Atmospheric and high pressure TPR profiles were obtained from initial and LiAlH{sub 4} treated coal samples: Illinois No 6, Wyodak-Anderson, Upper-Freeport, Gedling, Goynuk, Kimmeridge, Dorset-Cuddle, Rasa and Mequinenza. AP-TPR results indicated that LiAlH{sub 4} treatment not only removes pyrite, but also changes, removes and/or modified other sulphur functionalities. The different AP-TPR profiles are discussed in detail and assignments of the signals are based on previous model compound work. Both AP-TPR and HP-TPR results on the same sets of samples are compared with literature results obtained with other S-characterisation techniques.
