一种烃油两相加氢方法
摘要：
本发明公开了一种烃油两相加氢方法，本发明通过将混合器设置在加氢反应器顶部，循环油管设置在加氢反应器内部，氢气与新鲜原料油和循环油在混合器中混合形成混合物流，混合物流后与催化剂接触进行加氢反应，反应流出物一部分作为循环油，另一部分进行分离。循环油通过循环油管在加氢反应器中循环，循环油管一端与混合器相连，另一端通过循环油泵与加氢反应器出口相连。该方法将混合器及循环油管设置在加氢反应器里，结构简单，大大节约了空间，降低了投资。
摘要（英）：

The invention discloses a hydrocarbon oil two-phase hydrogenation method. According to the invention, a mixer is arranged on the top of a hydrogenation reactor, a cycle oil tube is arranged in the hydrogenation reactor, hydrogen is mixed with fresh raw oil and cycle oil in the mixer to form a mixture flow, the mixture flow contacts with a catalyst and is hydrogenated, parts of the resulting reaction effluent are used as the cycle oil, and the other parts of the reaction effluent are separated. The cycle oil is cycled in the hydrogenation reactor through the cycle oil tube, one end of the cycle oil tube is connected with the mixer, and the other end of the cycle oil tube is connected with the outlet of the hydrogenation reactor through a cycle oil pump. The method which allows the mixer and the cycle oil tube to be arranged in the hydrogenation reactor has the advantages of simple structure, substantial space saving, and investment reduction.
