Biofuels (Energy)

Butanol has the potential to become a superior renewable fuel, either as a mixture with petroleum derived gasoline or as a stand-alone, neat fuel. The promise of butanol is currently marred by the relatively high cost of production. This paper explores a new and novel approach to the production of...

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...

The development of new biomass sources for alternative fuels has become a subject of increasing importance as the nation strives to resolve the economic and strategic impacts of limited fossil fuel resources on our national security, environment, and global climate. Algae are among the most...

The conversion of C5-C6 sugars into 2-furfural (FA) and 5-hydroxymethylfurfural (HMF) have been considered as key intermediate step in the production of transportation fuels and chemicals from ligno-cellulosic biomass. Typically, the process involves the dehydration reaction of the sugars catalyze...

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...

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...

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...

Coke formation appears as a reason for catalyst deactivation and results in undesirable product selectivity in biomass pyrolysis. However, there is no effective way to separate coke and char in the majority of current approaches, which prevents studying coke formation and therefore the real reason...

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...
