Abstract: A process for treating a light cracked naphtha to be used as an etherification feed stock is disclosed in which mercaptans, H2S and diolefins are removed simultaneously in a distillation column reactor using a reduced nickel catalyst. The mercaptans and H2S are reacted with the diolefins to form sulfides which are higher boiling than that portion of the naphtha which is used as feed to the etherification unit. The higher boiling sulfides are removed as bottoms along with any C6 and heavier materials. Any diolefins not converted to sulfides are selectively hydrogenated to mono-olefins for use in the etherification process.

Abstract: The general object of this invention is to provide an improved process for sweetening and desulfurizing sulfur-containing crude oil streams. Heating the sulfur-containing crude oil stream to an elevated temperature for an extended period of time while stirring and bubbling an inert gas into the crude accelerates the removal of sulfur containing gases from the crude oil stream. Furthermore, the addition of a polyalkylamine to the stirred crude oil can also greatly assist in the expulsion of sulfur containing gases. After processing under these conditions, the hydrogen sulfide producing capacity of the crude oil is reduced significantly, thus making the crude safer for transportation and handling by reducing the health and environmental risks.

Abstract translation: 本发明的总体目的是提供一种改善含硫原油流的脱硫和脱硫方法。 将硫含量的原油流加热至高温持续较长时间，同时搅拌并将惰性气体鼓入粗制品中加速从原油流中除去含硫气体。 此外，向搅拌的原油中加入聚烷基胺也可以极大地有助于排出含硫气体。 在这些条件下处理后，原油的硫化氢生产能力显着降低，因此通过降低健康和环境风险，使运输和处理更加安全。

Abstract: The present invention provides a process for thermosetting pitch fibers in reduced times, at low concentrations of oxygen and at higher temperatures than previously possible. Additionally, the present invention provides a pitch fiber which has an oxygen diffusion rate to the center of the fiber which is competitive with the rate of oxidation at the fiber's surface. Further, the present invention provides a high density pitch fiber batt which thermosets without loss of fiber structure.

Abstract: The present invention provides a method for producing hydrocarbon fuels with ultra-low levels of sulfur. The method involves catalytic oxidation of the sulfurous compounds within the hydrocarbon fuel, followed by extraction of the oxidized (and polarized) sulfurous compounds using a polar solvent. The present invention teaches the involvement of ethanol during catalytic oxidation. In this way, the oxidation catalyst has a dual-role in the oxidation process: firstly the catalyst directly oxidizes the sulfurous compounds, and secondly the oxidation catalyst converts of a small portion of the alcohol to the corresponding peroxy acid, which also helps to drive the oxidation process.
