Principal aspects of investigations into fluidised carbonisation undertaken at the Marienau Experimental Station

IN 1948, CERCHAR, (the Centre d'Etudes et de
Recherches des Charbonnages de France), started
investigations on the application of fluidisation
to the carbonisation of coal-fines.
Preliminary investigations led to the construction
of a 100 g/hr capacity fluidiser and subsequently a
pilot plant having a capacity of 1 ton/hr was jointly
set up by CERCHAR and IRSID) (Institut de Recherches
de la Siderurgie, de France), at Marienau in the
Lorraine coal fields. The present paper describes the experiments carried out with this pilot plant.
