Aiming at the existing problems such as high toxicity, severe corrosion and pollution of dilute sulfuric acid as catalyst for furfural preparation in present industry, this study attempted to prepare furfural via hydrolysis of corncob using acid salt as catalyst. The effects of catalysts type, reaction temperature, reaction time on furfural yield were investigated through single factor experiments. The optimum hydrolysis technology parameters for producing furfural were obtained as follows:hydrolysis time of 90 min, hydrolysis temperature of 190℃ and sodium hydrogen sulfate as catalyst,. Under this condition, the furfural yield reached 39.91%.
