After analysing the condition of furfural alcohol production, the paper points out that the main

本文分析了當前糠醇生產的現狀亚洲一区二区三区无码国产，指出液相法加氫工藝是糠醇生產的主流工藝，銅鉻催化劑由于其本身具有良好的性能在糠醇生產中仍然占有重要地位

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.
