HYDROGENATION METHOD AND HYDROGENATION SYSTEM FOR HYDROCARBON OIL

Title:

HYDROGENATION METHOD AND HYDROGENATION SYSTEM FOR HYDROCARBON OIL

Document Type and Number:

WIPO Patent Application WO/2023/131019

Kind Code:

A1

Abstract:

The present invention relates to the field of oil refining and chemical engineering, and disclosed are a hydrogenation method and a hydrogenation system for a hydrocarbon oil. The method comprises the following steps: (1) in the presence of hydrogen, subjecting a hydrocarbon oil raw material to a gas-phase desulfurization reaction in a gas-phase hydrogenation reactor to obtain a gas-phase desulfurization reaction product; (2) pressurizing the gas-phase desulfurization reaction product to obtain a pressurized material flow; and (3) feeding the pressurized material flow into a liquid phase hydrogenation reactor, and subjecting liquid phase components in the pressurized material flow to liquid-phase hydrogenation reaction in a liquid-phase hydrogenation reactor to obtain a liquid-phase hydrogenation reaction product. The method and the system provided in the present invention can achieve a deep hydrogenation effect, and can also simplify the technological process, reduce the reaction severity and improve the chemical reaction efficiency on the whole.
