FIELD: process engineering.
SUBSTANCE: invention relates to catalytic cleaning of green heavy oil distillates. Reactor comprises at least one bed layer, in fact, liquid phase L and, in fact, gas phase G located at reactor bottom and separated by interface 38 and distribution tray furnished with at least one main pipe to circulate liquid phase L in bed direction and at least one channel to feed gas phase G to said bed. Tray has at least one combined pipe to circulate liquid phase in bed direction or to feed gas phase into said bed.
EFFECT: higher quality of cleaning.
