A new recovery technology of solid waste was made which is from furfuryl alcohol production by furfural hydrogenization. When the solid waste is placed in a vacuum drying box, and is under lower negative pressure and at 130℃, the organic materials in solid waste can be distilled and then returned to the refining workshop to produce qualified furfuraldehyde and furfuryl alcohol. The remainder is mixed with soda ash and roasted in a reverberating furnace. The sodium chromate can be obtained by leaching. Rough cupric oxide is dissolved in nitric acid and cupric nitrate is obtained. A new catalyst was prepared by the above sodium chromate and cupric nitrate and used in furfuryl alcohol production.
