Swirling fluidized-bed reactors for olefin polymerization
View Patent ↗A method for polymerizing olefins in a fluidized-bed reactor is provided. The method involves introducing a fluid into the fluidized-bed reactor at an angle and amount sufficient to induce one or more swirls in the fluidized bed in the reactor.
1. A method for polymerizing olefins in a fluidized-bed reactor, comprising:
introducing a fluid into the fluidized-bed reactor at an angle and amount sufficient to induce one or more swirls in the fluidized bed in the reactor,
wherein the fluid is introduced through a distributor plate at the bottom of the reactor;
wherein the distributor plate comprises perforations, deflectors, or nozzles which introduce the fluid at an angle other than vertical; and
wherein the perforations deflectors, or nozzles are arranged in more than one non-concentric circle to induce multiple swirls within the bed.
2. The method according to claim 1 , wherein the fluid comprises a gas.
3. The method according to claim 2 , wherein the gas comprises olefins.
4. The method according to claim 1 , wherein the fluid comprises a liquid.
