LICUEFACCIóN CATALíTICA DIRECTA DE CARBONES. EFECTO DE LA TEMPERATURA

a high volatile bituminous coal from the department of cundinamarca (colombia), was liquefied in the presence of a polymetallic catalyst in a 500 ml batch reactor at 370, 410 and 450 °c under hydrogen atmosphere, using tetralin as hydrogen donor solvent and residence time of 1 h. when the catalyst was used and the temperature increased, the coal conversion and the oil yield increased too. the maximum oil yield obtained was 67% at 450 °c.
