Up-flow type reactor

Abstract

The invention relates to an up-flow type reactor, which comprises a lower section catalysis reaction zone and an upper section gas-liquid separation zone, wherein 1, 2 or multiple catalyst bed layers are arranged at the lower section catalysis reaction zone, a liquid collection chamber is arranged at the upper section gas-liquid separation zone; the catalyst bed layer can be a stationary bed, a micro-expansion bed and / or an online replacing bed; in the material flowing direction in the reactor, the lower section catalysis reaction zone and the upper section gas-liquid separation zone are in series connection. According to the invention, the functions of the up-flow type reactor and the reactant gas-liquid separator are combined, the structure of the separator is simplified and the separation efficiency is improved; the structure is particularly suitable for a pre-hydrogenation reactor during low and medium temperature coal tar deep hydrogenation modification process; the liquid exhausted from the liquid collection chamber of the separator can be used as circulating oil to return to an upstream process; the rest liquid and / or gas enter / enters a deep hydrogenation modification reactor as a pre-hydrogenation reactant; or the liquid exhausted from the liquid collection chamber of the separator and the gas exhausted from the gas phase space of the separator are subjected to post treatment respectively.
