  在Pd / C和HZSM-5催化剂上各种甲氧基取代的木质素单体的水相加氢脱氧研究†

  摘要：

  在2 MPa的H 2（环境温度）下，使用Pd / C和HZSM-5催化剂的组合，已经研究了木质素单体通过加氢脱氧（HDO）进行水相催化提质的方法。选择具有不同甲氧基数目的模型单体，包括苯酚，茴香醚，愈创木酚和2，6-二甲氧基苯酚，作为木质素模型化合物。机理研究表明，通过氢化和脱水（水解）过程，分别由Pd / C和HZSM-5催化。优选在较低温度下氢化，而较高温度有利于除去含氧官能团。还系统地研究了甲氧基对这些单体的HDO的影响。基本上，由于空间约束和给电子羟基的抑制，多取代单体的转化比单取代单体的转化更困难。通过将温度提高到413 K，可以显着提高从苯酚和苯甲醚对环己烷的选择性。但是，即使在高温下使用具有多取代基的模型化合物（愈创木酚和2,6-二甲氧基苯酚），环己酮也比环己烷更易制得513 K以上。

  公开（公告）日：2011-08-18

  Redox flow devices are described in which at least one of the positive electrode or negative electrode-active materials is a semi-solid or is a condensed ion-storing electroactive material, and in which at least one of the electrode-active materials is transported to and from an assembly at which the electrochemical reaction occurs, producing electrical energy. The electronic conductivity of the semi-solid is increased by the addition of conductive particles to suspensions and/or via the surface modification of the solid in semi-solids (e.g., by coating the solid with a more electron conductive coating material to increase the power of the device). High energy density and high power redox flow devices are disclosed. The redox flow devices described herein can also include one or more inventive design features. In addition, inventive chemistries for use in redox flow devices are also described.
