AbstractWe report a novel lignosulfonate-based heterogeneous sulfonic acid catalyst (LF) which offered high yields of monosaccharides (75-98%) in hydrolysis of polysaccharides, such as cellobiose, maltose, D-melezitose, sucrose, inulin, and starch. Specific activity in cellobiose hydrolysis was 5.6 +/- 0.3 mol glucose per mol -SO3H. Kinetic analysis showed that the apparent activation energy of cellobiose hydrolysis over the LF catalyst is 98.5 kJ mol(-1), which was less than 110-138 kJ mol(-1) for mineral acids, organic acid homogeneous catalysts or grafted sulfonic acids. The catalyst was recycled by filtration and reused four times in cellobiose hydrolysis without apparent loss of catalytic activity. NMR characterization suggests that the better accessibility of cellobiose to -SO3H sites and multiple bindings of hydroxyls of cellobiose on -COOH and -OH sites may account for its superior performance. This is a new method of utilizing pulp industry waste as sulfonic acid precursor; otherwise sulfonation process is required for preparing heterogeneous sulfonic acid catalysts. (c) 2013 Elsevier B.V.
