Abstract:
1. Regenerator for treatment of an offgas comprising haloorganosilicon compounds, the offgas being heated by means of a heat storage material in the form of a bed and an outlet for the heat storage material being present in the regenerator, this outlet being connected to a separation apparatus for removal of adhering oxidized silicon-containing material and the separation apparatus being connected to an inlet which allows the heat storage material to be fed back to the regenerator, wherein the regenerator is provided with an internal multilayer coating which comprises, in the sequence from the inside of the regenerator outward, a) a first layer of a ceramic material comprising aluminium oxide (Al b) a second layer of a further ceramic material comprising aluminium oxide (Al c) a third layer comprising foamed, amorphous silicon oxide (SiO d) optionally a fourth layer comprising a vinyl ester resin with woven glass fabric and/or woven carbon fabric.
