    • An ignition coil for an internal combustion engine is mainly made up of a transformer part and a control circuit part and a connecting part, and the transformer part is made up of a iron core which forms an open magnetic path, magnets, a secondary spool, a secondary coil, a primary spool and a primary coil. By respectively setting the cross-sectional area SC of the iron core between 39 to 54 mm2, the ratio of the cross-sectional area SM of the magnets with the cross-sectional area SC of the iron core in the 0.7 to 1.4 range, the ratio of the axial direction length LC of the iron core with the winding width L of the primary and secondary coils in the 0.9 to 1.2 range, and the winding width L in the 50 to 90 mm range, the primary energy produced in the primary coil can be increased without increasing the external diameter A of the case.

    • Detergent-quality linear alkylaromatics are recovered from an alkylation reactor effluent containing polymeric byproducts, such as dimers and trimers of the olefinic feedstock. The effluent stream passes to another reactor operating at a higher temperature than the first reactor. Heavy alkylate is separated from the detergent-quality linear alkylaromatics by conventional separation methods such as distillation. This invention decreases the concentration of polymeric byproducts in the linear alkylaromatics. The benefits of this invention include a higher linearity and/or a lower bromine index in the detergent-quality linear alkylaromatic product, as well as a lower color after sulfonation of the linear alkylbenzene sulfonate.
    • 从含有聚合副产物的烷基化反应器流出物(例如烯属原料的二聚体和三聚体)中回收洗涤剂质量的线性烷基芳烃。 流出物流进入在比第一反应器高的温度下操作的另一个反应器。 通过常规的分离方法如蒸馏,将重质烷基化物与洗涤剂质量的线性烷基芳烃分离。 本发明降低了线性烷基芳烃中聚合副产物的浓度。 本发明的优点包括洗涤剂质量线性烷基芳族产物中较高的线性和/或较低的溴指数,以及直链烷基苯磺酸盐磺化后的较低颜色。

    • A process for the continuous isomerization of an alkane to produce an isomerized product through contacting the alkane with a simulated moving bed acting as a catalyst for isomerization and an adsorbent for the alkanes has been developed. The alkane may be n-butane and the isomerized product 2-methylpropane, the alkane may be n-pentane and the isomerized product 2-methylbutane or 2,2-dimethylpropane, the alkane may have from 6 up to about 8 carbon atoms with no more than one methyl branch and the isomerized product having the same number of carbon atoms and at least two methyl branches, or the reactant may be a mixture of the foregoing alkanes with the corresponding isomerized products being formed. In a zone of the simulated moving bed, the alkanes are catalytically isomerized to form the isomerized products. The unreacted alkanes are adsorbed, and the isomerized products are collected. In a first subsequent zone of the simulated moving bed, a large portion of the unreacted alkanes are desorbed using a desorbent. In a second subsequent zone of the simulated moving bed, residual adsorbed alkanes are desorbed using a mixture of desorbent and isomerized products, and the desorbed residual alkanes may be removed from the simulated moving bed or may be reacted to form additional isomerized products. The isomerized products are removed from the simulated moving bed and collected. The process may also be used to effect other chemical reactions with the concurrent separation of product.
    • 已经开发了通过使烷烃与用作异构化的催化剂的模拟移动床和用于烷烃的吸附剂使烷烃连续异构化以产生异构化产物的方法。 烷烃可以是正丁烷,异构化产物2-甲基丙烷,烷烃可以是正戊烷,异构化产物2-甲基丁烷或2,2-二甲基丙烷,烷烃可以具有6个至约8个碳原子,没有 多于一个甲基支链和具有相同数目的碳原子和至少两个甲基支链的异构化产物,或者反应物可以是前述烷烃与形成相应的异构化产物的混合物。 在模拟移动床的区域中,烷烃被催化异构化以形成异构化产物。 未反应的烷烃被吸附,收集异构化产物。 在模拟移动床的第一后续区域中,大部分未反应的烷烃使用解吸剂解吸附。 在模拟移动床的第二个随后的区域中,残余吸附的烷烃使用解吸剂和异构化产物的混合物解吸,并且解吸的残余烷烃可以从模拟的移动床中除去,或者可以反应形成另外的异构化产物。 将异构化产物从模拟移动床上取出并收集。 该方法也可用于通过产品的同时分离来实现其它化学反应。
