The present invention relates to a process for the continuous preparation of a polyolefin from one or more α-olefin monomers in a reactor system, the process for the continuous preparation of polyolefin comprising the steps of: +feeding a polymerization catalyst to a fluidized bed through an inlet for a polymerization catalyst; +feeding the one or more monomers to the reactor, +polymerizing the one or more monomers in the fluidized bed to prepare the polyolefin; +withdrawing polyolefin formed from the reactor through an outlet for polyolefin; +withdrawing fluids from the reactor through an outlet for fluids and transporting the fluids through first connection means, an heat exchanger to cool the fluids to produce a cooled recycle stream, and through second connection means back into the reactor via an inlet for the recycle stream; wherein a thermal run away reducing agent (TRRA) is added to the reactor in a discontinuous way.

Silicon granulate is produced in a fluidized bed reactor having a fluidized bed region fluidized by a gas flow and heated by a heating apparatus. Seed particles and a feed gas including hydrogen and silane and/or halosilane is continuously supplied, and elemental silicon is deposited on the seed particles to form the silicon granulate, which is discharged as a continuous product stream from the reactor. The fluidized bed temperature affects the quality and formation of the product stream, which may be determined as the temperature of an offgas stream from the fluidized bend region. The temperature, as a responding variable may be determined and controlled by means of the mass and energy balance of a defined scheme.

Gas phase polymerization processes include contacting an input stream comprising a monomer and an induced condensing agent in the presence of an inert gas with a catalyst in a fluidized bed reactor to produce a polymer, unreacted monomer, and an output gas; recycling a recycle stream of the unreacted monomer from the reactor to the input stream; venting at least a portion of the output gas from the reactor; and maintaining a partial pressure of the inert gas in the reactor above a reference inert gas pressure to decrease losses of the recycle stream with the vented output gas. The processes may include controlling the inert gas partial pressure to vary the total reactor pressure up to the maximum safe pressure, without causing carry-over of product polymer.

A universal chemical processor (UCP) including a reactor vessel having a central longitudinal axis and main chamber comprises a first inlet port for a main feedstock, a second inlet port for a fluidizing medium and a third inlet port for one or more reactants. The UCP also includes a reactive radioactive chemical processor (R.sup.2CP) that contains a radioactive element positioned extending along the longitudinal axis in the main chamber. In operation, a fluidized bed can be supported in the main chamber when a fluidizing medium and feedstock are supplied to the main chamber through the first and second inlet ports and the radioactive element of the R.sup.2CP emits ionizing radiation that is capable of ionizing feedstock and reactants, inducing chemical reactions, and sterilizing and decomposing any organic materials within a radiation zone.
