Polymerization synthesis of semi coke activated carbon
Semi coke SC in fine particles is a byproduct of the coal pyrolysis process Subsequently the sample was dried using a freeze drying oven Equal amounts of the pretreated SC solid and PVA were mixed to make a sol followed by the addition of a small quantity of KOH The resulting mixture was then subjected to freeze drying
Comparison of semi coke with traditional pulverized
semi coke can be used as an alternative fuel for PCI; however when used for sintering alternative fuel matching of the 75 lm using a ball mill heated to 105 C in a drying oven for 2 h then cooled down to room temperature and sealed in a drying box for further application The proxi mate analyses of the samples are listed in Table 1
