Fixed-bed hydropyrolysis has been investigated by treating 100 g coal up to 900Β°C and 10 MPa. The devolatilization rate of Beringen coal (32.8 wt% volatile matter) treated on a fixed bed approximates to that obtained by flash hydropyrolysis. However, the oil yield is smaller because of the slower he
