Problems solved by technology

Since the catalyst particles cannot pass through the small bed support gap, these particles are likely to block the distributor or bed support, resulting in uneven distribution of fluid, especially gas, which affects the distribution of fluid in the reactor and affects the reaction process. adversely affect

Example Embodiment

[0049] Example 1

[0050] Using the up-flow reactor of the present invention (two catalyst beds and two floating hydrogen-supply filter dust layers are arranged in the reactor), the feedstock oil is introduced as the reactor feed into the up-flow reactor (the reactor size is 100mm), the hydrogen is divided into two streams and introduced into the first floating hydrogen supply filter layer and the first floating hydrogen supply filter layer. The first floating hydrogen supply filter layer and the second floating hydrogen supply filter layer have membrane modules. The hydrogen gas is dispersed into 50nm-sized microbubbles. The reactor is filled with the first floating hydrogen supply filter layer 180mm, the first catalyst bed 400mm, the second floating hydrogen supply filter layer 100mm, the second catalyst bed 600mm, and the ceramic ball layer 100mm in sequence along the material flow direction; 1 The floating hydrogen supply filter layer includes a slideway and a hydrogen suppl...

Abstract

The invention discloses an up-flow hydrogenation reactor and application thereof. The reactor comprises a reactor shell, and a floating hydrogen supply dust filtering layer and a catalyst bed layer are arranged in the reactor shell in the material flowing direction; a liquid-phase material inlet is formed in the bottom of the reactor shell, a reaction material outlet is formed in the top of the reactor shell, and a hydrogen inlet is formed in the side wall of the reactor shell. The floating hydrogen supply dust filtering layer is arranged in the reactor; hydrogen supply between catalyst bed layers and dust filtration are ingeniously combined, so the hydrogenation reaction degree can be effectively controlled, the reaction efficiency and the reaction uniformity are improved, meanwhile, abrasion among catalyst particles in the reaction process is greatly inhibited, catalyst dust is removed in situ, the service life of a catalyst is prolonged, rising of pressure drop of a catalyst bed layer is greatly slowed down, and long-period stable operation of a liquid-phase reactor is maintained.

Description

technical field [0001] The invention belongs to the field of petrochemical equipment, and relates to an upflow reactor and its application. Background technique [0002] In the field of petrochemical industry, hydrogenation process is an important technical means for processing distillate oil and secondary processed oil. Through hydrogenation, impurities such as sulfur, nitrogen, metals, colloids, and residual carbon in oil products can be effectively removed. Removal and hydrogenation of unsaturated hydrocarbons to saturated hydrocarbons. According to the type of reactor, the hydrogenation process can be divided into fixed bed hydrogenation process, suspension bed hydrogenation process and ebullated bed hydrogenation process, among which the fixed bed hydrogenation process is the most widely used. [0003] According to the feeding method of the fixed bed reactor, it can be divided into two types: upflow type, that is, bottom feed and downflow type, that is, top feed fixed ...
