Abstract: To solve the bottlenecks in the basic research of polyethylene technology, China National Petroleum Corporation has constructed creation platform for polyethylene pilot technology. The key facility is 50kg/h gas phase full density polyethylene pilot plant, which can be used to produce polyethylene products in a full range of density by means of titanium, chromium and metallocene and other catalysts. The catalyst feeding system is creatively designed for the plant that adopts eight items of dedicated technology including a catalyst powder trace precise feeding technology. A technological committee was established in operation and management of this creation platform to test the “process and safety integration” management pattern and long-term cooperative and exchange mechanism. As an important integral part of CNPC’s oil refining technological creation system, the platform accelerated development process of the key projects and conversion of independent research results and played an active role in improvement of polyethylene production technology. Up to now, a total of 11 research projects have been brought under study, providing support for seven projects in their industrial application. Appraisal of eight catalysts in four categories of Z-N, metallocene, chromium and titanium-chromium composites was completed at the same time. A total of 15 new products have been developed, such as special material for auto fuel tank, creating more than 50 million yuan of economic results.
