    • Economical processes are disclosed for the production of fuels of reduced sulfur content from a feedstock, typically derived from natural petroleum, wherein the feedstock is comprised of limited amounts of sulfur-containing organic compounds as unwanted impurities. The processes involve an integrated, multiple stage system for converting these impurities to higher boiling products by alkylation and removing the higher boiling products by fractional distillation. Advantageously, the processes include selective hydrogenation of the high-boiling fraction whereby the incorporation of hydrogen into hydrocarbon compounds, sulfur-containing organic compounds, and/or nitrogen-containing organic compounds assists by hydrogenation removal of sulfur and/or nitrogen. Products can be used directly as transportation fuels and/or blending components to provide, for example, more suitable components for blending into fuels which are more friendly to the environment.
    • 公开了用于生产通常衍生自天然石油的原料的硫含量降低的燃料的经济方法,其中原料由有限量的含硫有机化合物作为不想要的杂质组成。 该方法涉及通过烷基化将这些杂质转化成较高沸点产物并通过分馏除去较高沸点产物的综合多级体系。 有利地,该方法包括高沸点馏分的选择性氢化,由此通过氢化除去硫和/或氮来帮助将氢引入到烃化合物,含硫有机化合物和/或含氮有机化合物中。 产品可以直接用作运输燃料和/或混合组分,以提供例如更适合的组分用于混合到对环境更友好的燃料中。
