FILTER DISK FOR REACTOR WITH FIXED LAYER AND WITH SIMULTANEOUS DESCENDING FLOWS OF GAS AND FLUID Russian patent published in 2011 - IPC C10G49/00 B01J8/02 B01J8/04 

FIELD: oil and gas production.

SUBSTANCE: here is disclosed device for filtration and distribution of gaseous phase and liquid phase, corresponding to charge unit, and feeding reactor containing at least one stationary catalytic layer. Also, the reactor operates under mode of gas and liquid flows descending simultaneously; as a rule, liquid phase contains contaminants. The said device has a disk installed downstream a flow before the stationary catalytic layer. The disk is formed in essence in horizontal plane of a base rigidly tied with walls of the reactor; in the base there are secured in essence vertical channels open at their upper ends for inlet of gas and open at their lower ends for discharge of gas-liquid mixture designed to feed the catalytic layer arranged downstream behind it. At certain height the channels have a continuous side slit or side orifices for supply of liquid. The disk retains the filter layer enveloping the channels; the layer is formed with at least one layer of particles with dimensions less or equal to particles of the catalytic layer. Additionally, here is disclosed implementation of the above described device for filtration and distribution in the reactor of hydraulic processing, for selective hydrogenisation or conversion of residues of hydrocarbon fractions with amount of carbonic atoms within the range from 3 to 50, preferably, in the range from 5 to 30.

EFFECT: trapping contaminants in liquid charge, which feeds reactor; also, reactor, functioning with flows of gas and liquid descending simultaneously.
