In order to investigate the effect of operating variabls on the yield of aromatics,a certain fraction of a straight run gasoline containing 48.4% (wt.)naphthenes was catalytically converted into aromatics over a bed of 100 ml 14—20 mesh,granular,platforming catalyst under various opera- ting conditions.The ranges of these investigations were:temperature 430— 510℃,pressure 20—50 atm.,WHSV 1.58—6.32 and hydrogen-oil molar ratio 4:1—10:1.The single pass fresh hydrogen process was adopted. The result...

In order to investigate the effect of operating variabls on the yield of aromatics,a certain fraction of a straight run gasoline containing 48.4% (wt.)naphthenes was catalytically converted into aromatics over a bed of 100 ml 14—20 mesh,granular,platforming catalyst under various opera- ting conditions.The ranges of these investigations were:temperature 430— 510℃,pressure 20—50 atm.,WHSV 1.58—6.32 and hydrogen-oil molar ratio 4:1—10:1.The single pass fresh hydrogen process was adopted. The result of data treatment implied that the following second-order reaction rate expression correlates the aromatics production rate r with the operating variables satisfactorily. r=r_0(1-bx)~2, where x=aromatics yield based on feed(wt.%),and r_0 and b are constants. Superfacially r_0 may be regarded as the reaction rate constant,whereas b as a stochiometric coefficient of the equivalent kinetic equation.Both are functions of the operating temperature,pressure and hydrogen-oil molar ratio. For 4:1 hydrogen-oil molar ratio,which seems to be one of the most promising operating conditions,the differential and integral forms of the rate equation for aromatics yield are as follows: The apparent activation energy of the aromatics yield reaction by platforming under the conditions investigated,therefore,equals to 33,500 cal/gm-mol.The values of b at isobaric conditions may be correlated as: In b_(50)=8200/RT-17.5/R The significance of b is discussed thermodynamically. Considerable variations,though not large,in aromatic yield were observed when the hydrogen-oil molar ratio changed from 4:1 to 10:1.For example,at 30 atm.,490℃,this effect may be expressed by r=(p/186p+144)×10~5(1-bx)~2, where p=partial pressure of the feed stock,atm. Besides,the relative initial rates of C_8 aromatics,toluene and benzene formation were found to be in the increasing order of their molecular weights.Thus under certain operating conditions the initial rate of C~8 aromatics formation was 2.5 times that of the toluene initial formation rate,and 20 times that of the benzene formation rate.

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.

Straight-run naphthas of Yumen, Kramayi, Central Szechuan (60-130℃), and Fushuan hydrogenated shale oil (60-120℃) were platformed separately for aromatics in an isothermal reactorcontaining 80 ml. catalyst. The catalyst used in this study was developed at the Research Institute of Petroleum Science, Ministry of Petroleum Industry. Data are presented to show platforming conditions, material balance and product distributions. Aromatic yields on weight basis were 38.5% (Yumen), 31.8% (Kramayi), 46.6% (Central Szechuan) and 32.2% (Fushun) respectively. Byproduct hydrogen yield was 1.7-2.2% (weight basis), liquid yield was 90-94% (weight basis). During 2170 hours catalyst life test, the aromatic yield decreased from 38.8% to 35.4% 80-180℃ straight-run Yumen and Kramayi gasolines for octane improvement were preliminarily investigated. At a yield of 90% (weight basis), debutanized reformed gasoline had a clear octane number of 72 (motor method). The octane number of the feed stock was 44 (motor method).
