  A process and system for reducing the sulfur content from a mixture of hydrocarbons and oxidized sulfur-containing hydrocarbons is provided by electrochemical decomposition. The electrochemical reactions occur under electrical potential and in the presence of an electrolyte solution that is effective promote decomposition of a portion of the oxidized sulfur compounds, to recover a hydrocarbon product having a reduced sulfur content while minimizing loss of hydrocarbon.

  提供了一种通过电化学反应降低碳氢化合物和氧化含硫碳氢化合物混合物中硫含量的工艺和系统。电化学反应在电势和电解质溶液存在下进行，电解质溶液能有效促进部分氧化硫化合物的分解，从而回收硫含量降低的碳氢化合物产品，同时最大限度地减少碳氢化合物的损失。
