Definitions
- An essential feature of the invention relates to the arrangement and design of the inlet for the polyolefins in the reaction volume.
- This has to condition the polyolefin for injection into the reaction volume to a heater for heating the polyolefin on the softening temperature, wherein the heating may be formed by the aforementioned Temper michsvorraum.
- a heater for heating the polyolefin on the softening temperature
- the heating may be formed by the aforementioned Temper michsvorraum.
- polyolefin such as polypropylene (softening temperature to 200 0 C, decomposition from about 350 0 C) or polyethylene in the softened conveying and injectable state, ie in a viscosity range in the range between 10 and 70 Pas.
- the polyolefin is preferably input to a conveyor such as a screw conveyor or a melt pump 'as raw batch as granules and heated already in this, that is, outside of the reaction volume into a pumpable mass.
- the device comprises a switchable recycle facility (reflux and refeed) for the polyolefin, ie, a fluidic compound for the aforementioned polyolefin melt between the inlet and the outlet for the polyolefin in the reaction volume.
- the fluidic connection has a delivery pump and / or a heater.
- the inlet comprises at least one nozzle (includes extruder arrangements), which is aligned in the reaction volume in the direction of the de-halogenated substances. Injection of the polyolefins generally takes place by means of nozzles with a preferred large specific surface area into the substances, which advantageously accelerates the chemical processes taking place.
- an inert gas atmosphere such as a nitrogen atmosphere
- the gas supply can be realized either as an additional separate introduction or as a gas supply for a two-component or multi-fluid nozzle for the introduction of the polyolefin or of components of the halogenated substance, the inert gas assuming the function of a carrier gas, for example for atomization.
- One embodiment relates to a reaction system with an overhead introduction of a polyolefin melt, ie with a nozzle assembly at the top of the reaction volume and from there down into the vapor space.
- FIG. 4 shows the concentrations of various bromine compounds 28 (respectively measured signal height profile, ie no specific unit) over the experimental time course 29 with a debromination of 3.5 g tribromophenol (TBP) in a reactor of an embodiment according to FIG. 3 with PP as reaction partner.
- TBP tribromophenol
