    • The invention provides a lithium secondary battery using hydric boron carbonitride which is a layered compound represented by BC.sub.x N.sub.y H.sub.z, where 0.5.ltoreq.x.ltoreq.12, 0.7.ltoreq.y.ltoreq.1.5, and 0.01.ltoreq.z.ltoreq.3, as the active material of the negative electrode. This compound is obtained by a CVD process. The electrolyte is a solution of a lithium salt in an organic solvent. The material of the positive electrode is an oxide such as MnO.sub.2 or V.sub.2 O.sub.5, a sulfide such as MoS.sub.2 or TiS.sub.2 or a conductive organic polymer such as polyaniline. In this secondary battery Li is smoothly intercalated in and released from the hydric boron carbonitride of the negative electrode, and the energy density with respect to the active material of the negative electrode is sufficiently high. This battery bears a fairly large number of charge-discharge cycles. Also it is possible to use hydric boron carbonitride as the active material of the positive electrode of a lithium secondary battery in combination with negative electrode of metallic Li or hydric boron carbonitride with intercalation of a larger amount of Li.
    • 本发明提供一种锂二次电池,其使用碳氮化硼,其是由BCxNyHz表示的层状化合物,其中0.5≤x≤12,0.7≤y≤1.5,和0.01≤z= 3,作为负极的活性物质。 该化合物通过CVD法获得。 电解质是锂盐在有机溶剂中的溶液。 正极的材料是诸如MnO 2或V 2 O 5的氧化物,诸如MoS 2或TiS 2的硫化物或诸如聚苯胺的导电有机聚合物。 在该二次电池中,Li被平滑地插入负极的碳氮化硼中并从其释放,并且相对于负极的活性物质的能量密度足够高。 该电池的充放电次数相当多。 另外,可以使用氢碳氮化硼作为锂二次电池的正极的活性物质与金属Li或碳氮化硼的负极结合,并插入更多量的Li。

    • A catalyst carrier composed of a refractory inorganic oxide has a rotationally symmetrical shape having a hollow portion, such as a doughnut shape. An outer peripheral surface and the inner peripheral surface separating the hollow portion are linked by curved surfaces, and the height h of the carrier along the rotational symmetry axis is less than the outer diameter Do of the carrier. Using a catalyst having this carrier shape for a fixed bed makes it possible to prevent granular substances from causing catalyst plugging, and catalyst life can be extended because the catalyst-induced differential pressure increase is low even when granular substances accumulate on the catalyst. It is also possible to prevent the reaction fluid from undergoing channeling. Also provided is a hydrogenation reactor whose fixed bed is packed with the catalyst.
    • 由耐火无机氧化物构成的催化剂载体具有中空部分的旋转对称形状,例如环形。 分离中空部的外周面和内周面通过曲面连结,沿着旋转对称轴的载体的高度h小于载体的外径Do。 使用具有这种载体形状的催化剂作为固定床使得可以防止颗粒物质引起催化剂堵塞,并且即使在催化剂上积累颗粒物质时催化剂诱导的差压增加较小,也能够延长催化剂寿命。 还可以防止反应流体进行通道化。 还提供了一种氢化反应器,其固定床装有催化剂。
