A kind of multistage fixed-bed reactor for the reaction of synthesizing n-propanol

Abstract

The invention discloses a multi-stage fixed bed reactor for an n-propanol synthesizing reaction. The multi-stage fixed bed reactor comprises a fixed bed reactor body, a plurality of catalyst beds, a first inlet pipe and a plurality of second inlet pipes, the multiple catalyst beds are arranged inside the fixed bed reactor body, turnover devices are arranged on the outer sides of the multiple catalyst beds correspondingly, and the output ends of the turnover devices are rotatably connected with the fixed bed reactor body; and the first inlet pipe is fixedly connected to one end of the fixed bedreactor body. According to the multi-stage fixed bed reactor for the n-propanol synthesizing reaction, the turnover devices are additionally arranged on the outer sides of the multiple catalyst beds,after the catalyst beds react for a period of time, catalysts on the catalyst beds can fully react, and the reaction efficiency of the catalyst beds is improved; shock absorption protection devices are arranged inside the first inlet pipe and the multiple second inlet pipes correspondingly, thus the protective effect is achieved on the inlet pipes, then the service lives of the inlet pipes are prolonged, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of fixed-bed reactors, in particular to a multi-stage fixed-bed reactor for synthesizing n-propanol. Background technique [0002] Fixed bed reactor refers to the filling of granular solid catalyst or solid reactant in the reactor to form a stacked bed of a certain height. While the gas or liquid material flows through the static fixed bed through the particle gap, a heterogeneous reaction process is realized. . [0003] In the prior art, in the process of n-propanol synthesis, a multi-stage fixed-bed reactor is used, which is divided into multiple catalyst beds, which is quite connected with multiple reactors in series, and depends on the different temperatures of the inlet and outlet of each bed, and the Different gases are introduced for adjustment, and when the gas is introduced, a certain airflow intensity will be generated, which will generate a certain frequency of vibration at the entrance and exit ...

[0003] In the prior art, in the process of n-propanol synthesis, a multi-stage fixed-bed reactor is used, which is divided into multiple catalyst beds, which is quite connected with multiple reactors in series, and depends on the different temperatures of the inlet and outlet of each bed, and the Different gases are introduced for adjustment, and when the gas is introduced, a certain airflow intensity will be generated, which will generate a certain frequency of vibration at the entrance and exit of the reactor, which will cause damage to the reactor in the long run, and the existing catalyst When the bed is in use, because the active inner surface of the catalyst is not fully utilized, the catalyst cannot be fully reacted, thereby reducing the use efficiency of the catalyst bed. For this reason, we propose a reaction method for the synthesis of n-propanol multi-stage fixed bed reactor
