To investigate the possibility of direct production of smokeless fuel, a moderate temperature coking was applied. Coals used for this purpose are named as No. 800 in International Classification and cause considerable amounts of smoke emissions due to their high tar contents, when burned. Following a preheating treatment at 120{degree}C, the smokeless fuels (semicokes) were produced by coking of the samples 16-32 mm at 450{degree}C, with a heating rate of 150{degree}C/h. These semicokes have been found to be strong, their tar contents are far below 2%, and volatile matters are mainly composed of CH{sub 4} and H{sub 2}. The formation of semicoke particles smaller than 10 mm at the level of 25 to 30%, could not be avoided. Briquetts prepared by using these particles and tar or molasses as binder, were also found suitable for heating purposes. 8 refs., 1 fig., 4 tabs.
