Catalyst loading component and loading method thereof

Abstract

The invention relates to a catalyst loading component and a loading method thereof for a catalytic distillation tower, comprising a catalyst basket and a bracket. The catalyst basket consists of a basket body, an upper cover and a bottom support, wherein the upper cover is mounted at the upper end of the basket body; the bottom support is mounted at the lower part of the basket body; the height of the basket body from the bottom support of the catalyst basket to the upper cover is 1.1-2 times of the height of the portiforium part of a cover hood in the catalytic distillation tower; the heightfrom the bottom support to the lower basket body is 1.1-2 times of the height of a down-flow spout above a column plate in the catalytic distillation tower; the bracket is in a frame structure matched with the cover hood; and the bottom support of the catalyst basket is arranged on the bracket. The method is used for the catalytic distillation tower, realizes forcible redistribution of liquid in the tower, prolongs the flowing path of a gas phase and a liquid phase in a catalyst bed, enhances the holdup of liquid in a reaction area and ensures the mass exchange and catalytic effect. The loading method has simple process, convenient operation, improved efficiency, low cost and easy actualization and is helpful to fully exert the action of the catalyst.

Description

technical field [0001] The invention relates to a catalyst packing component for a catalytic rectification tower and a packing method thereof, and the international patent classification number is proposed to be Int.Cl.B01J 19 / 00 (2006.01). Background technique [0002] The unit operation process that combines chemical reaction and rectification separation at the same time is called reactive distillation process. This process can continuously remove the reaction product from the system, and the heat released by the reaction can be used as part of the latent heat of vaporization required for rectification. Therefore, compared with the traditional chemical process, it has high reaction conversion rate, good selectivity, fixed Low investment, low operating costs and other advantages. Since the 1970s, catalytic distillation using heterogeneous catalysts has gradually been established as a branch of reactive distillation. In this process, the solid catalyst that has been proces...

Problems solved by technology

The disadvantage of this method or component is: the catalyst is solid, so the particle size cannot be too large, otherwise the catalyst cannot be fully utilized, but the catalyst particle size is too small and it is easy to be stratified with the filler, which damages the component to exert its catalytic reaction-separation synergy In addition, this component is also prone to channeling in the bed of the rectification tower, which affects its mass transfer, exchange and reaction effects

However, according to the retrieved literature, neither the catalytic rectification filler nor the filling method can satisfy the above three requirements at the same time.
