The high-efficiency benzene production catalyst with independent intellectual property rights developed by Liaoyang Petrochemical was successfully fed into the 480,000-ton/year disproportionation unit, and the unit was running smoothly. The first industrial application of a domestic device.
The traditional aromatics production takes p-xylene as the target product. At present, the domestic production of p-xylene is overcapacity, and the profit space of enterprises is constantly being squeezed. Liaoyang Petrochemical adheres to market orientation, puts forward the idea of ??using benzene as the main product of aromatic hydrocarbons, and actively researches high-efficiency benzene production technology. Liaoyang Petrochemical established a special research group to overcome the difficulty of uniform dispersion of active components in the catalyst amplification process. On the basis of completing the amplification research of high-efficiency benzene production catalysts and realizing the production of ton-level products, it actively carried out device adaptability transformation and process simulation; carefully prepared catalysts The operation manual and the catalyst application start-up plan have successfully realized the high-efficiency benzene production technology feeding and start-up. At present, the catalyst is running smoothly, and the main indicators are constantly being adjusted.
The successful application of this catalyst not only greatly enhances the efficiency-creating ability of Liaoyang Petrochemical's chemical products, but also is of great significance for developing new aromatics production technology, changing the structure of traditional aromatics products, and further developing the downstream industrial chain of benzene.
