and other reagents, which adversely impact handling and disposal of byproducts at process end. Recent effort of increasing energy efficiency...

Research within the Great Lakes Bioenergy Research Center aims to better understand the bottlenecks associated with bioconversion of lignocellulose to liquid transportation fuels, knowledge which will then be used to improve the efficiency of this process. Much of these studies are currently...

Over one fifth of calories consumed by humanity are from rice. Consequently, vast quantities of rice hulls are disposed of as waste, since the hull constitutes 20% of rice mass. Standard practice for disposal of rice hulls is burning, generating pollution and CO 2 , or thrown away in vast...

The US Air Force has committed to an alternative aviation-fuel initiative to implement a roadmap for testing and certifying alternative fuel components including biomass-derived alternatives produced from non-food plants, animal fats, and algae, as well as synthetic fuel components derived from...

One-dimensional semiconductor materials have attracted significant research interest because of their unique properties for various technological applications. SnO 2 , as a wide band-gap semiconductor material is a promising photoanode material for dye-sensitized solar cells because of its fast...

Argonne’s Model for Universal Solvent Extraction (AMUSE) simulates multi-stage aqueous solvent extraction processes for components of interest to spent nuclear fuel reprocessing. The current work has incorporated time dependency into the simulation; the original AMUSE program was used for steady-...

Some processes aimed to biofuels production, use lignocellulosic wastes as feedstocks for fermentative conversion. If this is the case, pretreatment is required to make these resources fully digestible. Among a wide range of pretreatment options, this study focuses and compares oxidative-alkaline...

Advanced biofuels or drop-in fuels is the terminology used to refer to hydrocarbon fuels that are direct replacements or supplements for existing gasoline, diesel and jet fuels currently refined from conventional petroleum feedstocks. Drop-in fuels from biomass will need to meet all of the refinery...
