SECTIONS This Step has the following sections: SECTION FUNCTION CATALYST MUD Oil, grease and Catalyst powder are blended to achieve the desired PREPARATION concentration and form a catalyst slurry or mud.CATALYST The Catalyst blend is charged into cylinders. Pistons force the INJECTION catalyst mud from the cylinders into the precontacting pot to mix with the Donor and Teal before going to the prepolymerization reactor.HYDRAULIC OIL Hydraulic oil is pumped to the top of the metering cylinders, METERING forcing the Catalyst mud from the bottom of the cylinders to the precontacting pot.
