    Abstract
  • The influence of density of ZnCl2 separation liquid, used for maceral separation, to Tmax of Rock Eval pyrolysis was studied in this research. High volatile bituminous coal samples were collected from Yufeng Mine in Sanhsia, North Taiwan. The coal samples were crushed and then immersed in ZnCl2 solution with five different density of 1.12-1.28g/cm3. Half of the immersed samples were dried after thorough water washing, another half of the immersed samples were dried without washing. All of the samples were run by Rock Eval pyrolysis afterwards. The results indicate that Tmax decreases with increasing density of ZnCl2 solution for unwashed samples. On the other hand, Tmax is rather stable for wased samples. It seems ZnCl2 solution has somekind of catalytic effect on Tmax, although Tmax is still the most stable parameter in pyrolysis.
