Definition - What does Dehydrogenation mean?
Dehydrogenation is a chemical process in which a hydrogen atom is removed from a molecule of an organic compound. It is the opposite of hydrogenation process. The analysis of chemical reaction in dehydrogenation process is performed first in the laboratories. Once the required output is obtained in the labs, then the same process is repeated in the industrial process on a large scale for production of styrene in very fine chemicals, petrochemicals, and detergents.
Petropedia explains Dehydrogenation
Dehydrogenation reactions are performed in the production of styrene at large scale. Styrene is produced when dehydrogenation of ethyl benzene takes place. The catalyst used for dehydrogenation process is based on Ferrous oxide along with a slight percent of potassium oxide or potassium carbonate.
C6H5CH2CH3 ---> C6H5CH=CH2 + H2
When dehydrogenation using oxygen as an acceptor is considered, then formaldehyde is produced by methanol catalytic oxidation. In the formox process, methanol and oxygen react at temperatures of 250 to 400 degree Celsius in the presence of ferrous oxide along with vanadium or molybdenum for the production of formaldehyde as per the chemical equation below:
2 CH3OH + O2 ---> 2CH2O + 2 H2O
