Title:
輸送燃料のブレンド用成分からの硫黄除去のための多重ステージプロセス
Document Type and Number:
Japanese Patent JP4417104
Kind Code:
B2
Abstract:
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 integrated, multistage processes which include pretreatment of a light naphtha with a solid adsorbent to remove basic nitrogen containing compounds, chemical conversion of one or more of the sulfur-containing 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.
