PURPOSE:To obtain oil and gas for fuel, etc. from oil sand, etc., by introducing fine powder of solid raw material containing hydrocarbon together with heated fine powder in a rotary drum having oxygen-free atmosphere and containing coarse solid granules, and carbonizing the raw material while rotating the drum. CONSTITUTION:Preheated powdery raw material 12 obtained by preheating the powder of solid raw material 1 containing hydrocarbon and having a particle diameter of about <=10mm. in a preheater 2 is introduced together with fine powder for thermal medium 13 heated at a high temperture by the cyclone combustor 5 into the rotary drum 3 (mixer retort) having oxygen-free atmosphere and containing a proper amount of solid granules having larger diameter than the raw material powder and the thermal medium powder, from one end of the drum 3. The inside of the drum 3 is maintained at the optimum temperature for carbonization, and the raw material is carbonized under agitation by rotating the drum. The carbonized product is discharged from the other end of the drum through a metal mesh 16, etc., and separated into the oil and gas 4 obtained by the carbonization and the carbonized fine powder mixture 19 partly containing the residual carbon.
