A position of active carbons in the ecology and economy, new technologies of their production
Abstract
At present the application of adsorption technologies based on active carbons is widely developing at all the world. That is followed by three circumstances: firstly, it provides the receiving of the products of high degree of the purity in many productions; secondly, it allows the introduction of high intensified technologies; thirdly, that is the most important, it allows create new products and fields of their application. Their using helps to solve a number of the tasks in the economy, ecology and defense of the country. Total tonnage of active carbons production at the world is 1 million 250 thousand tons at year and its increase is surely 5% at year. At present in Russia one produces less than 3 thousand tons of active carbons at year instead of necessary 70 thousand tons at year and buys up nearly 25 thousand tons from abroad. So, as at the plan of a replacement of import products as at the plan of a speedily development of powers of active carbons production in the country there is very actual to suggest effective technologies of their production based on domestic raw material. By the authors two more progressive technologies of active carbons receiving are developed. They meet the modern requirements of quality of carbon adsorbents.
-The Technology of DAS – the producing of active carbons based on anthracite by vapor-gaseous method; allows decrease to the minimum a quantity of technological studies und receive an adsorbent with the high microspores volume to unit of volume – 0.17 cm3/cm3.
-The Technology of UPK – the producing of active carbons based on coal-tar composition according to the most leading technology at the world with wide fields of their application.
Thus, the fastest organization of new manufactures of active carbons based on domestic coalmeasures in Russia will mighty incite to the development of productivity and provide a high quality of environmental protection. That confines oneself to the conception of stable development and creation of high-qualified human life.
