What Does GHSV Stand For?

GHSV stands for Gas Hourly Space Velocity

Gas Hourly Space Velocity (GHSV) is a measure used in chemical engineering and catalyst research to quantify the flow rate of gas through a reactor or catalyst bed relative to the volume of the bed. It is defined as the volume of gas passing through the reactor per hour divided by the total volume of the catalyst in the reactor. GHSV is expressed in units such as h^-1 (per hour) and is critical for evaluating the performance and efficiency of catalytic processes, helping to optimize reaction conditions and catalyst design.
