Objetivos

The aim of the curricular unit is to supply the students with a general panoramic of the biofuels field, namely, of solid, liquid and gaseous biofuels, giving also a perspective on the present and future of bioenergies. It is intended that the students learn the sources and main properties of biomasses used as row materials to produce the different biofuels in relation with the technologies used. Finally students must be able to perform simple calculations related with the unit operations involved in the production of the biofuels studied.

Programa

1. Introduction to the basic concepts related to bioenergies. The context of the present development of bioenergies and social and environmental questions of biofuels production; Concept of biorefinary and the possibility of combining environmental remediation with energetic recovery of bioresidues. Problems related to the seasonality of the avaiability of biomasses and the storage of bioenergy; Portuguese, european and world biofuels market.
2. Solid biofuels: Thermochemical processment of biomasses: combustion; pirolysis and gasification; biochar; Fisher-Tropsch process and reforming of the "syngas" obtained from biomass gasification to produce liquid biofuels; pelletization of forestry and agricultural residues; Main unit operations and equipments. 3. Liquid biofuels: bioethanol and alcoholic fermentation; biodiesel and esterification and transesterification of vegetable oils and fats; the "green diesel" and the hydrogenation and cracking of vegetable oils; main raw materials and processing technologies; main unit operations and equipments.
4. Gaseous biofuels: biogas, biomethane and e bio-hydrogen; biochemical processing of biomasses, anaerobic digestion; technologies used in the purification of biogas; processing of agro industrial residues, municipal solid wastes and WWTP slurries by anaerobic digestion and co-digestion; Introduction to the electrochemical processing of residual biomasses; main raw materials and processing technologies; main unit operations and equipments.
