Furfural is one of the main raw materials in the organic synthesis chemical industry. Its use is very wide, can manufacture rubber, plastic, synthetic fiber, pesticide, medicine, paint, chemical reagents and various additives. In addition, furfural production of waste can be used as fertilizer, to improve the saline soil and improve soil fertility has a good effect. Production of furfural raw materials sufficient. These raw materials are mainly agricultural and sideline products such as oatmeal, corn cob, cottonseed skin, rice husk, peanut shells, buckwheat shells, corn stalks and wheat straw.

The corn cob is crushed by pulverizer and then added to the reactor. The concentration of 3-10% dilute sulfuric acid is added. The ratio of corncob and sulfuric acid is about 1: 0.03. The mixture is fed into high pressure steam at a reaction temperature of 140 to 230℃,pressure of 0.3 ~ 1.0MPa for 5-8h, and then steam distillation of the resulting furfural, condensed into the stripping tower, stripping the bottom of the waste tower, the top of the tower to get rich in furfural water vapor mixture. The mixture is condensed and fed to an oil-water separator. The upper tank contains about 8% of the furfural, into the demethanate tower, by removing the methanol and other low boiling point reaction by-product after the stripping tower. The lower tank contains about 6% of the water, into the neutralization tower, with saturated pure alkali solution and then into the dehydration tower. The water distilled from the top of the column is condensed and returned to the oil-water separator, and the bottom product is subjected to a rectification to obtain furfural products.
