  hydrotreating
It is a promising support for cracking and hydrotreating catalysts.
      
The mechanism of thiophene hydrodesulfurization over sulfide catalysts for hydrotreating and the effect of the catalyst composition and feed on the number, distribution, and performance of active sites were studied using 35S and 3H isotopes.
      
Based on the results of radioisotopic study, a method for systematic testing-monitoring of sulfide Co(Ni)Mo catalysts for hydrotreating is developed.
      
The hydrotreating activity of the catalysts was proportional to the amount of hydrogen consumed in the range 20-500°C during TPR.

The changes of composition of the hydrogen-processed lubricating oils expo-sed to ultraviolet light were studied with respect to exposure time.Samples ofhydrotreated and hydrofinished neutral oils from the Renqiu crude were usedin this study and sediments thus formed were analyzed.The results showthat S and N containing sediments are mostly formed during the initialstage of exposure,Oxidation products,i.e.compounds containing hydroxyl,carbonyl,and carobxyl groups constitute the main body of the sediments.Itis...

研究了在紫外光照过程中任丘减四线加氢处理润滑油及加氢补充精制润滑油组成的变化,并对生成的沉淀进行了分析。结果指出,硫氮化合物集中在光照初期出现的沉淀中。沉淀为含有羟基、羰基、羧基等含氧基团的氧化产物。加氢油出现沉淀的原因与芳烃结构有关,多环,短侧链芳烃是沉淀的主要来源。

By coprocessing at mild thermal conditions, the petroleum residues were upgraded and the coal was partially liquefied to yield valuable liquid and gaseous products. The petroleum residues were upgraded due to demetalation,conversion to distillates and viscosity reduction. The liquid product could be used as a heavy fuel or hydrotreating and cracking feed. The demetalation reactions involve thermal breakdown of asphaltenic and metal-containing compounds of the residue,and the coal to reactive radicals, which...

By coprocessing at mild thermal conditions, the petroleum residues were upgraded and the coal was partially liquefied to yield valuable liquid and gaseous products. The petroleum residues were upgraded due to demetalation,conversion to distillates and viscosity reduction. The liquid product could be used as a heavy fuel or hydrotreating and cracking feed. The demetalation reactions involve thermal breakdown of asphaltenic and metal-containing compounds of the residue,and the coal to reactive radicals, which in turn, react with each other to form insoluble products on the unconverted coal for removal. Coal reactivity towards demetalation decreases with coal rank: bituminous>sub-bituminous>lignite. All residues were demetalated to a comparable degree at similar conditions. Thus, this approach to demetalation is especially useful for high metals-containing petroleum derived residues.

通过缓和热条件下联合加工,可提高石油渣油质量和使煤部分液化来生产有价值的液体和气体产品.石油渣油由于脱金属而转化成馏分油并降低粘度而提高质量。该液体产品可用作重燃料油或加氢处理和裂化的原料。脱金属反应包括渣油中的沥青质和含金属化合物的热裂解,以及煤产生活性基团,继而它们互相反应,并在未转化的煤上形成不溶解的产物而除去。煤的脱金属活性随煤的等级下降而降低,其顺序为:烟煤>次烟煤>褐煤。各种渣油在类似的条件下可脱金属到相接近的程度.因此,这个方法对高金属含量渣油的脱金属尤其有用。

A high liquid-yield delayed coking process operating under a combinedrecycle ratio [(fresh feed + recycle)/fresh feed] equal to 1 is proposed based onthe investigation of the effect of recycle on the liquid product distribution.Pilot plant results indicate that its liquid yield is 5-8% higher than the con-ventional coking process. This process is particularly suitable to refinerieswith insufficient coking capacity and excess cracking capacity. It can be rea-dily adopted by existing coking units with only minor...

A high liquid-yield delayed coking process operating under a combinedrecycle ratio [(fresh feed + recycle)/fresh feed] equal to 1 is proposed based onthe investigation of the effect of recycle on the liquid product distribution.Pilot plant results indicate that its liquid yield is 5-8% higher than the con-ventional coking process. This process is particularly suitable to refinerieswith insufficient coking capacity and excess cracking capacity. It can be rea-dily adopted by existing coking units with only minor changes. The merits ofhydrotreating of the coker heavy gas oil to be used as FCC feedstock are di-scussed and stressed.

本文在考察循环比对延迟焦化产品收率的影响的基础上,提出了一种联合循环比[(新鲜进料+循环油)/新鲜进料]为1的高液收焦化工艺。中型试验结果表明,其液体收率比常规焦化工艺高5—8%。这一工艺特别适用于焦化能力不足而裂化能力有富余的炼油厂。现有焦化装置只需做很少改动就可按高液收焦化工艺操作。文中还重点讨论了焦化蜡油经加氢处理后作为催化裂化进料的优越之处。
