Energy and Biofuels

Recommended Prerequisites

Chemical Thermodynamics; Fluid Dynamics; Heat Transfer; Mass and Energy Balances; Introduction to Chemical and Biochemical Engineering

Teaching Methods

In the theoretical classes it is intended to motivate the students for contents of the course by promoting their participation and by  exposing the topics a clear and understandable way by using audio visual means. In the TP classes discussion the pratical cases is to be carried out. As a complement of the T and TP classes it is intended to do a visit to an industrial site where the topics given are demonstrated in the real world. 

Learning Outcomes

Conhecer as características e condições de funcionamento dos principais equipamentos de produção de energia na indústria e compreender as interações entre os dispositivos presentes numa rede de energia. Dotar os alunos de competências para identificar as principais variáveis ​​nos processos de selecção e instalação dos equipamentos e desenvolvê-las na análise crítica dos sistemas de produção de energia.
- Compreender os compromissos do triângulo energia/ambiente/desenvolvimento económico.
- Comparar a energia fóssil com a energia renovável.
- Conhecer os métodos de produção de bioenergia e biocombustíveis: associados a biomassa, biogás, bioetanol, biodiesel, (bio) hidrogénio, éter dimetílico.
- Compreender os processos de transformação da biomassa lignocelulósica em energia: hidrólise, pirólise e gaseificação.
- Avaliar os combustíveis gasosos e líquidos (fósseis e sintéticos) - caracterização e rotas de produção.
