Abstract
Direct coal liquefaction is the direct conversion process of a solid coal into a liquid under high pressure and temperature. Under this condition, hydrogen and catalyst must be added to obtain the fuel and to improve the efficiency of the process. Experimentally, direct liquefaction of brown coal was carried out on 1 liter autoclave with limonite catalyst and heavy oil as a solvent. The operating condition was 450oC and 12 MPa, residence time of 0-60 minutes. Detailed investigation of the flow pattern in the reactor is very important for the process optimization. This study presents two-dimensional transient hydrodynamic and reaction modeling of Brown Coal Liquefaction (BCL) reactor using CFD. The model demonstrated the capability of commercial CFD code fluent 6.3 to describe the flow pattern in the reactor. The model predicted the distribution of yield, temperature, and velocity vector in the reactor.
