Abstract: A novel process for metal content reduction of hydrocarbon oil is disclosed, which is primarily aimed at reduction of vanadium and nickel. The process uses electricity to accelerate the demetallation process, but only the flow of electrons of the electric current is used to expedite the reaction, instead of the electrolysis effect of the electric current. The process is carried out by adding inter-phase surface active reagent and phase transfer catalyst at a relatively low temperature range of 80 to 200° C. and achieves metal content reduction for vanadium and nickel. Aqueous phase alcoholic derivatives of amine solution is treated with hydrogen sulfide, carbon dioxide, etc. by additive reaction to render it more suitable for carrying more electric current and make them more active for metal reduction.

Abstract: An integrated process for production of ultra low sulfur products of high octane gasoline, high aromatic naphtha and high Cetane Diesel from high aromatic middle distillate range streams from any cracker units such as Light Cycle Oil (LCO) stream of Fluid catalytic cracking (FCC) units and subjected to hydrotreating for removal of heteroatoms like sulfur and nitrogen. The effluent from hydrotreating is subjected to hydrocracking at same pressure of hydrotreating step above for selective opening of saturated ring of multi-ring aromatics. The effluent from hydrocracking is separated in CUT-1, CUT 2 in which the monoaromatics and alkylated monoaromatics are concentrated and CUT-3 in which concentration of saturates significantly increased. The CUT-3 is selectively oxidized in selective oxidation step in presence of catalyst, an oxidizing agent and operating conditions such that it results in diesel product with more enhanced Cetane.

Abstract translation: 公开了一种用于烃油的金属含量降低的新方法，其主要目的在于还原钒和镍。 该过程使用电力来加速脱金属过程，但是仅使用电流的电流来加速反应，而不是电流的电解效应。 该方法通过在80〜200℃的较低温度范围内添加相间表面活性剂和相转移催化剂进行，并实现钒和镍的金属含量降低。 通过添加反应，用硫化氢，二氧化碳等处理胺溶液的水相醇衍生物，使其更适合携带更多的电流，并使其更具有金属还原活性。
