Question: What is the principle and purpose of aromatic isomerization? Answer: Aromatic isomerization is a reaction in which, under certain temperatures and pressures, in the presence of hydrogen and a catalyst, compounds with low levels of p-xylene are converted
Taking C8 as an example, in industry, the isomerization of C8 aromatics involves using C8 aromatics that contain little or no p-xylene as raw material; through the action of a catalyst, these are converted into C8 aromatics at a concentration close to the equilibrium level, thereby increasing the production of p-xylene
Change from straight-chain to branched-chain structure to increase octane rating
Aromatic isomerization is the process in which, under certain temperatures and pressures, in a hydrogen-rich environment and with the action of a catalyst, materials containing low levels of p-xylene are transformed

A catalytic isomerization process that converts mixed xylene into a equilibrium mixture of the four isomers of xylene, under certain temperature and pressure conditions, in the presence of hydrogen and a catalyst. The purpose is to increase the p-xylene concentration

Aromatic isomerization involves using mixed xylene as a raw material; through the action of catalysts, the molecular structure of the components in this mixture is altered, thereby converting the raw material components into p-xylene to the greatest extent possible. Subsequent oxidation and purification steps are then used to produce purified terephthalic acid (PTA), thereby improving the efficiency of resource utilization. Using aromatic hydrocarbons as raw materials, they are converted into aromatic hydrocarbons at a concentration close to the equilibrium level through the action of catalysts, thereby achieving an increase in the production of p-xylene.
