The group types of residues obtained by hydrotreating are determined using high ionizing voltage and low-resolution mass spectrometer (MS) The vaporization conditions of saturates, aromatics and resins in the residues and the repeatability of the method are investigated The asphaltines in the residue samples were precipitated using n-heptane, and the heptane-soluble components were further fractionated into saturates, aromatics and resins on the alumina/silica gel column Then, the fractions were analyzed by a VG AutoSpec MS All glass heated inlet system (AGHIS) was used to vaporize the sample into the gaseous phase The saturates in the sample can be fully vaporized between 320℃ and 380℃, and the temperature ranging from 350℃ to 380℃ is adequate for that of aromatics, while resins are vaporized using temperature program from 150℃ to 380℃ at the rate of 5℃/min with the vaporization yield of 42 5% The analysis results show that the vaporizing temperature has little impact on the composition at certain temperature ranges and the standard deviation of the method is less than 0 6

利用质谱仪低分辨、高离子化电压质谱技术对渣油加氢处理过程族组成变化进行了研究。考察了渣油饱和份、芳香份、胶质的气化条件和方法的重复性。用正庚烷沉淀出渣油中的沥青质 ,脱去沥青质的部分用氧化铝和硅胶的串联吸附色谱柱分离为饱和份、芳香份和胶质。实验中 ,渣油饱和份馏份在 32 0~ 380℃温度范围、芳香份馏份在 35 0~ 380℃温度范围可充分气化 ,且测定结果的重复性较好 ;渣油胶质部分采用 15 0℃进样 ,以 5 0℃ 10min升至 380℃的方式重复性较好 ,胶质的气化率可达 42 5 %。分析结果表明 :在一定的温度范围内族组成基本不随气化温度变化 ,方法标准偏差小于 0 6。分析了两组渣油加氢处理前后的样品为渣油加氢催化剂的研制及工艺研究 ,提供了基础数据。

对工业运转后的各种渣油加氢催化剂进行物理性质的剖析,结果表明:(1)为了更真实地反映不同状态下催化剂孔体积和比表面积的变化情况,孔体积和比表面积应以单位装填体积催化剂的孔体积和单位装填体积催化剂的比表面积表示,即分别以"ml/ml"和"m2/ml"为单位;(2)所用渣油加氢脱氮催化剂在运转中比表面积损失较大,表明其孔径较小,易被固体沉积物堵塞;(3)现有的渣油加氢催化剂在运转中焦炭沉积量较高,故提高此类催化剂的抗结焦性能是开发催化剂必须考虑的关键问题之一。

At same average reaction temperature of catalyst beds in residue hydrotreating unit, the effect of different combination of catalyst bed temperatures on product quality and running cycle was investigated. The result showed that its effect on product quality was small. For maintaining a long running cycle, the reaction temperature of each catalyst bed should not be adjusted voluntarily and the reaction temperature of the hydro-demetallization catalyst bed should be kept at a low limit.

介绍渣油加氢处理装置在催化剂床层平均反应温度相同时,各催化剂床层反应温度的不同组合对产品质量和装置运转周期的影响。试验结果表明,在渣油加氢催化剂的级配装填系统中,催化剂床层平均反应温度相同时各催化剂床层反应温度的不同组合对加氢常压渣油产品性质影响较小。为了保持加氢装置的长周期运转,各催化剂床层反应温度不应随意调整,脱金属催化剂的反应温度应有一低限值。
