Abstract: The present disclosure relates to fluid bed processes that utilize silica particles as a fluidization aid. The process comprises reacting one or more reactants in a reactor comprising a fluid bed to form a product. The fluid bed comprises a catalyst composition comprising a catalyst and an inert additive composition comprising silica particles from 0.5 wt % to 30 wt %, based on the total weight of the catalyst composition. The silica particles are discrete, inert particles that are mixed with the catalyst in the fluid bed.

Abstract: The present disclosure relates to a process for preparing polymers using a plug flow reactor. The process includes providing an aqueous monomer solution comprising amide monomers; evaporating the aqueous monomer solution to form a concentrated monomer solution; and polymerizing the concentrated monomer solution in a plug flow reactor comprising a shell side and a tube side to form a first process fluid comprising polymers. The concentrated monomer solution flows on the shell side from the inlet to the outlet.
