Abstract

The invention discloses an organic nitrogen and / or organic oxygen-containing hydrocarbon hydro-upgrading method and a combined reactor thereof. The combined reactor at least comprises 2 reaction areas R1 and R2, wherein R1 executes a hydrofining reaction including hydro-denitrification and / or hydro-deoxygenation reaction; R2 executes hydro-upgrading of a refined liquid-phase product, such as arene hydro-saturation, deep hydro-denitrification and hydrocracking; at least one part of the ammonia and / or steam containing gas-phase reaction product R1 PV of R1 does not go through R2 so as to reduce the quantity of ammonia and / or steam going through the R2 catalyst bed layer; the reactors used in R2 at least include a combined hydrogenation reactor R2E; and the R2E is provided with a separation section R1PS for separating R1P and a down-flow type catalytic reaction section R2S and also can be provided with a reaction area R3 for processing a bypass gas R1PV and an R2 reaction product R2P. The organic nitrogen and / or organic oxygen-containing hydrocarbon hydro-upgrading method and a combined reactor thereof are applied to the deep hydro-upgrading process of medium-low temperature coal tar, and the catalyst operation conditions of the reaction area R2 can be optimized.
