Abstract

The invention discloses a preparation device used for refining olefin catalysts of reforming oil. The device comprises a reaction flow guiding device and a liquid collecting box. The reaction flow guiding device is arranged on the top of the liquid collecting box and is in the shape of a funnel, the reaction flow guiding device comprises a rectangular upper portion and a conical lower portion, the upper portion and the lower portion are communicated through a through hole, material inlets are formed in the two sides of the upper portion, a movable rubber plug is arranged in the upper portion, the movable rubber plug and the upper portion are at equal height, the edge length of the movable rubber plug is larger than the diameter of the through hole, and a material outlet is formed in the bottom of the liquid collecting box. Compared with the prior art, the position of the movable rubber plug is determined through the number of materials added into the two edges of the flow guiding devices, it is guaranteed that the ratio of the materials entering the liquid collecting box is in a dynamic balance state, and it is avoided that local concentration is too high and reaction is too slow.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a preparation device for a reformed oil refining de-olefin catalyst. Background technique [0002] The adsorbent used in the adsorption and separation process of the isomerization unit in the aromatics complex is very sensitive to olefins. Even if the content of olefin impurities is only a few parts per million, it will have a very adverse impact on the process. In order to protect the adsorbent, generally in the second There is a refining process before the toluene tower to remove trace olefins contained in each feed. The content of reformed oil olefins in each feedstock of the xylene tower is the highest, which is the focus of refining. Each component in the catalyst needs to react while adding to avoid excessive intermediates affecting the catalytic effect, while the traditional stirred reactor has a long reaction channel which is not conducive to the reaction spe...
