Hydrogen partial pressure in hydrotreating
WebThe values of reactor temperature, hydrogen partial pressure, and treat gas-to-oil ratio must be set and controlled with extreme accuracy. The typical coker naphtha hydrotreating reactor loop has three stages. The first stage selectively saturates diolefins to olefins, which react quickly at high temperatures. 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 …

Web15 feb. 2024 · Climate change calls for a paradigm shift in the primary energy generation that comes with new challenges to store and transport energy. A decentralization of energy conversion can only be implemented with novel methods in process engineering. In the second part of our work, we took a deeper look into the load flexibility of microstructured … 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 …
WebAs the amount of hydrogen in the feed gas is reduced, the pressure of the feed must be increased to keep a constant partial pressure of hydrogen. Through the use of a hydrogen management program (starting with measurement of hydrogen purity), overall pressure can be reduced taking a load off compressors. Web7 apr. 2024 · Given that the SMR process and other hydrogen production processes, such as autothermal reforming (ATR) and partial oxidation (POX), produce CO2 as a byproduct, coupling it with carbon capture utilization and storage (CCUS) improves the decarbonization profile. SMR and ATR differ in how heat activates the endothermic steam reforming …
