Ziegler catalysts |
| abstract |
Ziegler catalytic system comprising an organo-metallic compound of a metal of Groups I to III of the Periodic Table and a compound of a heavy metal of Groups IV to VI supported on a carrier, the latter being an activated amorphous alumina or alumino-silicate containing from 0.3 to 30% by weight of salts of aluminum with oxygenated inorganic anions, or of a mixture of the latter with salts of aluminum with non-oxygenated inorganic anions, said inorganic anions being introduced into the amorphous alumina or alumino-silicate by contacting the latter with one or more acid solutions of the inorganic anions and the carrier being then activated by calcination at 250° - 700° C. |
