The liquid hourly space velocity (LHSV) is defined as follows: LHSV is volume of charge per hour by volume of catalyst. LHSV is simply an approximate way of estimating the amount of catalyst one would need to purchase for a given feed capacity and product yield. Liquid hourly space velocities (LHSV) in the range of 2-10 hour are used for light products, while it is 0.2-10 hour for heavy residues.

Liquid hourly space velocity (LHSV) is the relationship between the oil flow rate through the reactor and the quantity of catalyst. The units are barrels/H of oil per barrel of catalyst or cubic meters/H of oil per cubic meters of catalyst. It is one of the dependent variables. For example, if the LHSV is increased, reactor inlet temperature or hydrogen circulation is increased to maintain conversion.
