日本活性炭品种及其发展动向

The Variety of Active Carbon and Its DynamicDevelopment in Japan

近二三十年来，活性炭在日本炭材料中处于显赫位置，品种越来越多，产量一直稳步增长。在日本，活性炭主要用于防毒面具、气体和液体的精制、溶剂的脱色、催化剂等方面。本文就日本一些活性炭新品种的特点、制各方法、应用及日本活性炭产量及供需情况作简要介绍。

Abstract Active carbon occupies a prominent position in the carbon materials in Japan.It is mainly used in manufacture of gas mask , gas and liquid purification , decoloration ofsolvent and in preparation of catalysts. The annual production of active carbon in Japanis about 70, 000t. In recent 20 years the active carbons produced in Japan and noted fornew characteristies are globular, fibrous , beehive-like active carbons and other newtypes. This paper focuses on describing the fibrous and beehive - like active carbons ,their annual output , supply and demand. Fianlly, in view of the dynamics of active car-bon industry in Japan , the author gives his own view on the dynamic development of ac-tive carbon in China.
