New catalyst industrial application succeeded

Domestic carbon four/carbon five full hydrogenation catalysts can successfully replace imported catalysts. On August 3, the news from the China Petroleum and Petrochemical Research Institute revealed that the LY-2005 catalyst for carbon 4 and carbon 5 hydrogenation developed by the institute was used for industrial applications on Shanghai Petrochemical's mixed carbon 4 and carbon 5 plants. This is the catalyst that was once again successfully used in industrial plants after its first application at Lanzhou Petrochemical. The operation results of the device prove that the performance indicators of the catalyst can completely replace the foreign catalysts of the same kind and have made beneficial attempts for the technological progress of similar domestically produced catalysts.

With the refinement of domestic ethylene pyrolysis and production of C4 and C5 fractions, in the current domestic C4 and C5 available technologies, the full H2 utilization pathway is considered to improve C4 and C5 utilization. The best technical route.

In order to make full use of the C4 resources, in 2004, Lanzhou Petrochemical began to build a carbon tetrahydrogenation plant to produce maleic anhydride, but in the hydrogenation reactor design process, there are no mature catalysts to choose from. In the face of the high cost of using foreign catalysts, Lanzhou Petrochemical commissioned the Lanzhou Center of Petrochemical Institute to develop catalysts.

Researchers from the Lanzhou Central Chemical Catalyst Research Institute set up a special focus group to solve the technical needs of China's oil refining and chemical companies. Starting from analysing the nature of raw materials, the project team has boldly broken through the preparation methods of traditional supported hydrogenation catalysts by analyzing the nature of raw materials, completed laboratory development, amplification, and industrial production of catalysts, and has been using industrial applications in Lanzhou Petrochemical. to date.

At the end of 2010, Shanghai Petrochemical learned that the catalyst was used for technical exchanges with the Petrochemical Institute after the application of the Lanzhou Petrochemical industrial device. The Lanzhou Center of Petrochemical Institute completed the catalyst production task for the nature of carbon tetra-carbon and carbon five mixed raw materials of Shanghai Petrochemical, the requirements for hydrogenation products, and the technological conditions of the equipment. The LY-2005 catalyst produced by them fully meets the requirements of the Shanghai Petrochemical industrial production equipment and opens up new space for the use of catalysts for the blending of carbon tetra and carbon five hydrogens.
