| titleOfInvention | Process for producing ethylene polymer using multiple reactors arranged in series |
| abstract | The present invention relates to a process for the preparation of an ethylene polymer using a plurality of reactors arranged in series, comprising the following steps:n n n a) introducing ethylene, diluent, catalyst, cocatalyst and optionally comonomer and hydrogen into the first reactor,n n n b) polymerization of ethylene and optionally comonomers is carried out in the reaction mixture of the first reactor to produce an ethylene polymer,n n n c) withdrawing the reaction mixture from the first reactor,n n n d) introducing the reaction mixture and fresh ethylene and optionally comonomers and hydrogen into a continuous reactor to prepare additional ethylene polymers,n n n e) withdrawing the reaction mixture from the continuous reactor and, if there is an additional continuous reactor, introduce it with fresh ethylene and optionally comonomer and hydrogen to prepare further ethylene polymer, and the last reactor of the continuous reactors Repeat steps c) and d),n n n f) withdrawing the reaction mixture from the last reactor of the subsequent reactors and recovering the ethylene polymer,n n n At this time, an additional cocatalyst is injected into at least the next reactor of said successive reactors.n n n The advantage of the process of the invention is primarily the reduction in the consumption of catalysts for the production of identical polyethylenes, ie the increase in production capacity. In the most preferred embodiment the process of the invention is carried out in two loop reactors under slurry conditions.n n n Ethylene Polymer, Continuous Array Reactor, Slurry, Metallocene Catalyst |
