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
