The commercial application of homemade serous catalyst succeed.

Recently the homemade serous catalyst co-developed by Beijing Chemical Research Institute and Guangzhou Petrochemical Company (GPC) passed the commercial application test on GPC's polyethylene unit, showing that great breakthrough was made in the research and development of homemade serous catalyst.

Compared with the solid catalyst, the serous catalyst enjoyed many priorities such as accurate feeding amount, easily control, high activity, low ash residue, high product quality, low cost and etc. At present, most domestic polyethylene units used the solid catalysts and with the commercial application of the serous catalyst, the cost of polyethylene will reduce RMB 50 -100/t, bringing considerable profit to the polyethylene producers in China.

Beijing Chemical Research Institute developed the first batch of homemade serous catalyst in July 2002 and made the experiment to test the catalysts property. In November 2002, Sinopec Science Department organized the experts to do the experimental appraisal of the catalyst in Beijing.

At the end of 2002, with the application experiences and technical priority in the serous catalyst, GPC did the commercial application experiment on its polyethylene unit when no pilot test was conducted. In this course, many key technical problems were solved, some properties were improved and reactor parameters were optimized, laying a foundation for the further improvement of the serous catalyst.

In August this year, GPC conducted a 10-day application test of the homemade serous catalyst and the production unit worked normally and the products had good quality, which showing that the commercial probation of homemade serous catalyst achieved success.

Now the project is making preparation for the technical conclusion and project appraisal.
