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. WebLHSV is another process variable that influences the efficiency of hydrotreating technology and increases the life of a catalyst. Space velocity can be defined as the volume per hour of reactor...

WebThe reactor can be operated as a continuous or batch process, when the hydrogenation reaction could generally take place at 250–350 °C and 3–10 MPa. The liquid product is separated from the gas phase in a separation tank, while the gas stream is fed to a gas purification unit before being recycled to the reactor.

WebCatalysis Science & Technology ก.ค. 2015. The deactivation and regeneration behaviors of Ni/γ-Al2O3 and Co/γ-Al2O3 catalysts in the … WebMar 28, 2024 · Scientist with beakers Liquid hourly space velocity (LHSV), is a method for relating the reactant liquid flow rate to the reactor volume at a standard temperature. … 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. An increase in LHSV implies a hike in the feed flow rate (liquid). According to Raoult’s Law, with the increase of the mole … See more did ge sell out to china
