Learning Outcomes

Having successfully completed this module you will be able to:

• Discuss possible methods of reducing CO2 emissions and analyse their respective merits
• Assess the likely sustainability of medium and large scale chemical and energy related processes.
• Review the availability of alternate solvents and make informed choices based on Chemistry principles
• Discuss the role of porous architectures in the context of driving selectivity in chemical transformations.
• Understand the chemistry of nuclear power generation, and extraction of metals
• Evaluate the role of CO2 and other greenhouse gases in climate change, and be able to reproduce a simple atmospheric model
• Elucidate the nature of catalytic processes and their impact in the context of Green Chemistry (E-factor, atom efficiency, F3 factory).
• Rationalise the availability and utilisation of renewable feedstocks and their influence on energy efficiency and the environment
• Discuss how energy and chemical feedstocks can be sustainably sourced from either coal or biomass

1) Energy and materials demands on natural resources – population and economic growth. Assessment of energy demand and supply. Carbon and nitrogen cycles. Peak Oil. Medium term sustainability. Climate change and climate modelling. 2) Mainstream inorganic materials: eg. Iron and aluminium. Chemistry of manufacture.
