What is the Reactor Space Velocity?

The Reactor Space Velocity gives us the number of reactor volumes that can be treated per unit time. The Reactor Space Velocity is the inverse of reactor space time. This is the number of volumes of reactor that either completely enters or completely exits the reactor in a unit period of time.

What is Chemical Reaction Engineering?

Chemical reaction engineering is a specialty in chemical engineering or industrial chemistry dealing with chemical reactors. Frequently the term relates specifically to catalytic reaction systems where either a homogeneous or heterogeneous catalyst is present in the reactor. Sometimes a reactor per se is not present by itself, but rather is integrated into a process, for example in reactive separations vessels, retorts, certain fuel cells, and photocatalytic surfaces.
