The caking index of 11 bituminous coals of different ranks with various inert contents was determined. The nonlinear correlation between caking index and inert content was confirmed. The physical meaning of each item in the regressing equation G=A-B×f(I) were discussed. The function f(I) is a ratio of total inert meteral to active component. The constant A is approximately equal to 110 or 20.The coefficient B represents the rate of varying caking capability of active component with increasing inert content....

The caking index of 11 bituminous coals of different ranks with various inert contents was determined. The nonlinear correlation between caking index and inert content was confirmed. The physical meaning of each item in the regressing equation G=A-B×f(I) were discussed. The function f(I) is a ratio of total inert meteral to active component. The constant A is approximately equal to 110 or 20.The coefficient B represents the rate of varying caking capability of active component with increasing inert content. In addition, both the caking index of pure active component(Go) and critical inert content can be regard as indications of caking property of active component. The relation between Go and the reflectance of vitrinite indicates the dependance of caking capability of active component on the coalification bituminous coal.

通过测定11种不同变质程度的烟煤在改变惰性物含量下的粘结指数,确认了粘结指数与惰性物含量呈曲线变化的规律,分析了曲线的回归式G=A-Bf(I)中各项的物理意义。函数f(I)是总惰性物与活性组分含量之比,常数A≈110,或≈20;系数B反映了活性组分粘结能力随惰性物增加而变化的快慢。另外,纯活性组分的粘结指数G_0与临界惰性物含量均可作为活性组分粘结性的指标,而G_0同镜质组反射率的关系则反映了随煤化度不同的煤中活性组分粘结能力的变化。

The Raman spectra of sulfidized state W/γ-Al_2O_3 catalyst at different sulfida- tion conditions were obtained by in situ Laser Raman spectroscopy. The rela- tionship between the chemical state and sulfidation condition of selected typ- ical tungsten compounds was studied. It is concluded that the AMT was sul- fidized more easily than the tungstate. The free WO_3 was very hard to be sul- fidized. The tungsten catalyst can be used as hydrodesulfurization or hydrodenitro- genation for petroleum processing and coal liquifation. The Raman technique has a high sensitivity for studying the composition and structure of the tung- sten catalyst. In order to better understand the ultimate transformation of the oxidized state into the sulfidized state, this paper applied the controlled- atmosphere and high temperature in situ Laser Raman spectroscopy in combi- nation with Auger spectroscopy and FSCA to study the chemical state of active phase for sulfidized and oxidized state. For the oxidized state there are two specific compounds; polytungstate and the free WO_3. For the sulfidized state two specific compounds identified were oxysulfur-tungstate and WS_2. The WS_2 phase is transformed from the polytungstate, which can serve as the active phase for HDN catalyst.

用原位激光喇曼光谱测得了硫化态W/y-AI_2O_3催化剂在不同条件下的喇曼光谱.选择了一些典型的钨化合物,研究了它们的硫化条件和化学形态之间的关系,发现AMT最容易硫化,H_2WO_4处于中等,而WO_3最难硫化。本文应用控制气氛高温原位激光喇曼光谱,配合以俄歇能谱及ESCA能谱研究了氧化态和硫化态催化剂上活性组分的化学形态.在氧化态催化剂表面上发现了两种化合物:聚钨酸和聚集态WO_3。在硫化态催化剂表面上也发现了两类化合物:WS_2和硫氧化钨以及非活性组分的WO_3。而WS_2则是从聚钨酸转变而来,是催化剂加氢脱氯(HDN)的主要活性物.

Technical analysis,ultimate analysis,petrological constitution deter- mination,Roga Index,Audibert-Arnudilitation value and loss of weight on heating of the coal from Zhangzhuang,Shandong and that from Mine No.9,Pingdingshan,Henan are investigated,with the purpose of comparing their cohesiveness.Centering around their Roga Indices,adiscussion is made on their active components,vitrain content and stable content to identify their dissimilarities in cohesiveness.A conclusion is made that in coals labelled ‘gas coal’from both origins,the one produced in Mine No.9 Pingdingshan has a better coking property,whereas gas coal from Zhangzhuang contains a higher percentage of active components which justifies a better cohesiveness. The experimental findings are worth consultation for WISC to use gas coal from Henan in place of that from Shandong.

本文介绍对山东张庄煤和河南平顶山九矿煤所进行的对比实验研究——工业分析,元素分析,测定岩相组成、罗加指数、奥亚膨胀度及热失重;重点用罗加指数讨论了两矿煤的活性组分,镜质组、稳定组的粘结性差异,得出了同属气煤牌号的平九煤的质量优于张庄煤的结论。但由于活性组分含量是张庄煤高于平九煤,故张庄煤的粘结性比平九煤好。实验对武钢用河南气煤代替山东气煤有参考价值。
