Boron-substituted graphite, which contains N-bonded boron atoms in a small proportion relative to whole substituted boron atoms, is produced by heating a feed fine particulate mixture of an infusibilized carbonaceous material and a boron compound such that the carbonaceous material is carbonized into a carbon structure, raising a temperature of the resulting heated fine particulate mixture promptly to a graphitization treatment temperature in an inert atmosphere unreactive with boron, retaining the graphitization treatment temperature for a time sufficient to allow graphitization of the carbon structure to proceed to a desired extent, and then quickly cooling the resulting graphitized mixture. The boron-substituted graphite is useful as a negative electrode in a lithium-ion secondary battery.

A method for decreasing the concentration of a chlorinated aromatic compound in the exhaust gas from a combustion furnace. The exhaust gas from the combustion furnace is passed through a bag filter. The concentration of the chlorinated aromatic compound in the exhaust gas is measured and the operating temperature of the bag filter is adjusted based on the measured concentration of the chlorinated aromatic compound in order to decrease the concentration of the chlorinated aromatic compound in the exhaust gas.
