1. Supercritical Hydrogenation of Vegetable Oils
Sammanfattning : Vegetable oils were hydrogenated in a supercritical single-phase mixture with propane and hydrogen. The reaction was carried out in a small (0.5 ml) fixed-bed reactor and the influence of different process parameters was investigated. LÄS MER
2. Combustion Chemistry Investigation of Liquid and Solid Fuels
Sammanfattning : The aim of this work was to study the combustion of liquid and solid fuels with the emphasis on intermediates and products. Depending on the structure and the complexity of the fuel different reactors and methods were used. Small-scale laboratory reactors were built and chemical analysis and evaluation methods were developed. Heptane. LÄS MER
3. Acute cardiovascular effects of biofuel exhaust exposure
Sammanfattning : BackgroundAnthropogenic air pollution is a global health problem estimated to contribute to millions of premature deaths. Exposure to biomass smoke is common due to varying sources, such as wildfires, indoor cooking over open fires, and residential heating from wood stoves. LÄS MER
4. Experimental Studies on Using Butanol and Octanol Isomers as Drop-in Fuels for Diesel Engines
Sammanfattning : The increasing importance of transportation in modern societies has caused fossil fuel consumption to increase greatly in recent decades. However, burning fossil fuels in internal combustion engines can lead to high emissions of greenhouse gases, which cause climate change. LÄS MER
5. Experimental evaluation of renewable drop-in fuel blends for compression ignition engines
Sammanfattning : Driven by the need to reduce greenhouse gas emissions while meeting the growing demand for mobility, the transport sector is shifting towards more sustainable and less polluting energy sources. Although vehicle electrification is advancing, it will take decades for electric vehicles to completely replace all current vehicles powered by internal combustion engines. LÄS MER
