    • This application is related to a process for hydrocracking of heavy naphtha feeds. An improvement in the selectivity of the hydrocracking process was observed by decoupling aromatics saturation and hydrocracking reactions. This benefit has been observed for hydrocracking with either noble metal or base metal catalysts. The improved selectivity was observed in a low pressure as well as standard pressure operation. A decrease in the amount of light gas (C1-C4) and an increase in the amount of liquid product produced was observed. Decoupling the aromatic saturation and hydrocracking reactions also resulted in a significant improvement in process operability (i.e., decreased runaway tendency) and controllability and a reduction in catalyst deactivation rate.
    • 本申请涉及重质石脑油原料加氢裂化工艺。 通过解离芳烃饱和度和加氢裂化反应观察到加氢裂化过程的选择性的改善。 已经观察到用贵金属或贱金属催化剂进行加氢裂化的这个益处。 在低压以及标准压力操作中观察到改进的选择性。 观察到轻质气体(C1-C4)的量减少和产生的液体产物量的增加。 芳族饱和和加氢裂化反应的去偶合也导致了工艺操作性(即失控趋势减少)和可控性的显着改善以及催化剂失活速率的降低。

    • A process for catalytic multi-stage hydrogenation of heavy hydrocarbonaceous feedstocks using catalytic ebullated bed reactors, operated at generally the same reaction conditions. In the process, the feedstock is reacted with hydrogen in a first stage catalytic ebullated bed reactor at operating conditions of 700-850 DEG F temperature, 800-3000 psi hydrogen partial pressure at the reactor outlet, 0.2-2.0 V,/hr/V, liquid hourly space velocity, catalyst space velocity of 0.03-0.33 bbl/day per pound of fresh catalyst and at reduced superficial gas velocity of 0.02-0.3 ft/sec in each reactor, so as to provide increased percentage liquid volume and reduced gas hold-up in each reactor. The first stage reactor effluent liquid portion is fed into the second stage reactor. The second stage reactor effluent is phase separated and fractionated to produce lower boiling liquid products. A vacuum bottoms fraction normally boiling above about 650 DEG F and preferably above 900 DEG F is recycled back to the first stage reactor.
