- W1574459564 abstract "The role of exchangeable cations in the release of carboxylic functional groups and tars from a Montana lignite has been studied. Pyrolysis was carried out in an entrained flow reactor using a dilute stream of coal particles, and high heating and cooling rates. Direct determination of the carboxylic functional groups on the coal and char samples by ion exchange with barium acetate was employed to study both the amount and kinetics of decarboxylation. These results indicate that the presence of metal cations decreases the extent of decarboxylation at temperatures of 973, 1073 and 1173 K when compared with the behaviour of an acid washed lignite. It was also possible to determine first order activation energy values using this direct measure of decarboxylation. The activation energies determined for decarboxylation were 100 and 97 kJ mol−1 for the raw and acid washed samples, respectively. Furthermore, it is reported that the presence of metal cations on the coal resulted in a decrease of tar release of 70–94%. Analysis of the tars by Fourier transform infrared spectroscopy indicated that the tars released during pyrolysis were more aliphatic when metal cations were present." @default.
