propylene. Although polyolefins can be produced via different production
methods, the gas-phase polymerization process based on fluidized
bed reactor technology is the most important method for the production
of polyethylene since the 1980’s and also polypropylene is increasingly
produced via the gas-phase polymerization process. Although fluidized
bed reactors have been employed for several decades in the chemical
industry, quantitative information on solids motion and macroscopic
circulation patterns is still incomplete.详细>
