焙烧

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.

The calcination of the catalysts at high temperature may easily result in theformation of tetrahedral structure Mo species before sulfidation,and decrease theamount of octahedral coordination Mo species.The sinter and loss of the activecomponents would take place during the calcination at overhigh temperature. Meanwhile,the active component could react with support,thus made the activecomponents entered into support bulk phase.

7催化剂在硫化前进行高温焙烧，容易形成四面体结构的钼物种，而八面体配位钼物种减少，且过高的焙烧温度易使活性组分发生烧结，同时可能发生活性组分的流失或与载体发生反应进入载体体相。
