Liquid BiofuelsLaajuus (6 ECTS)

Objective

The student knows the properties of biomass (lignocellulose, starch, triglycerides, algae, terpenes, rubber), their abundance, growth rates and conversion of these raw materials into liquid transportation fuels. The student learns basics of engineering, economic and environmental issues related to liquid biofuel production. Furthermore, the student knows physico/chemical processing of biomass to obtain liquid fuels, properties of the raw materials and liquid biofuels.

Content

1. Biomass properties

2. Processing of biomass into liquid fuels. Syn-gas chemistry, bio-oils, hydrodeoxygenation, sugar conversion into fuels, ethanol production, zeolite upgrading, aqueous-phase processing, supercritical reforming, conversion of nonsugar monomers derived from lignocellulose. Triglyceride conversion: transesterification, pyrolysis, hydrotreating, microemulsions and cosolvent vegetable oil blends, glycerol utilization.

3. The economics and environmental aspects of biofuel production as well as related legislation. Future prospects, standards, use of biofuels in vehicles and engines.

4. Project or laboratory work
