WebLHSV: I suppose you are talking of liquid hourly space velocity which can be calculated by dividing the hourly volume of feed at 15o C to a reactor by the volume of the catalyst in the reactor. So inverse of LHSV is linked to the residence time. Lower LHSV means increase of the residence time and higher severity of the reactor. WebJan 27, 2024 · Feedstock. The Feedstock was the product in the first reactor of the two-stage process by the Blended oil at the following conditions: the temperature = 613 K, LHSV = 1.5 h −1, H 2 /oil volume ratio = 300 and pressure = 6.4 MPa. Blended oil is composed of 80% straight-run diesel and 20% light catalytic cycle oil, which are provided by Shanghai …
