Learning objectives
The course aims to consider the chemical and technological aspects of the industrial production processes of the base organic intermediates (ethylene, propylene, butenes, butadiene, benzene, toluene, xylenes, methanol). A particular attention will be devoted to the industrial utilization of alternative to oil raw materials, such as coal and natural gas, also to produce hydrocarbon feeds useful as fuels.
