A comparative study of the carbonisation of a wide range of coals, wet and after preheating, was carried out. The 6 t coal capacity oven of the INCAR Experimental Coking Test Plant and the 2 t/h preheating pilot plant, Precarbon process, installed by ENSIDESA annexed to the INCAR plant, were used. Influence of the preheating process on coal plastic properties was followed through Arnu dilatation, Gieseler fluidity and swelling index tests. Structural modifications of the coals were examined by FT-IR. Coal samples below 0.15 mm that do not need to be crushed for analysis and Arnu dilatation were chosen. A Koppers-INCAR test of all coals studied was carried out. Cokes obtained were characterised by optical microscopy, SEM and image analysis. Size analysis, coke strength (Micum e Irsid tests), reactivity and post-reaction strength, chemical changes and porosity were also determined.
