    Through graphical investigation of Soviet coal and Chinese coal, the follow-ing important conclusions are obtained. (1) The inadequacy of old coal classification methods is discussed and anentirely new method of coal classification with volatile matter on combustiblebasis as abssicca and the coal characteristic coefficient β=2.35((H~P-0.126O~P+0.04N~P)/(C~P+0.375S_?~Pas ordinate is proposed, The graphical charts show perfectly satisfactory withthe different kinds of coal located in perfectly distinct areas of classification.Thus the detailed classification which the old methods fail to give out, is perfectlypossible with the new method. (2) The ultimate composition of coal on combustible basis, like C~2, 0~2, H~2,N~2 and the analytical moisture, W~a and their variation with the volatile matteron combustible basis and with each other is graphically investigated and it isfound that their variation with each other proceeded with distinct regularitywith the exception of sulphur and ash, so that their composition percentage canbe approximatety estimated with rough accuracy through these graphs and theclose check of analytical results of ultimate composition can be carried outthrough the use of these graphs. (3) a general relationship in the proximate and ultimate composition of the pure coal substance on combustible basis for typical Chinese coals can bederived with the following straight line formula for the average percentage of car-ben on combustible basis in terms of the volatile matter on combustible basisin the region of bituminous coal: C~2=93.3-(V~2/4.55) during (8fuel industry and power indus-try in operation and design work of power plants. The monographs for the coalcombustion calculations will be shown in another paper for the practical use forpower plant operation, because of too many graphs in one paper. Owing to the fact that the only data available for the ultimate analysis ofChinese coal is from the Northeast region and North China region, the degreeof accuracy of these graphs for Chinese coal is limited by the available data,although the comparison with the graphs for Soviet coals show a perfect simi-larity so that it can be concluded these graphs can be used for the Chinesecoals in other regions. Critical opinions are welcomed by the author to improve this paper.

    Some kinds of Chinese coal have been hydrogenated in the autoclave for catalyst studies.Under the condition:temperature 450°,initial hydrogen pres- sure 100 atm./20°,and reaction time 1 hr.,the conversion of Shenli coal of Fushun reaches or exceeds 95%,when SnC_2O_4+NH_4Cl,SnCl_2,tin ore+NH_4Cl, ZnCl_2,(NH_4)_2MoO_4,FeS,or sulfurized bogiron ore is used as catalyst. A time-saving“microautoclave”technique is developed and is recommended for the preliminary study of coal hydrogenation. In the range of temperature 400—450℃ and initial hydrogen pressure 50—100 arm.,the order of hydrogenation activity of the three series of catalysts studied is:tin>molybdenum>iron;for the conversion of asphaltene,the activity of tinhalide catalyst is also the highest. As shown in this investigation,the Shenli coal of Fushun is well amenable to hydrogenation,and its use in the production of aromatic compounds and liquid fuel is very prospective.

    以不同煤种在高压釜内进行了加氢催化剂的选择试验.在450°、100大气压/20°(H_2,初压)、恒温1小时的条件下,用 SnC_2O_4+NH_4Cl,SnCl_2,锡矿+NH_4Cl,ZnCl_2,钼酸铵,FeS,废无机脱硫剂或黄土(加硫)等作为催化剂,抚顺胜利煤的转化率可达到或超过95%.在试验过程中还建立了效率较高的小管试验,可用来代替普通大管作煤加氢的初步评价工作.以小管试验为基础,改变操作条件,在400—450°与50—100大气压初氢压的范围内,锡系催化剂适应能力最强,钼次之,铁最差.对沥青质的加氢转化来讲,锡的活性也是最高的.

    An apparatus using fluidized partial-oxidation technique is described for distilling various bituminous coal fines, ranging from the noncaking Fushun coal up to the highly agglomerating and expanding Lou-ping coal. The operations have proved successful and satisfactory. The results have shown that in the presence of due amount of steam in the air stream and stirring device in the reactor, agglomerating coals can be handled in this apparatus and the tar yields ef bituminous coals may be as high as over 100% of...

    An apparatus using fluidized partial-oxidation technique is described for distilling various bituminous coal fines, ranging from the noncaking Fushun coal up to the highly agglomerating and expanding Lou-ping coal. The operations have proved successful and satisfactory. The results have shown that in the presence of due amount of steam in the air stream and stirring device in the reactor, agglomerating coals can be handled in this apparatus and the tar yields ef bituminous coals may be as high as over 100% of that of the Fischer assay. Coke particles thereby obtained from the low-temperature carbonization are easily breakable and have higher activity than ordinary semicoke fines. This would serve as a technical basis for the complex utilization of boiler fine fuels.

    低溫干餾是煤綜合利用的重要途徑之一,与火力發电相結合的粉煤低溫干餾是切待解决的問題。在实验装置上研究用飽和空气为热載体,以流化床單反应器处理粘結性粉煤,获得了一定的結果,認为装置比較簡單,操作容易,收油率与处理强度也較高。現正进行处理能力为10吨/日的半工业試驗。
