摘要	Molten salt hydrates (MSH) are unique in overcoming the characteristic recalcitrance of crystalline cellulose. We show that cellulose can be efficiently hydrolyzed into short-chain oligomers and glucose under mild conditions in concentrated LiBr solution without using any additional acid catalyst. Under optimized reaction conditions, short-chain oligomers with a yield of 90.4% can be obtained. Selective hydrolysis in the MSH is effective even at a high initial cellulose concentration (higher than 10 wt%). The obtained oligomers are solvated and soluble in the MSH. We show that amorphous carbon of a large surface area is effective for adsorption of the short-chain oligomers, cellobiose, and glucose from the MSH. The adsorption capacity and adsorption affinity of the carbon increases by similar to 4 and similar to 15 times in MSH with increasing the oligomer chain length compared to glucose and is negatively influenced by the ion concentration of the MSH. A stepwise hydrolysis process for converting crystalline cellulose into glucose is developed, whereby cellulose is firstly hydrolyzed into soluble short-chain oligomers in the MSH. The oligomers are then separated from the MSH using amorphous carbon and finally hydrolyzed into glucose under mild reaction conditions.
