A Future Energy Supply Based on Liquid Organic Hydrogen Carriers (LOHC)

Oct 18, 2011
Daniel Teichmann
This lecture describes a concept for the establishment of a competitive energy distribution network based on Liquid Organic Hydrogen Carrier (LOHC) compounds. These compounds are characterized by the fact that they can be loaded and un-loaded with considerable amounts of hydrogen in a cyclic...

Lignin Depolymerization and Deoxygenation In Ionic Liquids

Oct 18, 2011
Blair J. Cox
Lignin, an amorphous aromatic biopolymer that comprises up to 30% of plant matter, was dissolved and depolymerized in ionic liquids under acidic conditions. The acidic ionic liquid 1-methylimidazolium chloride (HMIMCl) acts as a combination solvent and catalyst that facilitates degradation of...

Heterogeneous Catalysts in the Dehydration of Fructose to HMF

Oct 18, 2011
Sylvia Reiche
Several crucial steps in the upgrading of biomass-derived raw materials involve acid catalyzed reactions, such as the hydrolysis of cellulose or the dehydration of sugars. Although heterogeneous catalysts are desired in large scale industrial processes, their application is limited by several...

The Role of Oxygen In the Stability of Biomass Pyrolysis Oils

Oct 18, 2011
Foster Agblevor
One of the major challenges in the conversion of biomass pyrolysis to high value products and fuels is the poor stability of the oils. Biomass pyrolysis oils have shown increases in viscosity during storage at ambient conditions and when heated above ambient temperature. The poor stability of the...

Hydrogen Production From Deliquescence of Ammonia Borane

Oct 18, 2011
Bing-Hung Chen
Chemical hydride is one of the most potential hydrogen storage materials which can effectively increase hydrogen storage capacity. To meet the new goal of U.S. department of energy (DoE), 4.5wt% and 5.5 wt% of gravimetric hydrogen density capacity by 2010 and 2015, respectively, ammonia borane (AB...

The Capture of Carbon Dioxide by Ionic Liquid

Oct 18, 2011
Hongyan He
Ionic liquid is one kind of organic salts with negligible volatile pressure which might lead to promising substitute candidates for alkanolamines in separation of carbon dioxide. To satisfy this requirement effectively, task specific ionic liquids with alkaline groups, such as imidazolium cation...
