WebA process is described for hydroconversion of a mixture of organic oils of different origins in a conventional hydrotreatment unit, constituted by at least two catalyst beds, under moderately severe process conditions to obtain diesel fuel oil. The process includes injection of a stream of oil of animal or plant origin, with independently adjusted flow … Webcarried out in a fixed-bed reactor using sulfided catalysts Ni-W/Al2O3 and Co-Mo/Al2O3. The influence of temperature, pressure, liquid hourly space velocity (LHSV) and hydrogen/feedstock ratio on hydrodesulfurization (HDS) and hydrodenitrogenation (HDN) was investigated. Catalytic activities of two catalysts were compared.

As the Liquid Hourly Space velocity (LHSV) is the ratio of the volumetric flow rate (hourly) of the liquid feed to the volume of the catalyst present in the reactor. So, LHSV is reciprocal of the space-time. Reducing LHSV generally results in an enhancement of the hydrotreating reaction. However, an … See more In chemical engineering, space velocity refers to the Space velocity = flow rate of the feeds/ volume of the reactor (or volume of the … See more There are different types of space velocities which are as follows: 1. GHSV, gas hourly space velocity: It is basically the ratio of volumes … See more LHSV, which is the reciprocal of space-time, signifies the time spent in the reactor of the reactants. It was observed that reducing LHSV leads to an increase in the conversion in HDS, HDN, and HDA reactions (see the … See more The higher the LHSV the faster will be the vaporization of feed as well as H2 dissolution.
