Catalysts are common in chemical reactions and reactors. You can also read about them in the Principles of Green Chem. & Eng. They can either be continuously added (and lost as waste) or they can be permanently fixed in the reactor. We will use the permanently fixed kind as they are easier to deal with.

Cаtаlysts аre cоmmоn in chemical reactiоns and reactors. You can also read about them in the Principles of Green Chem. & Eng. They can either be continuously added (and lost as waste) or they can be permanently fixed in the reactor. We will use the permanently fixed kind as they are easier to deal with.
