FIELD: chemistry.
SUBSTANCE: gas-phase reactor with continuous circulating layer includes lifting section for realising contact of catalyst and first gas composition, which contains olefin, for formation of polyolefin in conditions of fast fluidisation or mode of pneumatic transportation of catalyst, suspended in gas stream. Sinking section serves for realisation of contact of catalyst and second olefin-containing gas composition for formation of additional polyolefin in conditions of fast fluidisation mode or mode of pneumatic transportation of catalyst, suspended in gas flow. Transporting section serves for supply of part of catalyst, polyolefin and additional polyolefin from sinking section to lifting section.
EFFECT: invention provides gas reactor, capable of producing wide range of products without requiring special catalysts or multistage reactors.
