A quenching apparatus for a reactor is disclosed. The quenching apparatus includes a quenching unit () and a mixing unit (). The quenching unit includes fluid distribution pipes () which branch off from a central portion of the quenching unit in radial directions and eject quenching fluid, and one or more first fluid outlets () which are formed through the bottom of the quenching unit. The mixing unit includes inclined baffles (), one or more partitions () and a second fluid outlet (). The inclined baffles are respectively disposed under the first fluid outlets. The partitions partition a space between inner and outer sidewalls of the mixing unit into a plurality of separated spaces in which the inclined baffles are respectively disposed. Fluid guided by the inclined baffles and the partitions is discharged out of the mixing unit through the second fluid outlet.

Quenching apparatus for a reactor

Disclosed is a method of manufacturing high-quality naphthenic base oil by subjecting, as a feedstock, light cycle oil (LCO) and slurry oil (SLO) obtained through fluidized catalytic cracking (FCC) to hydrotreating and dewaxing.

Process for manufacturing naphthenic base oils from effluences of fluidized catalytic cracking unit

A method of manufacturing high-quality naphthenic base oils comprising a high aromatic content and a large amount of impurities with a boiling point higher than that of gasoline. High-quality naphthenic base oil may be manufactured from light cycle oil (LCO) and slurry oil (SLO), which are inexpensive, and have a high aromatic content, a large amount of impurities, and which are effluents of a fluidized catalytic cracking (FCC) unit. The method also relates to the pretreatment process of a feedstock, where the amounts of impurities (sulfur, nitrogen, polynuclear aromatic compounds and various metals components) in the feedstock are reduced.
