Biofuel production from microalgae by hydrothermal processing

Christian Ludwig, Rizlan Bernier-Latmani, Frédéric Vogel, Jean-Paul Schwitzguebel, Gabriela Anca Haiduc

Introduction: Microalgae cultures represent an attractive source of biomass for biofuel and chemicals production since they can have higher energy yields per area than conventional biomass crops and can be grown on marginal land using waste, saline, or bra ...

Life Cycle Assessment of Soybean-Based Biodiesel in Argentina for Export

Edgard Gnansounou, Arnaud Dauriat, Luis Alberto Panichelli

Background, aim and scope. Regional specificities are a key factor when analyzing the environmental impact of a biofuel pathway through a life cycle assessment (LCA). Due to different energy mixes, transport distances, agricultural practices and land use c ...

The Roundtable on Sustainable Biofuels: plant scientist input needed

Sébastien Haye

The Energy Center at the Ecole Polytechnique Federale de Lausanne (Swiss federal institute of technology) is coordinating a multi-stakeholder effort, the Roundtable on Sustainable Biofuels (http://energycenter.epfl.ch/biofuels), to develop global standards ...

Determination of biodiesel blending percentages using natural abundance radiocarbon analysis: Testing the accuracy of retail biodiesel blends

Jeremy Samuel Arey

Blends of biodiesel and petrodiesel are being used increasingly worldwide. Due to several factors, inaccurate blending of these two mixtures can occur. To test the accuracy of biodiesel blending, we developed and validated a radiocarbon-based method and th ...

Fischer-Tropsch Diesel Production in a WTW Chain Perspective

We calculated carbon and energy flows in 11 models of FT plants. While uncertainties are substantial, our best- guess estimates indicate that FT diesel is economically competitive, with fuel costs comparable to fossil diesel derived from oil at 34 $/bbl fo ...

Estimating greenhouse gas emissions from indirect land-use change in biofuels production: concepts and exploratory analysis for soybean-based biodiesel production

Edgard Gnansounou, Luis Alberto Panichelli

Due to changes in carbon stock of soil and biomass, indirect land-use change (ILUC) has consequences on green house gas (GHG) balance of a biofuel that are not presently considered in evaluation of environmental merits of biofuels. Significant changes in l ...

Biodegradation and environmental behavior of biodiesel mixtures in the sea: An initial study

Jeremy Samuel Arey

Biodiesel, a mixture of fatty acid methyl esters (FAMEs) derived from animal fats or vegetable oils, is rapidly moving towards the mainstream as an alternative source of energy. However, the behavior of biodiesel, or blends of biodiesel with fossil diesel, ...

Using comprehensive two-dimensional gas chromatography retention indices to estimate environmental partitioning properties for a complete set of diesel fuel hydrocarbons

Jeremy Samuel Arey

Comprehensive two-dimensional gas chromatography (GC×GC) provides nearly complete composition data for some complex mixtures such as petroleum hydrocarbons. However, the potential wealth of physical property information contained in the corresponding two-d ...

Optical resolution of phenylalanine by enzymic transesterification

Albert Renken

The acyl transfer of phenylalanine to MeOH by means of chymotrypsin starting from phenylalanine Pr ester has been studied. This transesterification turns out to be useful for producing optically pure phenylalanine esters as well as for the optical resoln. ...
