Yangzi Petrochemical completed the first industrial application of metallocene polyethylene catalyst

Recently, Yangzi Petrochemical and Beijing Chemical Industry Research Institute cooperated to realize the first industrial application of metallocene polyethylene (PE) catalyst developed by its own technology, producing high-performance metallocene polyethylene products, providing a reliable technical guarantee for industrial production.

.

Under the unified arrangement and strong support of the Science and Technology Department of the group company, since 2020, Yangzi Petrochemical has cooperated with the Beijing Research Institute of Chemical Industry to develop metallocene polyethylene catalysts
.
On the basis of a large amount of work in the early stage, the key research personnel have formulated an adaptive transformation plan for the existing catalyst preparation test device (SPC test device) of Yangzi Petrochemical, and invested in the transformation
.
In October 2021, the adaptive transformation of the SPC test device was completed
.
In order to ensure the smooth start-up of the test unit, Yangzi Petrochemical established a start-up team, combed it one by one according to the requirements for the start-up conditions of the industrial unit, and compiled a series of documents such as the start-up plan, parking plan, and emergency plan, and implemented the relevant safety management requirements
.
In November 2021, the plant was successfully put into operation, and three batches of catalyst preparations were completed, achieving stable batch preparation
.

In order to ensure the smooth industrial application of the catalyst, Yangzi Petrochemical makes full use of the integrated synergy mechanism for the production, sales, research and application of new polyolefin products, implements the project leader and overall responsibility system, strengthens departmental coordination, and promotes the effective implementation of various tasks
.
Through continuous pilot-scale polymerization tests, they completed mass production of metallocene pipe products
.
The analysis shows that the product has wide distribution characteristics and excellent processing performance
.
Based on the pilot test results, they formulated an industrial trial production plan for metallocene catalysts, and recently realized the successful application of self-made metallocene catalysts in No.
2 polyethylene unit.
The industrial production process was stable and controllable, and various indicators reached the level of imported catalysts.
, output more than 80 tons of qualified metallocene pipe products
.

The successful development and industrial application of metallocene polyethylene catalysts has strongly promoted the process of localization of metallocene polyethylene catalysts, optimized the catalyst synthesis process, improved the preparation conditions, implemented the industrial production of catalysts, industrial applications of catalysts, and developed high-end metallocene polyethylene catalysts.
The whole chain of vinyl products and other products has laid a solid foundation
