Release of HCl during temperature programmed pyrolysis at 10℃/min of a bituminous coal and anthracite has been studied with an on line analyzer. The profiles for the rate of HCl formation depend strongly on coal type, showing the main peak at 470℃ with the former coal and the sharp and shoulder ones at 300-350℃ with the latter sample. Both coals provide high conversions (90-100%) to HCl up to 800℃. The sharp peak at 300℃ almost disappear after NH_3 washing. The rate profiles are slightly changed in the range of 2.5-10℃/min. It is suggested that Cl functionality is one of the key factors to determine HCl formation.
