METHOD OF CATALYTIC HYDROPYROLYSIS WITH BUBBLED LAYER USING LARGE PARTICLES OF CATALYST AND FINE PARTICLES OF BIOMASS CHARACTERIZING REACTOR WITH "ANTI-BRIDGING" Russian patent published in 2018 - IPC C10G1/06 C10G1/08 C10G3/00 B01J8/18 B01J8/34 C10L1/02 

FIELD: chemistry.

SUBSTANCE: hydropyrolysis method of the organic oxygen-saturated feedstock includes: a) the introduction of oxygen-saturated organic feedstock and psevdo-fluidizing gas containing hydrogen, in the reactor of hydropyrolysis with fluidized bed containing the fluidized bed of solid particles containing the catalyst, in terms of hydropyrolysis sufficient for the formation of vapour of the thermal decomposition and hydropyrolysis of the organic oxygen-saturated feedstock; b) removing a vapour product from the product stream, containing essentially fully des-oxygenated hydrocarbon substances. The product stream contains less than about 4 wt % of oxygen. The fluidized bed of solid particles has a depth of more than two diameter of the reactor and contains side panels selected from the group consisting of barriers, obstacles, structures, and their combinations, which are spaced from each other at axial intervals ranging from about one to about two diameters of the reactor, so that the "bridging" has no place in the reactor of hydropyrolysis with the fluidized bed.

EFFECT: increase in the yield of liquid hydrocarbon products with low oxygen content, improvement of the process parameters due to reduction of bridging in the reactor.
