Upgrading of Sugar Cane Bagasse by Thermal Processes. 7. Catalytic Liquefaction in Monoethanolamine (Mea) and Preliminary Fractionation of the Obtained Products

Abstract

The liquefaction of sugar cane bagasse in monoethanolamine (MEA) in the presence of catalysts (zeolite A, non-zeolitic aluminosilicate and zinc chloride) as well as in the absence of catalysts is described in this paper. The influence of the catalysts on the yield of the generated products is verified through a fractionation method based on relative solubility parameters. The influence of the catalysts on the conversion yield was also verified. The catalysts that yields the greater quantity of oils is the non-zeolitic aluminosilicate. However, in the overall conversion process of sugar cane bagasse, the most efficient catalyst was found to be zeolite A. 963
