Disclosed is a method of preparing a petroleum-alternative bio fuel material such as 5-hydroxymethyl-2-furfural (HMF), 5-alkoxymethyl-2-furfural, levulinic acid alkil ester, etc. through a single process without saccharification, using a catalyst conversion reaction, from galactan that can be massively supplied at low costs and extracted from macroalgae of marine reusable resources.
Thus, the macroalgae of the marine biomass resources is used so that a carbon source can be more easily extracted than that of a lignocellulosic biomass resource without a problem of having an effect on grain price like a crop-based biomass.

Disclosed are: a novel catalyst for the hydrolysis of cellulose, which does not require the use of a large quantity of sulfuric acid for the preparation thereof and from which sulfuric acid cannot be eluted; a novel catalyst for the hydrolysis of cellulose, which is not changed in structure even in hot water and therefore does not undergo the deterioration in activity; and a process for producing a cellulose hydrolysate, mainly including glucose, using any one of the aforementioned catalysts. Specifically disclosed are: a catalyst for the hydrolysis of cellulose, which comprises a porous carbon material having a specific surface area of 800 to 2500 m2/g inclusive and a phenolic hydroxy group content of 100 to 700 mmol/kg inclusive, such as a porous carbon material having such a structure that carbon is filled in pores of mesoporous silica that is used as a template; and a catalyst for the hydrolysis of cellulose or hemicellulose, which comprises the aforementioned porous carbon material and a transition metal belonging to Group 8 to Group 11 and supported on the porous carbon material.
