  An object of the present invention is to provide a desulfurizing and refining method for hydrocarbon oil for reducing sulfur compounds to an extremely low concentration at a relatively low equipment cost and operating cost. The method for desulfurizing hydrocarbon oils comprises causing a hydrocarbon oil containing at least one sulfur compound selected from the group consisting of thiophene compounds, benzothiophene compounds, and dibenzothiophene compounds or a hydrocarbon oil further containing aromatic hydrocarbons to come in contact with a solid acid catalyst and/or activated carbon containing a transition metal oxide. The solid acid catalyst is preferably a solid superacid catalyst selected from sulfated zirconia, sulfated alumina, sulfated tin oxide, sulfated iron oxide, tungstated zirconia, and tungstated tin oxide.

  Disclosed is a method for desulfurization of a hydrocarbon oil (e.g., kerosene which is a raw fuel for a fuel cell) which can effectively remove benzothiophenes and dibenzothiophenes contained in the hydrocarbon oil under mild conditions to produce a desulfurized hydrocarbon oil having a significantly low sulfur content. The method comprises the step of desulfurizing the hydrocarbon oil such as kerosene containing benzothiophenes and dibenzothiophenes with the combination of a solid acid-type desulfurizing agent and an active carbon-type desulfurizing agent. This method can provide a hydrocarbon oil having a significantly low sulfur content. By using the hydrocarbon oil, the operation or maintenance of a fuel cell system can be made easily, a fuel cell itself can be miniaturized in size, and the lifetime of a desulfurizing agent in a desulfurization apparatus equipped in a fuel cell system can be prolonged.

  本发明公开了一种碳氢化合物油（例如作为燃料电池原燃料的煤油）的脱硫方法，该方法可在温和条件下有效去除碳氢化合物油中所含的苯并噻吩和二苯并噻吩，从而生产出硫含量明显较低的脱硫碳氢化合物油。 该方法包括使用固体酸型脱硫剂和活性碳型脱硫剂对含有苯并噻吩和二苯并噻吩的烃类油（如煤油）进行脱硫的步骤。这种方法可以提供一种硫含量明显较低的碳氢化合物油。通过使用这种碳氢化合物油，可以使燃料电池系统的操作或维护变得简单，燃料电池本身的尺寸可以小型化，燃料电池系统中配备的脱硫装置中的脱硫剂的使用寿命可以延长。

  Deep desulfurization of hydrocarbon feeds containing undesired organosulfur compounds to produce a hydrocarbon product having low levels of sulfur, i.e., 15 ppmw or less of sulfur, is achieved by flashing the feed at a target cut point temperature to obtain two fractions. A low boiling temperature fraction contains refractory, sterically hindered sulfur-containing compounds, which have a boiling point at or above the target cut point temperature. A high boiling temperature fraction, having a boiling point below the target cut point temperature, is substantially free of refractory sulfur-containing compounds. The high boiling temperature fraction is contacted with isomerization catalyst, and the isomerized effluent and the low boiling temperature fraction are combined and contacted with a hydrotreating catalyst in a hydrodesulfurization reaction zone operating under mild conditions to reduce the quantity of organosulfur compounds to an ultra-low level.

  通过在目标切割点温度下闪蒸进料，获得两个馏分，对含有不需要的有机硫化合物的碳氢化合物进料进行深度脱硫，生产出硫含量低（即硫含量不超过 15 ppmw）的碳氢化合物产品。低沸点馏分含有难溶的、立体受阻的含硫化合物，其沸点等于或高于目标切点温度。高沸点馏分的沸点低于目标切点温度，基本上不含难熔含硫化合物。高沸点温度馏分与异构化催化剂接触，异构化流出物和低沸点温度馏分合并，并在温和条件下运行的加氢脱硫反应区与加氢处理催化剂接触，以将有机硫化合物的数量降至超低水平。
