FremgangsmÕte for termisk krakking av avfallspolymerer |
摘要 |
This invention relates to a process for thermally cracking waste polymer(s) comprising chlorinated polymers in a reactor in the presence of a fluidizing gas and a fluidized bed of solid, particulate fluidizable material at a temperature from 350-600 DEG C to cracked products comprising a mixed vapour of lower hydrocarbons which have a chlorine content of less than 50 ppm. In the process, the cracked products emerging from the fluidized bed are passed through one or more guard beds comprising calcium oxide or a compound capable of giving rise to calcium oxide under the reaction conditions maintained at a temperature in the range from 400-600 DEG C. in such a way that the chlorine content of the product is less than 50 ppm. <IMAGE> |
