以API为13°、粘度为6100 cSt、温度为37.8°的重质原油为研究对象，在泥相间歇反应器中，研究了不同催化剂在低严酷条件下的加氢裂化效果。所评价的催化剂是来自墨西哥不同矿区的钼和铁分析级氧化物和矿石（辉钼矿、赤铁矿和磁铁矿）。在活性金属（Mo或Fe）含量为0 ~ 13 333ppm范围内，研究了催化剂浓度对重油提质的影响。结果表明，要获得适合运输性能（API重力bbb16，粘度在37.8℃< 250 cSt）的升级原油，催化剂的最低浓度为5000 ppm。在评价的操作条件下，没有观察到结焦，对气体的选择性很低。Mo的加氢能力优于Fe，这主要表现在Mo增加了轻馏分组成，减少了重质真空汽油和真空渣油的含量。根据浓度、类型和活动……
A heavy crude oil of 13° API and a viscosity of 6100 cSt at 37.8 °C was used to study the effect of different hydrocracking catalysts at low severity conditions in a slurry-phase batch reactor. The evaluated catalysts were Mo and Fe analytic grade oxides and ores (molybdenite, hematite, and magnetite) from different Mexican mine sites. The effect of the concentration of catalysts on heavy oil upgrading was studied in the range of 0–13 333 ppm of active metal (Mo or Fe). The results showed that the required minimum concentration of catalyst to obtain upgraded crude oil with suitable properties for transportation (API gravity > 16 and viscosity at 37.8 °C < 250 cSt) is 5000 ppm. At the evaluated operating conditions, coke formation is not observed and the selectivity toward gases is low. Mo showed better hydrogenation capacity than Fe, which is observed by an increase in the light fraction composition and reduction of the heavy vacuum gasoil and vacuum residue. Depending on the concentration, type, and acti...
