Hydrogen partial pressure in hydrotreating
Web17 mei 2024 · Hydrotreating was performed with the aluminum-cobalt-molybdenum catalyst GKD-202, the granule size is 1-2 mm, the catalyst volume in the reactor is 10 ml. The raw materials and hydrogen came to the reactor from top downward: the diesel fraction was supplied with the high pressure dosing pump; hydrogen supply was regulated with the … Web29 apr. 2024 · Hydrogen partial pressure in the hydrocracker reactor is a basic operating parameter that provides the driving force for hydrocracking reactions. Also, the hydrogen partial pressure has an important effect on the catalyst fouling rate (Figure 3-8). An increase in the hydrogen partial pressure serve to suppress the catalyst fouling rate.

WebHydrogen partial pressure (H 2 PP) plays a significant role in hydroprocessing operations. As a rule-of-thumb, catalyst deactivation rate is proportional to the reciprocal of the hydrogen partial pressure factored by an exponential ranging from 2 to 3: Catalyst … Webpetroleum refining, conversion of crude oil into useful products. The refining of crude petroleum owes its origin to the successful drilling of the first oil wells in Ontario, Canada, in 1858 and in Titusville, Pennsylvania, U.S., in 1859. Prior to that time, petroleum was available only in very small quantities from natural seepage of subsurface oil in various …
Web14 jan. 2010 · The effect of hydrogen partial pressure (H2 pp) on hydrotreating conversions, feed vaporization, H2 dissolution, and H2 consumption was studied in a micro trickle-bed reactor, using a commercial NiMo/γ-Al2O3 catalyst. Heavy gas oil (HGO) from Athabasca bitumen was used as feed. The H2 pp level was set inside the reactor by … Web4 aug. 2003 · The reactor outlet hydrogen partial pressure increases significantly with a corresponding improvement in cycle length to 47-49 months from 33-35 months for Case 7 vs. Case 1.
