    • The present invention discloses a new type of high performance polymer membranes derived from aromatic polyimide membranes and methods for making and using these membranes. The polymer membranes described in the present invention were derived from aromatic polyimide membranes by crosslinking followed by thermal treating. The aromatic polyimide membranes were made from aromatic polyimide polymers comprising both pendent hydroxy functional groups ortho to the heterocyclic imide nitrogen and cross-linkable functional groups in the polymer backbone. The high performance polymer membranes showed significantly improved permeability for gas separations compared to the aromatic polyimide membranes without any treatment. The high performance polymer membranes also showed significantly improved selectivity for gas separations compared to the thermal-treated but non-UV-crosslinked aromatic polyimide membranes. The high performance polymer membranes of the present invention are suitable for liquid, gas, and vapor separations, as well as for catalysis and fuel cell applications.
    • 本发明公开了一种衍生自芳族聚酰亚胺膜的新型高性能聚合物膜以及制造和使用这些膜的方法。 本发明中描述的聚合物膜通过交联然后进行热处理从芳族聚酰亚胺膜得到。 芳族聚酰亚胺膜由芳族聚酰亚胺聚合物制成,其中包含杂环酰亚胺氮原子的邻接羟基官能团和聚合物主链中的可交联官能团。 与没有任何处理的芳族聚酰亚胺膜相比,高性能聚合物膜显示出显着改善气体分离的渗透性。 与热处理但非UV交联的芳族聚酰亚胺膜相比,高性能聚合物膜还显示出对气体分离的选择性显着提高。 本发明的高性能聚合物膜适用于液体,气体和蒸汽分离,以及催化和燃料电池应用。

    • The present invention discloses new types of polybenzoxazole-based mixed matrix membranes and methods for making and using these membranes. The polybenzoxazole-based mixed matrix membranes are prepared by fabricating a polyimide-based mixed matrix membrane by dispersing molecular sieve particles in a continuous aromatic polyimide matrix with pendent hydroxyl groups ortho to the heterocyclic imide nitrogen; and then converting the polyimide-based mixed matrix membrane to a polybenzoxazole-based mixed matrix membrane by heating between 200 and 600C under inert atmosphere or vacuum. The polybenzoxazole-based mixed matrix membranes of the present invention can be fabricated into any convenient geometry such as flat sheet (or spiral wound), tube, hollow fiber, or thin film composite. These polybenzoxazole-based mixed matrix membranes exhibit high thermal stability, significantly higher selectivity than the neat polybenzoxazole polymer membranes, and much higher permeability than traditional mixed matrix membranes.
    • 本发明公开了新型的基于苯并恶唑的混合基质膜,以及制造和使用这些膜的方法。 基于聚苯并恶唑的混合基质膜通过将分子筛颗粒分散在具有与杂环酰亚胺氮原子相邻的侧羟基的连续芳族聚酰亚胺基体中制备聚酰亚胺基混合基质膜来制备; 然后通过在惰性气氛或真空下在200℃至600℃之间加热将聚酰亚胺基混合基质膜转变成聚苯并恶唑类混合基质膜。 本发明的基于聚苯并恶唑的混合基质膜可以制成任何方便的几何形状,例如平板(或螺旋缠绕),管,中空纤维或薄膜复合材料。 这些基于聚苯并恶唑的混合基质膜具有高的热稳定性,比纯聚苯并恶唑聚合物膜显着更高的选择性,并且比传统的混合基质膜具有更高的渗透性。

    • A process for desulfurizing a gasoline stream while continuing to maintain the octane rating of the blend stock. A gasoline stream containing sulfur compounds and olefins is introduced into a fractionation zone to produce a low boiling fraction containing mercaptan sulfur compounds and olefins, a mid boiling fraction containing thiophene and olefins, and a high boiling fraction containing sulfur compounds. The low boiling fraction containing mercaptan sulfur compounds is contacted with an aqueous alkaline solution to selectively remove mercaptan sulfur compounds. The mid boiling fraction containing thiophene is extracted to produce a raffinate stream containing olefins and having a reduced sulfur content relative to the mid boiling fraction and a hydrocarbonaceous stream rich in thiophene. The resulting hydrocarbonaceous stream rich in thiophene and the higher boiling fraction containing sulfur compounds is reacted in a hydrodesulfurization reaction zone to produce a hydrocarbonaceous stream having a reduced sulfur concentration.
