A method for the delivery of a catalyst to a polymerization reactor is disclosed, comprising: contacting a catalyst with a carrier fluid comprising an inert hydrocarbon in gaseous form, the inert hydrocarbon having a normal boiling point of about −1° C. to about 81° C.; and flowing the carrier fluid to the polymerization reactor such that the carrier fluid transports the catalyst to the polymerization reactor. A catalyst delivery system is disclosed, comprising: a catalyst vessel for containing a catalyst; a catalyst injection line for delivering the catalyst to a polymerization reactor, the catalyst injection line being in fluid communication with the catalyst vessel and the polymerization reactor; and a carrier fluid line in fluid communication with the catalyst injection line for delivering a carrier fluid comprising an inert hydrocarbon to the catalyst injection line, the inert hydrocarbon having a normal boiling point of about −1° C. to about 81° C.
A method for the delivery of a catalyst to a polymerization reactor, comprising

The method of any preceding claim, wherein the inert hydrocarbon comprises isopentane.
The method of any preceding claim, wherein the inert hydrocarbon comprises a saturated C5 or a saturated C6 hydrocarbon.
The method of any preceding claim, wherein the carrier fluid further comprises nitrogen.
The method of any preceding claim, wherein the carrier fluid comprises an inert hydrocarbon in gaseous form, liquid form, or a combination thereof.
The method of any preceding claim, wherein the inert hydrocarbon in gaseous form at least partially condenses as the carrier fluid flows to the polymerization reactor.
The method of any preceding claim, further comprising heating a fluid comprising an inert liquid hydrocarbon in a heat exchanger to vaporize the liquid hydrocarbon and form the inert hydrocarbon in gaseous form present in the carrier fluid.
The method of any preceding claim, further comprising heating a catalyst injection line, wherein the carrier fluid flows to the reactor in the catalyst injection line.
