    摘要: Gas adsorbent and process for producing same. A zeolitic or silica-alumina adsorbent is heat treated in a carbon atom-containing gas or a gaseous mixture consisting of a carbon atom-containing gas and an inorganic gas at 100.degree. to 700.degree. C. to produce the gas adsorbent. The gas adsorbent has carbon particles ranging in size from about 0.01 to about 10 .mu.m adhering on the surface or in pores thereof.

    摘要: It is possible to obtain at high yield a carbonaceous material suitable for carbon electrodes of electrical double layer capacitors and having superior capacitance by means of a method comprising a halogenation treatment step wherein a halogenated dry-distilled charcoal is obtained by bringing a dry-distilled charcoal into contact with a halogen gas; and by a dehalogenation treatment step wherein a part or all of the above-mentioned halogen in said halogenated dry-distilled charcoal is eliminated. In addition, it is possible to obtain carbonaceous material for electrical double layer capacitors, which has a large capacitance at rapid discharge and excellent shape, by means of conducting a molding treatment step in which a molded article is made by crushing a dry-distilled charcoal and adding a binding agent; and a carbonization treatment step in which the above-mentioned molded article is heated in an inert gas atmosphere before conducting the halogenation treatment.

    摘要: A halogen treatment is conducted comprising: a halogenation step wherein a halogenation heat treatment for preparing a halogenated carbonized charcoal is conducted in which the carbonized charcoal is brought into contact with halogen; and a dehalogenation step wherein a dehalogenation treatment is conducted in which a part of or all halogen atoms in the halogenated carbonized charcoal are eliminated. A porous carbonaceous material is obtained at a high yield, and the amounts of nitrogen, oxygen, carbon dioxide, and methane adsorbed by this porous carbonaceous material are large. When this porous carbonaceous material is used as an electrical double layer capacitor carbon, the electrostatic capacity is increased compared to conventional carbonaceous materials. Consequently, a carbonaceous material is obtained which has micopores and/or sub-micropores which are suitable for the adsorption of small molecules such as nitrogen, and for storage of electrochemical energy.

    摘要: Disclosed is a carbon negative electrode material containing microparticles of hard carbon. The pores in the carbon microparticles have an inlet diameter such that an organic solvent in an electrolyte of a lithium secondary cell is substantially impermeable and that lithium ions are permeable. Use of such carbon negative electrode material as a negative electrode enables to provide a lithium secondary cell with excellent cell capacity, in which charge capacity and discharge capacity are improved and irreversible capacity is minimized.
