摘要：An Indonesian oil sand were studied by hot water extraction and fixed bed pyrolysis for bitumen recovery. It was found that the concentration of alkali and temperature both had effects on the yield of water extraction. But the maximum yield was only 12.74wt% under the investigated condition due to its oil-wet structure. As to pyrolysis in fixed bed reactor, the influence of holding time, flow rate of gas carrier and temperature on the tar yield were considered. The maximum tar yield was 17.01wt% under 140mL/min of gas carrier, 480  C, 0.1MPa and holding for 40min. The results show that pyrolysis is more suitable for bitumen recovery of the oil sand compared with hot water extraction. ? (2014) Trans Tech Publications, Switzerland.
