WebLHSV stands for liquid hourly velocity. It is equal to volume of feed per hour at 15 degree C divided by the volume of catalyst. It signifies the residence time of feed in the reactor. … WebAug 2, 2009 · The space velocity is an indication of the residence time of contact between reactants and catalyst. When the hourly volume charge rate of naphtha is divided by the volume of catalyst in the reactors, the resulting quotient, expressed in units of 1/h, is the liquid hourly space velocity (LHSV). Alternatively, if the weight charge rate of ...
