KE2050 Environmental Catalysis 6.0 credits

The course gives an in-depth knowledge of modern emission reduction technologies using catalytic methods. The course includes subjects such as characterization of emissions, health effects, introduction about internal combustion engines and their history, pollutant formation, test cycles, emission standards, influence of fuel on emissions, motor fuel history, exhaust gas catalysts for different kinds of vehicles, control of stationary emissions (VOC, NOx, SOx), design of units for abatement of nitrogen oxides and VOC, catalytic combustion, production of motor fuels with low content of sulfur and aromatics, hydrogen generation from various fuels for fuel cell vehicles and for emission abatement, market aspects, and green production.

Content and learning outcomes

Course contents

The course gives an overview of chemical processes that employ catalysts to control the emissions of environmentally unacceptable compounds and the course also covers processes which eliminate the formation of such substances. A special emphasis will be put on abatement of emissions from mobile sources. New and emerging catalytic technologies will be given special attention. The general concepts will be covered in lectures, while detailed studies will be performed in supervised seminar assignments. The assignments cover current problems in industry or in the society. These will be presented orally at seminars as well as in a technical paper. The entire course is given in English.

Intended learning outcomes

The overall aim of the course is to develop skills to creatively solve air pollution problems in industry or in the society by either abating the emissions of environmentally unacceptable compounds or employing processes which eliminate the formation of such substances.

After approved course you should be able to

• characterize the most important emissions of hazardous compounds and their health effects

• propose a suitable method to reduce emissions of hazardous substances from mobile or stationary sources from given data

• explain the function of spark-ignition engines and diesel engines and how emissions are formed in these engines both emanating from fuel and from combustion principle

• choose a suitable emission reduction technology for contemporary low-emission vehicles

• explain the role of the catalyst in environmental catalysis and identify its constraints

• explain how commercial catalysts are prepared

• describe the most important methods for abatement of volatile organic compounds and nitrogen oxides in stationary applications

• describe the production of low-sulfur fuels by ultra-deep hydrodesulfurization

• explain how to generate hydrogen from various fuels and how to utilize hydrogen in mobile applications including fuel cell systems

• explain the concept of green production

• write a consistent literature report in English on a subject related to environmental catalysis

• present your ideas and findings in oral form and discuss the results
