Gas condensate through the identification of chromium catalysts

Recently, the Guangzhou Petrochemical, Shanghai Chemical Research Institute, Shanghai Co., Ltd. jointly undertaken profits catalyst suitable for industrial gas condensing chromium catalysts applied research projects, through Sinopec Corporation's technical appraisal.
The project is jointly developed by SLH-211 catalyst is a proprietary, suitable for condensing gas phase fluidized bed process to produce a new type of chromium-based catalyst polyethylene products. In Guangzhou Petrochemical 200,000 tons / year polyethylene unit of industrial application tests showed that the catalyst can be stable in condensing mode operation is obtained grades of polyethylene products meet the required specifications.
With conventional titanium catalyst, chromium-based catalyst prepared polyethylene resin containing a small amount of long chain branching fractions and ultra-high Molybdenum tube weight component, its processing performance is more excellent, expanding the scope of application of polyethylene products. The catalyst helps to increase the application of polyethylene grades, improve performance, expand production capacity, to enrich the range of products of polyethylene, high density polyethylene to promote domestic development and other complete sets of technology has important significance.
The successful application of the project to achieve two major breakthroughs: First, the first in the country to achieve the titanium catalyst chromium catalyst online hot switching; two in the domestic gas phase fluidized bed process for the first time the use of domestic chromium catalysts entering from non-condensing high load-condensing smooth operation, to fill technology gaps in this area, creating a new record of similar devices.
