Recently, good news was received from the intermittent main unit of Polypropylene Plant No. 2 of Daqing Huake Co., Ltd. Polypropylene spherical catalyst developed by the Daqing Chemical Research Center was successfully piloted and a total of 5.62 tons of polypropylene products were produced. All qualified. Polypropylene ball catalysts have long changed depending on the import situation.
Polypropylene catalyst is a key technology for the development of polypropylene products. It had long been dependent on imports. The price of polypropylene catalysts in the international market has remained high. Since 2004, Daqing Chemical Research Center has conducted research and development on the characteristics of polypropylene catalysts, including the carrier preparation process and the design and synthesis of new electron donors. At present, the 5L scale carrier preparation and the 3L scale catalyst preparation scale-up study have been completed. . The experimental results show that the catalyst activity, polymer bulk density and so on all meet the requirements of the index, and a spherical polypropylene catalyst with good performance has been prepared.
The catalyst has the advantages of stable process control, stable release of active polymer, low fines content and high bulk density. Due to the low content of active metal in the catalyst, not only the amount of the activator and the external electron donor is reduced, but also the production cost of the polymer is reduced, and the ash content of the polymer is reduced.
It is understood that the current polypropylene production capacity of PetroChina Group exceeds 1.86 million tons/year, accounting for 34.6% of the total domestic production capacity.
