höyrykatkoksessa
Höyrykatkoksessa, often translated as steam cracking, is a fundamental petrochemical process used to break down hydrocarbon molecules into smaller, more valuable ones. This is achieved by exposing the hydrocarbons to high temperatures, typically between 750 and 950 degrees Celsius, in the presence of steam. The steam acts as a diluent and heat transfer medium, preventing coke formation and promoting the desired chemical reactions.
The primary feedstock for steam cracking includes naphtha, ethane, propane, and gas oils. The process is carried
Ethylene and propylene are the most significant products of steam cracking. They serve as crucial building
