What is Reactor Space time ?

Space time of the reactor is the time necessary to process one volume of reactor fluid at the entrance conditions. The Reactor Space time is the inverse of space velocity. The Space Time and Space Velocity is a proper measure of performance of the flow reactors. For constant density systems the space time and holding time are the same but are not for variable density systems.

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.

How to Calculate Reactor Space Time?

Reactor Space Time calculator uses Reactor Space Time = Reactor Volume/Volumetric Flow Rate of Feed to Reactor to calculate the Reactor Space Time, A Reactor Space Time is the time necessary to process one volume of reactor fluid at the entrance conditions. This is the time it takes for the amount of fluid that takes up the entire volume of the reactor to either completely enter or completely exit the reactor. Reactor Space Time is denoted by 𝛕_Reactor symbol.

How to calculate Reactor Space Time using this online calculator? To use this online calculator for Reactor Space Time, enter Reactor Volume (V_reactor) & Volumetric Flow Rate of Feed to Reactor (v_o) and hit the calculate button. Here is how the Reactor Space Time calculation can be explained with given input values -> 0.249 = 2.49/9.8.
