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

本文分析了当前糠醇生产的现状，指出液相法加氢工艺是糠醇生产的主流工艺，铜铬催化剂由于其本身具有良好的性能在糠醇生产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.

将糠醛液相加氢生产糠醇产生的废渣置于真空干燥箱中，在较低的负压状态下保持130℃的温度，蒸馏回收废渣中的有机物，返回糠醇精制车间获得合格的糠醇与糠醛产品；剩余的固体废弃物与纯碱混合，在反射炉中焙烧，浸取获得铬酸钠水溶液；最后剩下的粗氧化铜溶于硝酸得到硝酸铜溶液；将铬酸钠溶液、硝酸铜溶液按一定比例混合，加入氨水搅拌，分离出的沉淀经传统方法焙烧活化、造粒制得新催化剂，回用于糠醛液相加氢生产糠醇。

Two skeleton nickel catalysts A and B were prepared at 50 ℃ and 90 ℃ respectively and hydrogenation of furfuryl alcohol to tetrahydrofurfuryl alcohol was studied with the catalysts under different reaction conditions.

研究了以骨架镍为加氢催化剂，以糠醇为原料制备四氢糠醇。在中温和高温下制备了两种骨架镍催化剂A和B，研究了不同的反应条件对两种骨架镍催化剂的影响，确定了最佳反应条件。

It is found that conversion of furfuryl alcohol was higher than 99%,and THFA yield and selectivity achieved or were close to 97%by using catalyst Ⅱ with a small quantity of promoters.

对于含少量助剂的镍催化剂Ⅱ，在393 K、4.0 MPa和空速0.25 h\+\{-1\}时，糠醇转化率可达99%以上，四氢糠醇收率和选择性都达到或接近97%。

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为原料，在催化剂的作用下聚合成聚糠醇后直接在多孔支撑体上涂覆成膜，经干燥、炭化制备出复合炭膜。

Kebony stops wood from rotting by placing it in a vat containing a substance called furfuryl alcohol, which is made from the waste left over when sugarcane is processed.

Kebony公司首先把木材放入盛有一种被称作糠醇的物质的容器中以防止其腐烂，这种糠醇由甘蔗加工产生的废料生产而成。

The THFA yield and selectivity were 2.0%higher than those by using catalyst Ⅰ without promoter,3.0%higher than those by using Raney nickel catalyst under the same reaction conditions and furfuryl alcohol conversion.

在相同反应条件和糠醇转化率条件下，四氢糠醇收率和选择性均比没有助剂的镍催化剂Ⅰ高2.0%，比骨架镍催化剂高3.0%。

Tetrahydrofurfuryl alcohol was prepared from furfuryl alcohol with hydrogenation reduction by using the catalyst at 393-413 K,0.25-0.4 h-1 and 2.0-4.0 MPa.

在393～413 K、0.25～0.4 h\+\{-1\}、2.0～4.0 MPa条件下，用上述催化剂加氢还原糠醇制备四氢糠醇。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
