IMPROVED METHODS AND CATALYSTS FOR THE MANUFACTURE OF CARBONFIBRILS |
摘要 |
An improved catalyst for producing carbon fibrils is made by incorporating a n effective yield-enhancing amount of a car- boxylate into a fibril-forming catalyst. Alternatively, such a catalyst is made by coprecipitating a compound of a metal having fi- bril-forming catalytic properties and an aluminum and/or magnesium compound, optionally in the presence of carbon particles or carbon fibril aggregates. The catalyst may also be made by incorporating a compound of a fibril-forming metal onto magnesia particles in carbon particles or carbon fibril aggregates. The catalysts, methods of using them to form carbon fibrils and those car- bon fibrils are also disclosed.
