Biofuels Course

Duration: 2 weeks
Date: August, 2017 
Venue: IMT - Instituto Mauá de Tecnologia - São Caetano do Sul/SP - Brazil

OBJECTIVES

The awareness regarding pollutants and their adverse health effects and the need to intensify the use of renewable energy sources has created an urgent need for engineers to better understand the biofuels combustion process. To effectively contribute to emission control strategies and design and develop of modern internal combustion engines systems and components, a good understanding of biofuels (bioethanol and biodiesel) production, application and behavior in the engines is necessary. This seminar will bring the forefront themes related to combustion and emissions of biofuels. The participants will have activities in the engine laboratory of Instituto Mauá de Tecnologia, and monitored visits to Brazilian companies that are developing innovative solutions for application of biofuels, and also companies that are producing biofuels.

Upon completion of this Seminar & Workshop, you will be able to:

  • Understand the basic production processes of bioethanol (ethanol from sugar cane) and biodiesel.
  • Identify and describe the important processes in combustion and emission of alternative oxygenate fuels like bioethanol.
  • Identify the formation mechanisms and reduction strategies of pollutant species using biofuels.
  • Recognize the effects of biofuels on engine design and operating conditions.
  • Explain the technology and the logic behind after-treatment of pollutants
  • Identify the underlying laws and principles used in combustion and emission black-boxed computer programs
  • Explain the role chemical kinetics plays in the design of low-emission internal combustion engines using biofuels.
  • Understand the Brazilian green energy matrix and the local legislations regarding pollutants reduction and fuel efficiency.
  • Identify design trade-offs between the use of biofuels and increasing engine performance and durability.
