Extraction of carotenoids from Chlorella vulgaris

A combined process for carotenoids extraction and efficient bioenergy recovery from the wet microalgae biomass is proposed. High added-value products could thus be extracted prior a hydrothermal gasification of the algal biomass into synthetic natural gas. The economic sustainability of biofuel production from algal biomass as well as the large energy…

Performance evaluation of gasoline alternatives

In light of the climate change and the fact that surface transportation heavily relies on internal combustion engines, many different alternatives to gasoline have been proposed. Herein, we present a model which allows a quick assessment of the suitability of a certain molecule as replacement for gasoline. Using a global sensitivity analysis, the elemental composition and the vapor heat capacity have been identified as main influencing fuel parameters. A case study using the currently proposed alternative fuels (methanol,…

Methane oxidation over a honeycomb Pd-only three-way catalyst

Natural gas is receiving increasing awareness as fuel for passenger vehicles due to its very low specific CO2 emissions. However, control of CH4 emissions from natural gas combustion in stoichiometric engines requires a specific three-way catalyst (TWC). The understanding of the TWC chemistry of CH4 under the periodic rich/lean reaction…

Biomass, a key pillar in the energy transition

Biomass has great potential in Switzerland for future heat and electricity generation and fuel production. This potential is far from being exhausted. Energy derived from wood, farm manure and waste can be stored and whenever there is no wind or sunshine. For the first time, researchers at the Swiss Federal Institute for Forest, Snow and Landscape Resear…
