Abstract

Dust and tar-containing gas and vapour 14 produced in the low temperature carbonisation of a finely granular material such as coal or oil shale is fractionally condensed in a first cooling stage 7 to produce a dust- laden tar 15 which is recycled to the carboniser 1 and a tar 18 of low dust content is recovered from a downstream electrostatic precipitator or washer 9. The carbonisation is carried out (e.g. at 500-600 DEG C) by contacting the material with a hot circulating granular heat carrier 20 in a mixing screw 1; coarse dust is removed from the vapour streams 13a and 13b in a cyclone 6 to leave the stream 14 which can be scrubbed and cooled to 150-240 DEG C by spraying with recirculated tar in the first cooling stage 7. <IMAGE>
