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.

It is characterized in that: it uses furfuryl alcohol as raw material, via catalyst to polymerize the poly-furfuryl alcohol to be plated on porous support to form a coat; than drying can carbonizing to prepare compound carbon film.

其特征在于以是以糠醇為原料，在催化劑的作用下聚合成聚糠醇后直接在多孔支撐體上涂覆成膜，經(jīng)干燥久久免费A级毛片高清在钱、炭化制備出復(fù)合炭膜国产色妇女在线视频。

The fractured surfaces and the structure of the resin binder links, which exist in nitrogen-free high-furfuryl-alcohol resin sand mixture and in high-nitrogen content low-furfuryl-alcohol resin sand mixture respectively are investigated by the aid of scanning electronic microscope.
