    • The present disclosure relates to a process for reducing the amount of aromatics in a raw feed stream comprising hydrocarbons, more than 200 ppmw sulfur or 1000 ppmw sulfur as either hydrocarbon heteroatoms or as other sulfide compounds as well as at least 10% by weight di-aromatics or poly-aromatics and at least 30% by weight aromatics in total said process comprising the steps of hydrotreating said raw feed stream in the presence of hydrogen and a material catalytically active in hydrotreatment with a severity resulting in a conversion of sulfur hydro-carbon heteroatoms to hydrogen sulfide of at least 50% providing a pre-treated stream, separating said pre-treated stream at least into a second stage feed stream and a stream rich in hydrogen sulfide, directing said second stage feed stream to contact a material catalytically active in hydrocracking and ring opening, and to contact a material catalytically active in saturation of aromatics, wherein the material catalytically active in hydrocracking and ring opening is positioned upstream, downstream or mixed with said material catalytically active in saturation of aromatics, and withdrawing a dearomatized stream, wherein said the amount of aromatics of said dearomatized stream is less than 50%, 70%, 90% or 95% of the amount of aromatics in said raw feed stream, with the associated benefit of said process of providing efficient dearomatization with low yield loss.
    • 本发明涉及一种用于减少包含烃的粗原料流中的芳烃量,作为烃杂原子或作为其他硫化物化合物的多于200ppmw硫或1000ppmw硫的方法,以及 至少10重量%的二芳族化合物或多芳族化合物以及总计至少30重量%的芳族化合物,所述方法包括以下步骤:在氢气和催化活性加氢处理物质存在下加氢处理所述原料物流,产生严重性 在将硫氢碳杂原子转化为至少50%的硫化氢以提供预处理的物流时,将所述预处理的物流至少分离成第二阶段进料流和富含硫化氢的物流,引导所述第二阶段 进料物流接触在加氢裂化和开环中催化活性的物质,并接触在芳族化合物的饱和中催化活性的物质,其中催化剂物质 具有催化活性的所述材料在饱和芳族化合物和取出脱芳构化料流的情况下定位在上游,下游或与所述材料混合,其中所述脱芳构化料流的芳族化合物的量小于50%,70%,90% %或95%的所述原料物流中的芳族化合物的量,所述方法的相关益处是提供具有低产率损失的有效脱芳化作用。
