This article presents the results of a study on the process of direct catalytic liquefaction of sugar cane bagasse, using ethanol as solvent. A systematic study with 12 different types of commercially available catalysts was accomplished. For each catalyst, the conversion yield of sugar cane bagasse into liquefied products, which are useful as liquid fuels and chemical feedstocks, was determined. The highest conver sion yield was observed when a nickel catalyst on SiO2-Al2 O3 was used. The liquefied products were fractionated into oils, asphaltenes, and asphaltols. The oil samples were separated and then fractionated into eight different chemical classes by preparative liquid chromatography. The highest proportion of light-oils (F1 to F5) was obtained with the potassium fluoride catalyst on silica gel. High proportions of resins (F6) were obtained with three types of catalysts: nickel on SiO2-Al2 O3 , ruthenium, or platinum on activated carbon powder. The highest proportion of asphaltenes (F7) and of asphaltols (F8) were obtained with the niobium oxide catalyst. |
