  author={Yuriy Rom{\'a}n‐Leshkov and Christopher J. Barrett and Zhen Liu and James A. Dumesic},
Diminishing fossil fuel reserves and growing concerns about global warming indicate that sustainable sources of energy are needed in the near future. For fuels to be useful in the transportation sector, they must have specific physical properties that allow for efficient distribution, storage and combustion; these properties are currently fulfilled by non-renewable petroleum-derived liquid fuels. Ethanol, the only renewable liquid fuel currently produced in large quantities, suffers from… 
Efficient production of the liquid fuel 2,5-dimethylfuran from fructose using formic acid as a reagent.
Evaluating the usefulness of formic acid for conversions of 5-(Hydroxymethyl)furfural (HMF) found that the diformate ester of BHMF (BFMF) is quantitatively converted into DMF in refluxing THF upon the addition of Pd/C, given the lability of BFMF.
The production of 5-hydroxymethylfurfural from fructose in isopropyl alcohol: a green and efficient system.
In an effort to develop an economically viable HMF synthesis process, an isopropyl alcohol-mediated reaction system for the production of HMF from fructose is disclosed, which avoids the use of large volumes of organic solvent and has a minimal environmental impact.
Ionic Liquids in Catalytic Biomass Transformation
1.1 Alternatives to fossil fuels biomass For the past 150 years, coal, natural gas and petroleum functioned as our main sources of energy and chemicals. They provide an estimated 86% of energy and
One-step catalytic transformation of carbohydrates and cellulosic biomass to 2,5-dimethyltetrahydrofuran for liquid fuels.
Hexose from a wide range of biomass-derived carbohydrates, cellulose, and even raw lignocellulose can be converted into 2,5-dimethyltetrahydrofuran (DMTHF), which is superior to ethanol and has many of the desirable properties currently found in typical petroleum-derived transportation fuels.
