Experimental estimation of possibilities of suspension technology of polypropylene production with application of different generations of ziegler-natta catalysts

On the basis of R&D results on laboratory and pilot levels the possibility of production and expansion of “Tomskneftekhim” Ltd. brand assortment of polyolefin plastics with the use of contemporary titaniummagnesium catalysts (TMC) is analyzed. The production results of “Tomskneftekhim” Ltd. polypropylene output, reached due to the use of catalyst systems of I (aluminothermal TiCl3) and II (MSK-TiCl3) generations, and forecasting results for system of IV generation (TMC) are presented in the report. The experimental testing of propylene polymerization kinetic features, raw material quality, and influence of catalyst system composition and conditions of formation on exploitation characteristics of TMC was carried out by the example of two trade marks of TMC. The conclusion was drawn that the realization by “Tomskneftekhim” Ltd. of a complex program of R&D activities for implementation of the IV generation catalyst system in the suspension technology of the polypropylene production will increase the competitiveness of the process.
