6. Frame Analysis in Environmental Conflicts : The case of ethanol production in Brazil
Sammanfattning : Governments and policy-makers are currently dealing with some key issues as energy security in countries dependent on oil imports; global economic development, including increased food production; and controlling global climate change and greenhouse gas emissions. The perception that biofuel could solve these challenges simultaneously has led to the implementation of policy and regulatory mechanisms on the mandatory use of biofuels, resulting in a sharp increase in biofuel production and consumption.

7. Ethanol from lignocellulose : Alkali detoxification of dilute-acid spruce hydrolysates
Sammanfattning : Detoxification of dilute-acid lignocellulose hydrolysates by treatment with Ca(OH)2 (overliming) efficiently improves the production of fuel ethanol, but is associated with drawbacks like sugar degradation and CaSO4 precipitation. In factorial designed experiments, in which pH and temperature were varied, dilute-acid spruce hydrolysates were treated with Ca(OH)2, NH4OH or NaOH. LÄS MER

9. Industrial Bioprocess Developments for Biogas and Ethanol Production
Sammanfattning : Current biofuels face a noteworthy misfortune on commercialization because of its economiccomparison with low-cost fuel from the oil reserves. To compete with gasoline as a fuel, thebiofuels need to be economically feasible and demonstrated on a large-scale. LÄS MER
10. The efficient ethanol engine with cold start capability
Sammanfattning : In light of the world’s growing demand for personal transportation and the decreasing availability of fossil fuels, alternative fuels must be evaluated. Ethanol is a renewable fuel whose adoption could help to reduce the burden of anthropogenic activity on the environment. LÄS MER
