Abstract
A method for reducing fouling in an oligomerizing reactor that includes upgrading C2 to C4 hydrocarbons within the oligomerizing reactor in the presence of a fouling inhibitor having a particle size D50 of less than 100 μm and forming linear alpha olefins and polymer during the oligomerizing, wherein the fouling inhibitor changes the morphology of the polymer.
Claims15
A method for reducing fouling in an oligomerization reactor, comprising:
- oligomerizing C2 to C4 hydrocarbons within the oligomerization reactor in the presence of a fouling inhibitor having a particle size D50 of less than 100 μm;
- and
- forming linear alpha olefins and olefin polymer mixture, wherein the fouling inhibitor changes the size and/or shape of the olefin polymer mixture.
A method for reducing fouling in an oligomerization reactor, comprising:
- oligomerizing ethylene in the oligomerization reactor in the presence of a fouling inhibitor having a particle size D50 of less than 100 μm;
- and
- forming linear alpha olefins and polyethylene during the oligomerization, wherein the fouling inhibitor changes the morphology of the polyethylene.
