Abstract

Coke with good mechanical properties is produced from coal of poor coking quality by (a) agglomerating the finely divided coal at 80-100 degrees C with a binder selected from heavy oils, tars and other high-boiling hydrocarbons to form pellets contg. 5-30 (pref. 20-25) wt.% binder, and (b) coking the pellets by standard methods, esp. in by-product ovens. The uncoked pellets can be stored and transported without breaking, and can be coked by conventional methods to produce lump coke with better cohesion and abrasion resistance than coke produced from the coal alone. Short coking times can be employed. Agglutination of the pellets during coking can be prevented by means of spacer layers (thickness 0.2-2, pref. 0.5 mm) of a finely divided material such as haematite, lime (which also acts as a desulphurizer) or coke dust. Instead of the coal/binder pellets other coal/oil agglomerates, e.g. coal briquettes with an oil binder, can be used. During coking, the heating can be accelerated by blowing hot gas (pref. coke oven gas) through the voids between the pellets from openings in the bottom part of the oven. The oil or tar recovered as byproduct can be recycled as binder, pref. after adding a cracking catalyst (e.g. AlCl3 or bentonite).
