The calcine were leached by sulfuric acid when the temperature was 30℃, and the leaching ratio of molybdenum and manganese could reach 99% and 92% respectively.

结果表明，将辉钼矿(MoS_2)和二氧化锰(MnO_2)按摩尔比1：3的比例混合均匀，在管式炉中依次在温度为450℃和550℃下分别焙烧2小时，鼓风量为15-20ml/min，此条件下MoS_2的分解率可达99.5%以上，固硫率可以达92%。

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。

By exploring the production of caustic calcined dolomite in traditionalscorch limekiln, improvement project and related technique are analyzed, as well as theperformance of caustic calcined dolomite in converter protection by slag splashing.

通过对老式焦烧石灰窑转产轻烧白云石的探索，研究制定了焦烧窑转产轻烧白云石对窑炉的改造方案和生产工艺，探讨了轻烧白云石在转炉中溅渣护炉的使用效果。

Solid additives such as potassium carbonate and calcium carbonate would not have the same problems above, and also increasing the content of soluble silicon.

研究表明：将催化剂C_3及配比为5∶1～8∶1黑液与粉煤灰均匀混合后，先在电阻炉上进行干燥，然后在750～800℃马弗炉中煅烧10min即可制得有效硅含量≥30%的硅肥。

Based on the fault tree of the cooling water system in asphalt gas decontaminating for carbon calciner,quantified evaluating system of reliability of cooling water system is set up by using of quantified analysis theory of fault tree.

在建立焙烧炉沥青烟气净化系统中冷却水系统故障树的基础上，运用故障树定量分析理论，建立了冷却水系统可靠性定量评价体系，对该系统发生故障的概率作出判断，从而能够及时、合理地确定冷却水系统的状况，以便及时采取应变措施，保持系统可靠运行

The results showed that the sulfur recovery ratio declined along with the increase of NH3 content.NH3 in acid gas should be burnt up to decompose into N2 and H2O in the burner of acid gas,or it would form crystalline of ammonium salt to obstruct the following equipments,even make production shut down.

结果表明，随着酸性气中氨含量的增加，硫回收率下降；酸性气中的氨必须在制硫燃烧炉中完全燃烧分解为N2和H2O，否则会形成铵盐结晶而堵塞下游设备，严重时将导致停产；根据酸性气中氨含量的不同，可选择不烧氨和烧氨2种工艺流程。

Study is made of a new process for directly extraction of the cobalt oxalate from ammonium oxalate in the acid solution directly dissolved from lithium cobaltate.

研究了从钴酸锂直接溶解后的酸溶液中用草酸铵直接提取草酸钴的新工艺，采用氟盐将酸溶液中的铝完全全络合，然后用草酸铵在pH为2，温度60℃下沉钴，再在马弗炉中煅烧成氧化钴，所得产品可达到Co2O3？

It is discovered that the ignition temperature T1 of the mixtrues to be used to produce briquets is reduced and the successive combustion temperature T2 of the mixtures is increased owing to mixing some inorganic matter with raw coal. The...

据此，试图说明如下现象：在同样的层燃炉中，当原煤挥发分高时，型煤比原煤烧得更好；当原煤挥发分较低，而无机添加物又过多时，型煤不如原煤烧得好，出现接火困难、炉渣中可燃物过高等现象。

The discovery of the several kinds of possibility that introduce B contaminations includes glass ware, deionized water, and convertion of Be 〓 into BeO cooked in muffle furnace etc.

在有效降低样品中B含量的同时，摸索了制备BeO样品中引入B污染的几种可能：玻璃器皿、去离子水、以及在马弗炉中完成Be〓灼烧转化为BeO等。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.
