The research involves destructive distillation of Maiganga coal, analysis of the yields and characterization of condensable products. Maiganga coal was distillated in a pyrolyser, the condensable products were recovered in a three stage separator, and the products were collected over a range of temperatures. The yields’ of the char was obtained by measuring the weight of the char and then divided by the starting weight of the coal sample. The condensable products yields were obtained in similar manner as the char. The yield of the gaseous product was obtained by subtracting the sum of yields of char and condensable products from unity. The yields of semi-coke, water and tar were 63, 11, and 7%, respectively. The tar obtained was characterize using GC/MS to determine the chemical composition. The characterization was carried out using Agilent Gas Chromatography/ Mass Selective Detector (GC/MSD). The GC/MSD results show that the dominant compounds in the tar are aromatic, acid, and esters. However sulphur, nitrogen, chlorine, and fluorine compounds were present. The specific dominant compound is Benzeneacetic acid, 4-tetradecyl ester, (C22H36O2) about 33%, and the least were 1H-Thiopine, 2,3,6,7-tetrahydro-4,5-didehydro-3,3,6,6-tetramethyl (C10H16OS), 1-oxide, 4-(2,5-Dihydro-3-methoxyphenyl)butylamine (C11H19NO) about 6%. The coal may serve as feedstock for production of coke and aromatic compounds.
