  The invention disclosed relates to a process for refining a hydrocarbon feed to make substantially styrene-free C6-C8 aromatic hydrocarbons (BTX). The hydrocarbon feed, for example, unhydrotreated pyrolysis gasoline, is distilled to make a BTX rich stream containing styrene which is fractionated to separate C6 and C7 hydrocarbons from C8 hydrocarbons including styrene. Styrene in the C8 hydrocarbons reacts in the presence of a selective etherification catalyst with a C1-C3 lower alkyl alcohol to form the corresponding styrene ether, which is then separated by distillation into a styrene ether stream and a C8 hydrocarbons rich stream. The C8 hydrocarbons rich stream is then re-mixed with the C6 and C7 hydrocarbons, and sent to hydrogenation reactors to remove sulphur and olefinic hydrocarbons to form substantially styrene-free BTX.

  本发明涉及一种精制烃类原料的工艺，以制备几乎不含苯乙烯的C6-C8芳烃（BTX）。例如，未经加氢处理的裂解汽油的烃类原料被蒸馏以制备富含苯乙烯的BTX流，然后进行分馏以将C8烃类中的苯乙烯与C6和C7烃类分离开来。C8烃类中的苯乙烯在选择性醚化催化剂的存在下与C1-C3低碳烷基醇反应，形成相应的苯乙烯醚，然后通过蒸馏将其分离成苯乙烯醚流和富含C8烃类的流。然后将富含C8烃类的流与C6和C7烃类重新混合，并送入加氢反应器中去除硫和烯烃烃类，以形成几乎不含苯乙烯的BTX。

  Various substantially styrene-, methylstyrene- and ethylbenzene-free C6-C9 aromatic hydrocarbon blends are produced from a hydrocarbon feed stream containing C5-C9 aromatic hydrocarbons including styrene, methylstyrene and sulphur compounds by first separating the stream into a distillate containing C5-C7 hydrocarbons, and a bottoms fraction containing C8 and C9 hydrocarbons; and converting the styrene and methylstyrene to their corresponding ethers by reacting with a C1-C3 lower alcohol in the presence of a selective acidic etherification catalyst. The effluent may be sent to a gasoline pool for blending or the effluent is separated by distillation into an ether stream and either a C8 or a C8-C9 aromatic hydrocarbon rich stream. The C5-C7 distillate is hydrogenated.

  从含有苯乙烯、甲基苯乙烯和硫化物的C5-C9芳烃烃流中，首先将其分离成含有C5-C7烃的馏分和含有C8和C9烃的底部馏分，然后在选择性酸性醚化催化剂的存在下，通过与C1-C3低级醇反应将苯乙烯和甲基苯乙烯转化为相应的醚。可以将流出物送入汽油混合池中进行混合，或者通过蒸馏将流出物分离成醚流和C8或C8-C9芳烃富集流。C5-C7馏分被加氢。生产各种基本不含苯乙烯、甲基苯乙烯和乙基苯的C6-C9芳烃混合物。

  A molding compound composition of the present invention comprises a resin composition, for example, unsaturated polyester, a succinic acid derivative, and a thickening agent such as magnesium oxide, and the moisture content thereof is adjusted in a range of from 0.1 to 0.45 percent by weight. A molding compound comprises the molding compound composition and reinforced fibers such as glass fibers, and the moisture content thereof is adjusted to be in a range of from 0.1 percent to 0.4 percent by weight. As shown in Fig. 1, the molding compound composition has excellent viscosity characteristics since the initial thickening action due to the thickening agent is restrained. Although the viscosity after thickened is lower than that of a conventional composition, the stickiness of the surface of the molding compound composition is reduced. The molding compound composition has high flowability and excellent impregnability, shows an abrupt viscosity increase after impregnation, and is thickened at higher speeds as compared with the conventional composition.

  本发明的一种模塑化合物组合物由树脂组合物（例如不饱和聚酯）、琥珀酸衍生物和增稠剂（例如氧化镁）组成，其含水量按重量计调整在 0.1%至 0.45%的范围内。模塑复合物由模塑复合物组合物和增强纤维（如玻璃纤维）组成，其水分含量按重量计调整为 0.1%至 0.4%。如图 1 所示，由于增稠剂的初始增稠作用受到抑制，因此模塑化合物组合物具有优异的粘度特性。虽然增稠后的粘度比传统组合物低，但模塑化合物组合物表面的粘性却降低了。与传统组合物相比，该模塑化合物组合物具有高流动性和出色的浸渍性，浸渍后粘度会突然增加，并能以更高的速度增稠。
