        Ground coal is uniformly moistened with 2% aqueous Ca acetate, mixed with Fe filings and Na₂CO₃ and distilled in a continuous horizontal retort.  A tar containing phenois 0.9, aromatic compounds 73, saturated hydrocarbons 18, and unsaturated hydrocarbons 8% is obtained, as compared with a normal tar containing 40.2, 43.0, 11.0, and 5.8%, respectively.
