Embodiment 1

[0026] Such as figure 1 As shown, the embodiment of the present application provides a catalytic condition optimization method for synthesizing acrylic acid, wherein the method is applied to a catalytic condition optimization system, and the method includes:

[0027] S100: Obtain first characteristic information according to the basic information of the first catalyst, wherein the first characteristic information is used to characterize attribute information of the first catalyst;

[0028] Specifically, take the most common industrial acrylic acid production method: the two-step oxidation of propylene as an example. The first stage of the reaction is mainly to synthesize acrolein through propylene. The catalysts currently used are mainly Mo-Bi catalysts, and then Fe, Co, Ni, Mn, Mg and other multiple metal elements are used as additives for catalysis. The second-stage reaction is mainly to synthesize acrylic acid through acrolein. The catalysts currently used are mainly Mo-V ca...

Embodiment approach 1

[0047] Embodiment 1: replace the original code with a new code for the first coding result corresponding to the first selection result;

Embodiment approach 2

[0048] Embodiment 2: Adjust the coding order of the first coding result corresponding to the first selection result; obtain the first modification result after modification. The first and second implementations can be implemented at the same time or only one of them can be implemented. When the first encoding result that has been screened out is the same, it will be screened out again.

[0049] The first programming instruction includes the first random addition and deletion instruction, and the first encoding result in the first selection result can be adjusted in the following two ways through the first random addition and deletion instruction:

[0050] Embodiment 1: The first encoding result in the first selection result can be added or deleted through the first random addition and deletion instruction;

[0051] Embodiment 2: The first coding result in the first selection result can be added and deleted through the first random addition and deletion instruction; the second ...

Abstract

The invention provides a catalytic condition optimization method and system for synthesizing acrylic acid. The method comprises the steps of obtaining first feature information according to basic information of a first catalyst; obtaining first phenotype information according to the catalysis result of the first catalyst, wherein the first phenotype information and the first feature information have a first mapping relation; encoding the first feature information to obtain a first encoding result; constructing a first fitness scoring model, and inputting the first coding result into the first fitness scoring model to obtain a first scoring result; and constructing a first selection model, inputting the first scoring result into the first selection model to obtain a first selection result, and if a first preset feature threshold value is met, preparing a first catalyst according to the first feature information corresponding to the first selection result. The technical problems that when acrylic acid is produced, selection of a catalyst needs to be verified through a large number of experiments, and then the selection efficiency is too low, and the stability is not high in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field related to intelligent manufacturing, in particular to a catalytic condition optimization method and system for synthesizing acrylic acid. Background technique [0002] As one of the important fine chemical raw materials, acrylic acid is widely used in coatings, building materials, adhesives, textiles, leather, papermaking, oil recovery and water treatment and other fields. The consumption of acrylic acid and its esters in my country has grown rapidly, which has accelerated the rapid development of the domestic acrylic acid industry. [0003] With the increase of demand for acrylic acid, the preparation process is also constantly developing. The selection of catalyst has a great influence on the yield and purity of acrylic acid. The selection of catalyst can optimize the catalytic conditions and improve the production efficiency of acrylic acid. [0004] However, in the process of realizing the technical so...
