Title:
DISTILLATE SUPER/SUBCRITICAL FLUID ENHANCED HYDROGENATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/007736
Kind Code:
A1
Abstract:
A distillate super/subcritical fluid enhanced hydrogenation method, comprising: preheating a mixture of a distillate raw material, a solvent and hydrogen, then introducing the mixture into a first-stage fixed bed reactor, carrying out first-stage catalytic hydrogenation in a supercritical or subcritical fluid state, separating a reaction effluent, collecting a hydrogenated oil product therein and obtaining a hydrogen-containing gas and a solvent-containing light fraction; and returning the solvent-containing light fraction to the first-stage fixed bed reactor for recycling. The method improves the solubility and diffusion mass transfer performance of hydrogen in a distillate hydrogenation reaction system, and improves the hydrogenation reaction efficiency of the distillate.
