Lignocellulosic biomass is increasingly and widely perceived as a renewable resource rather than an organic solid waste today, as it could be converted into different kinds of chemicals [1]. The conversion of glucose to value-added chemicals is considered to bridging the petrol chemical industry and biorefinery, since cellulose, being one of the major component of lignocellulose, could be converted to glucose via hydrolysis. However, the glucose conversion system is very complex, and many possible parallel reaction pathways co-exist [2-7]. Thus, the control of different reaction pathways in the reaction network is paramountly important for obtaining target product with high selectivity. This presentation will analyse the complex system and discuss some examples for obtaining high selectivity to HMF and related compounds. 1. The complexity of the structure of glucose and its isomerization under reaction conditions, the complexity of products, the complexity of the catalyst used. 2. Controlling of the reaction pathways via catalytic alteration with the synergetic effects of promoters. 3. Controling of the reaction pathways via solvent effects and process alternation. 4. Concluding remarks and prospectives.
