Depleting oil reserves have encouraged the development of technologies to harness the natural resources to sustain the energy needs. Renewable lignocellulosic biomasses have been focus of many studies but advances in the purification and recovering of the products from the product medium has been...

Current-voltage characterization was carried out on dye sensitized solar cells (DSSCs) with different photoanode areas ranging from 0.01 cm 2 to 1 cm 2 . Surprisingly, we found that the short-circuit current density and the efficiency of the solar cells increased exponentially as the photoaonode...

Hydrolysates from dilute acid pretreatment of biomass contain various biomass degradation products which are inhibitory to enzymes and toxic to microorganisms. One of the main inhibitory compounds is acetic acid which is released from the lignin-hemicellulose matrix in the biomass. Acetic acid at...

Sub- and Supercritical Water Based Processes for Conversion of Algae Biomass to Fuels and Green Chemicals – A Review Philip A. Marrone and Bryan V. Yeh Science Applications International Corporation (SAIC) 60 Wells Ave, Suite 103 Newton, MA 02459 In recent years, there has been increasing...

In the future, it is anticipated that multi-product biorefineries will be used to convert lignocellulosic biomass to fuels and chemicals, in which, it may be possible to use membrane-based separations to recover fuels and various products and to improve energy efficiency. To biochemically convert...

Imidazoles and imidazole-amine hybrids are unique classes of organic solvents that feature properties similar to aqueous amine solvents and ionic liquids (ILs), both of which have received a great deal of attention for CO2 capture applications. However, to date, the utility of the imidazole...

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...

Production of bioethanol from lignocellulosic biomass requires pretreatment of the biomass to hydrolyze hemicellulose, separate lignin and reduce cellulose crystallinity. During the pretreatment by dilute acid hydrolysis, several grams of acetic acid per liter of hydrolysate is generated. Acetic...

Poly(oxymethylene) Dimethyl Ethers as components of tailored diesel fuel - properties, synthesis and purification concepts Jakob Burger 1* , Markus Siegert 2 , Eckhard Ströfer 2 , Michael Nilles 2 , Hans Hasse 1 1 Laboratory of Engineering Thermodynamics, University of Kaiserslautern, Germany; 2...

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...
