Method for predicating catalytic reforming product

Abstract

The invention discloses a method for predicating a catalytic reforming product. The method comprises the steps of acquiring all components of a catalytic reforming raw material and a content which corresponds with each component; establishing reaction rules based on the types of modular structures of all components in the catalytic reforming raw material; generating a reaction network according tothe plurality of reaction rules and all the components of the catalytic reforming raw materials, wherein the reaction network comprises a plurality of nodes and a plurality of directional sides, thenode represents the component of the catalytic reforming raw material, an intermediate product or a final product, and the directional side represents the reaction path between two members in the catalytic reforming raw material, the intermediate product and the final product; setting the reaction conversion rate which corresponds with each reaction path and the reaction depth of the catalytic reforming raw material in a reactor, and establishing a catalytic reforming product predicating model based on the reaction network, all components of the catalytic reforming reactant and the content which corresponds with each component; and based on the catalytic reforming product predicating model, acquiring all the components of the catalytic reforming product and the predicated content which corresponds with each component.

Description

technical field [0001] The invention relates to the technical field of catalytic reforming, in particular to a method for predicting catalytic reforming products. Background technique [0002] In the process of petroleum processing, catalytic reforming is one of the main secondary processing procedures. It refers to the conversion of light gasoline fraction obtained by distillation of crude oil into aromatic-rich high-octane gasoline (reformed gasoline) under the action of a catalyst. ), and by-product liquefied petroleum gas and hydrogen process. Among them, in order to realize the optimization of the production plan, it is necessary to provide a prediction method of catalytic reforming products to improve economic benefits. [0003] Currently, lumped reaction kinetic models, such as thirteen lumped kinetic models, seventeen lumped kinetic models, and twenty-eight lumped kinetic models, are usually established to predict the composition of catalytic reforming products. Am...

AI Technical Summary

Problems solved by technology

[0005] The content of catalytic reforming products predicted by the above method can only be predicted in aggregate as a unit of the total catalytic reforming product content, but cannot be predicted one by one for each catalytic reforming product content, which is not conducive to production Program optimization
