Problems solved by technology

Due to the poor mass transfer effect, the diffusion problem in the constant gravity field has become the main factor hindering the smooth progress of the catalytic reaction.
In practical applications, the catalytic reaction under normal gravity field generally has the following disadvantages: 1. The amount of catalyst is large, and the utilization rate of the catalyst is low; 2. The mass transfer is slow; 3. The residence time of the material is long, the by-products are many, and the production efficiency is low; 4. , large energy consumption; 5, catalytic reaction equipment volume is large
For example, the application of the rotating bed supergravity field device in the catalytic reaction has not yet been published.

Description

technical field [0001] The invention relates to a method for catalyzing a reaction, in particular to a method for carrying out a catalyzing reaction in a supergravity field. Background technique [0002] Catalytic reactions are widely used in chemical industry, petrochemical industry, biochemical industry and environmental engineering. Almost all catalytic reactions have the problem of internal and external diffusion, such as the diffusion between the reaction materials, the diffusion between the reaction materials and the catalyst, the diffusion between the product and the catalyst, etc. Due to the poor mass transfer effect, the diffusion problem in the constant gravity field has become the main factor hindering the smooth progress of the catalytic reaction. In practical applications, the catalytic reaction under normal gravity field generally has the following disadvantages: 1. The amount of catalyst is large, and the utilization rate of the catalyst is low; 2. The mass t...
