Sinochem News News Recently, the Petrochemical Research Institute's "Project No. 1" chemical feedstock-based hydrocracking catalyst in 2018 has achieved phased results for the first time. It is a sign that the reformed hydrocracking unit was successfully started up.

The operation results show that the bromine value, sulfur and nitrogen content of the heavy naphtha fully meet the requirements of the reforming feed and the agreed indicators, all products are qualified, and the aromatic potential reaches more than 45%.

In response to the technical needs of enterprises to produce heavy naphtha in the largest amount, researchers have overcome the technical difficulties of the synergistic effect between the hydrogenation function of the catalyst and the suitable acidity, and solved the technical difficulties of producing monocyclic cyclic hydrocarbons with high selectivity of polycyclic aromatic hydrocarbon macromolecules. , to achieve the goal of producing high aromatic latent heavy naphtha in the largest amount, and developed a chemical feedstock type hydrocracking catalyst.

The catalyst has high reactivity, good process operation flexibility, high yield of heavy naphtha, and can also produce 3# jet fuel.

In order to speed up the application and promotion of independent hydrocracking technology in refining and chemical transformation and upgrading, the Petrochemical Institute has completed catalyst production, quality monitoring and performance evaluation in strict accordance with the upper limit of quality. The start-up processes such as switching and process adjustment are carefully arranged to provide technical support for the successful start-up of the device.
