Abstract: There is disclosed a method of recovering chlorine gas from calcium chloride comprising the steps of introducing calcium chloride into a heat-resistant vessel which is provided with a gas inlet pipe and a gas outlet pipe, heating the calcium chloride up to at least the melting point thereof while introducing an inert gas from the gas inlet pipe into the vessel to produce fused salt of calcium chloride, and heating the interior of the vessel up to at least 1073K and switching a gas to be introduced from the gas inlet pipe from the inert gas to oxygen to allow the fused salt of calcium chloride to react with the oxygen to obtain chlorine gas and calcium oxide, the chlorine gas being subsequently rapidly and continuously discharged from the vessel through the gas outlet pipe.

Abstract: It is acknowledged that an electric double layer capacitor is markedly superior in power density and cycle characteristics to a secondary battery. However, a higher energy density is required to apply it to a power supply of hybrid vehicle, electric vehicle or the like. The present inventors have found that a carbonaceous material containing copper or a compound of copper exhibits excellent characteristics as an electrode material for capacitor and can realize a capacitor having a large capacity. In the electrode material and the capacitor, copper or a compound of copper exists in the amount of 0.8 to 30 parts by weight calculated on the metal basis based on 100 parts by weight of the carbonaceous material, particularly preferably.

Abstract: Disclosed are electrode materials that exhibit very sharp pore size distribution within the range of mesopores and include pores having a pore diameter within a range of X±&agr; nm (3.0≦X<10, &agr;=1.0; range of pore size distribution) of which volume accounts for 15% or more of the total volume of mesopores having a pore diameter within a range from 2.0 to 50 nm, and are suited for use in electric double layer capacitor, battery or the like of large capacitance and discharge of large current. These electrode materials are obtained by adding at least one transition metal or at least one transition metal compound to a carbon material or a carbon material precursor, and subjecting to a heat treatment at a temperature of 600° C. or higher.

Abstract: A granular active carbon for natural-gas occlusion is disclosed which can occlude natural gas at a relatively low pressure and has a high natural-gas occlusion capacity. The granular active carbon for natural-gas occlusion has first and second pores for the occlusion of constituent gas molecules of natural gas. The first pores each has a diameter d1, satisfying 2d<d1≦2.5d, while the second pores each has a diameter d2 satisfying 5d<d2≦6d, wherein d is the diameter of the constituent gas molecules.
