Abstract

The invention relates to the technical field of petrochemical engineering, in particular to an up-flow hydrogenation reactor provided with multiple subareas, a reactor system and a catalytic hydrogenation technology. The up-flow hydrogenation reactor comprises a reactor shell, a supporting grid is arranged at the bottom in the reactor shell, and a pressurization area is arranged below the supporting grid; the top of the supporting grid is connected with a plurality of up-flow reaction zones which are connected in parallel, the up-flow reaction zones are mutually independent and have the same flow area, the heights and volumes of catalysts filled in the up-flow reaction zones are the same, the top of each up-flow reaction zone is provided with an intercepting grid, and a gas-liquid separation area is arranged on the outer side of the interception grating. The up-flow hydrogenation reactor is provided with a plurality of up-flow reaction zones, so that the gas-liquid distribution difficulty is reduced; the plurality of up-flow reaction zones are mutually independent and have the same reaction volume and the same catalyst volume, so that non-uniform distribution of the radial catalyst of the reactor is avoided.

Description

technical field [0001] The invention relates to the technical field of petrochemical industry, in particular to an upflow hydrogenation reactor with multiple partitions, a reactor system and a catalytic hydrogenation process. Background technique [0002] Ordinary upflow hydrogenation reactors need to be equipped with a distribution plate to improve the uniformity of gas-liquid distribution in the radial direction of the reactor. In order to improve the distribution effect of the distribution plate, it is necessary to increase the pressure drop of the distribution plate, so that the pressure drop of the distribution plate is much greater than the pressure drop caused by the gravity of the bed itself. A typical distribution plate increases the pressure drop of the distribution plate by reducing the gas-liquid flow area on the distribution plate or setting a distribution cap. On the one hand, the structure of the distribution hood is relatively complicated. It is necessary to...
