Upright upflow reactor

Abstract

The invention relates to an upright upflow reactor which is particularly suitable for pre-hydrogenation process of medium/low-temperature coal tar. In the whole material flow flowing direction in the reactor, one or two or more catalyst bed layers can be arranged in the reactor, the catalyst bed layers can be fixed beds and/or expanded beds and/or online replacement beds and/or suspended beds and/or fluidized beds, at least one separator arranged in the vertical direction is arranged in a reaction space inside the reactor, the space on two sides of the separator is relatively separated, the independence is enhanced, long-distance movement in the horizontal direction of air bubbles and/or droplets and/or catalyst particles on two sides of the separator is weakened, the air bubbles in the reaction space are prevented from merging and enlarging, fluctuation amplitude of clear liquid phase height of the bed layers in the vertical direction is weakened, namely imbalance of pressure difference of the bed layers in the vertical direction is weakened. The reactor is simple in structure, feeding distribution imbalance can be effectively weakened, and hot spots on the horizontal section are avoided.

Description

technical field [0001] The present invention relates to a kind of vertical upflow reactor; Particularly, the present invention relates to a kind of upright upflow reactor suitable for the pre-hydrogenation process of medium and low temperature coal tar, in the reactor, the flow direction of the whole stream is upward, and the reaction The reactor can be provided with 1 or 2 or more catalyst beds, and the catalyst bed can be a fixed bed or an expanded bed and or an on-line displacement bed and or a suspension bed and or an ebullated bed, and at least one catalyst bed is set in the reaction space in the reactor The partitions arranged in the vertical direction separate the space on both sides of the partition relatively to enhance independence, weaken the horizontal long-distance movement of bubbles and / or liquid droplets and / or catalyst particles on both sides of the partition, which is beneficial to prevent the merger and growth of bubbles in the reaction space , which is cond...
