From Wet Algae to Liquid Fuels

Mar 20, 2013
Phillip Savage

The presentation provides some general background on biofuels and on the use of algae as a biomass source for making liquid fuels. The presentation focuses on R&D efforts related to processing algae in its wet state, which eliminates an energy intensive drying step.

The Effects of Solvent On Glucose Conversion to 5-Hydroxymethylfurfural

Nov 2, 2012
Xianghong Qian
Cellulosic biomass represents an abundant renewable resource for the production of bio-based products and biofuels. 5-hydroxymethylfurfural (HMF) is a critical and versatile intermediate for converting biomass to liquid alkanes and many other value-added products. However, cost effective conversion...

Evaluation of Organic Rankine Cycle Geothermal Power Plant and Considerations

Oct 19, 2011
Kirtipal Barse
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...
