[0025] The present invention will be further described below with reference to the drawings and examples.

[0026] Reaction mechanism and kinetic model

[0027] Laboratory research results of the acetylene catalytic hydrogenation reaction process show that hydrocarbons cover the surface of palladium metal to form two different catalytic centers: A center and E center. The A center is composed of a series of narrow adsorption centers, which can adsorb acetylene and hydrogen, but because they are too narrow to adsorb ethylene, ethylene hydrogenation cannot be carried out; the E center can adsorb all reactants including ethylene, due to the steady state The number of E centers on the catalyst is much smaller than the number of A centers. The hydrogenation rate of acetylene on the F center is negligible, and the main hydrogenation reaction is ethylene. A reaction of π-C2H2 hydrogenation to generate ethane will occur on the A center, and this reaction is first hydrogenated by the verti...

Abstract

The invention relates to a method for optimizing process operation of catalytic hydrogenation reaction of acetylene in an industrial device. The method has the following beneficial effects: based on a hydrogenation reactor model, the genetic algorithm is used for fitting the parameters of a dynamic model and a deactivation model so as to achieve the aim of precisely describing the chemical reaction process, and on the basis, the genetic algorithm is reused for optimizing the process operation conditions according to the practical industrial production goal, thus the influence of each factor in an industrial reactor on the reaction process can be described; and the models have higher industrial data fitting and predicting precision and good usability, and in addition, the modeling method is suitable for various catalytic hydrogenation reactions in fixed bed reactors and has wide applicability.
