## Abstract A fly ash sample was used as sorbent for trace element (As, Se, Cd and Zn) species at high temperatures in flue gases from coal gasification. The influence of temperature (550 and 750 °C) and gas composition (with and without H~2~S and HCl) on retention capacity was evaluated. It was co

Coal liquefaction residue characteristics were discussed. The heavy organic matter content and the ash content affect the viscosity of residue. A simplified kinetic model was developed that could estimate the heavy organic matter content of residue at some liquefaction conditions and its ash content
