METHOD OF REFINING OIL DISTILLATES Russian patent published in 1997 - IPC

Abstract RU 2072386 C1

FIELD: petroleum processing. SUBSTANCE: oil distillate are successively subjected to hydrofining, hydrocracking, and hydrodearomatization. Processes are conducted at 320-380 C with hydrogen to raw material ratio 300-1000 cu. nm/cu. m, and volume velocity of feed 1.0-10.0 h-1. Hydrocracking and hydrodearomatization are conducted at 2.5-4.5 MPa. Preferable ratio of catalyst charges in hydrocracking and hydrodearomatization stages is 1:9 to 1: 1.1. EFFECT: optimized process parameters. 3 cl
