Abstract

Når en blanding av uttjente elektriske apparatbatterier behandles ved pyrolyse, dannes en pyrolyseslagg som for det meste oppviser et restinnhold av kvikksølv på fra 50 til 1500 ppm alt e f ter batteritype. Det synes ikke å være mulig å fjerne dette restinnhold ved å endre fremgangsmåteparameterne for denne eneste pyrolysefremgangsmåte. Ved hjelp av en annen termisk behandling mellom 500°C og 700°C kan imidlertid restinn- holdet senkes til under 10 ppm. Materi- alet som skal behandles, blir fortrinns- vis størrelsesredusert mellom den første pyrolyse og den annen termiske behandling, og den annen termiske behandling utføres under luftgjennomstrømning eller nitrogen- g j«>nnomstrømning.When a mixture of worn-out electrical appliance batteries is treated by pyrolysis, a pyrolysis slag is formed which exhibits mostly a residual mercury content of from 50 to 1500 ppm each of the type of battery. It does not appear to be possible to remove this residual content by changing the process parameters for this only pyrolysis method. However, by means of another thermal treatment between 500 ° C and 700 ° C, the residual content can be lowered to below 10 ppm. The material to be treated is preferably reduced in size between the first pyrolysis and the second thermal treatment, and the second thermal treatment is carried out under air flow or nitrogen flow.
