Liaoyang Petrochemical Benzene Production Catalyst Applied Successfully

Recently, the high-efficiency benzene production catalyst with independent intellectual property rights developed by Liaoyang Petrochemical Company was fed into a 480,000-ton/year disproportionation unit, realizing the first industrial application of this catalyst in a domestic unit

"The application of this catalyst not only improves the efficiency of chemical products, but also is of great significance for developing new aromatics production technology, changing the structure of traditional aromatics products, and deeply developing the downstream industrial chain of benzene,

It is understood that traditional aromatics production takes p-xylene (PX) as the target product

To this end, Liaoyang Petrochemical established a special research group to overcome the difficulty of uniform dispersion of active components in the catalyst amplification process, and achieved high conversion of raw materials and high selectivity of benzene in products through innovative catalyst preparation methods

Cheng Guangjian said that the target product of traditional catalysts is xylene, and benzene is used as a by-product; while the main target product of high-efficiency benzene production catalysts is benzene, which improves the selectivity of benzene
