The present application relates to an olefin polymerization method and system in the field of olefin polymerization. The method combines a supported double catalyst with a series process, introduces a liquid material obtained after heat exchange and gas-liquid separation of a circulation gas flow into a separate first reactor to get into contact with the supported double catalyst for polymerization reaction, and then introduces the reaction material and the first polyolefin generated by reaction into a second reactor to continue polymerization reaction, thereby enabling particles to circulate between first reactor and second reactor, improving mixing effect of two polyolefins with obvious differences in properties, avoiding the occurrence of phase separation, and facilitating the production of polyolefins with excellent performance. At the same time, ethylene gas is introduced into first reactor to further reduce the hydrogen/ethylene ratio, increase the molecular weight of polyethylene and improve the product performance.

Provided is a method for preparing a high-performance ultra-high molecular weight polyethylene resin. An ethylene monomer is subjected to a polymerization reaction by means of a single active site-loaded polyethylene catalyst in a reactor to prepare a polyethylene resin having a lower entanglement degree and a narrower molecular weight distribution. Compared with the prior art, the polyethylene raw material obtained by means of polymerization has the characteristic of a narrow molecular weight distribution, thereby greatly improving the mechanical properties of the resulting ultra-high molecular weight polyethylene; furthermore, the low entanglement property thereof solves the current problem that an ultra-high molecular weight polyethylene with a narrow molecular weight distribution is difficult to uniformly dissolve in a solvent.
