1. "Aromatic complex

1.1 Context

Aromatics are a family of hydrocarbons found in crude oils, and are particularly important in the world of petrochemicals. In particular, they form the basis for the manufacture of many modern synthetic materials. The most sought-after aromatic intermediates are benzene, toluene and paraxylene (BTX) (figure 1 ). These compounds must meet the petrochemical industry's demand for aromatic raw materials. Aromatic hydrocarbons are obtained mainly by catalytic reforming or steam cracking processes, which produce an "aromatic gasoline". However, when the latter is obtained in proportions that are not adapted to demand, it is necessary to carry out additional transformations. This is...
