UPGRADING OF SUGAR-CANE BAGASSE BY THERMAL-PROCESSES .7. CATALYTIC LIQUEFACTION IN MONOETHANOLAMINE (MEA) AND PRELIMINARY FRACTIONATION OF THE OBTAINED PRODUCTS

The liquefaction of sugar cane bagasse in monoethanolamine (MEA) in th e presence of catalysts (zeolite A, non-zeolitic aluminosilicate and z inc chloride) as well as in the absence of catalysts is described in t his paper. The influence of the catalysts on the yield of the generate d products is verified through a fractionation method based on relativ e solubility parameters. The influence of the catalysts on the convers ion yield was also verified. The catalysts that yields the greater qua ntity of oils is the non-zeolitic aluminosilicate. However, in the ove rall conversion process of sugar cane bagasse, the most efficient cata lyst was found to be zeolite A.
