摘要:
The invention relates to the purification of pentafluoroethane (F125) containing chloropentafluoroethane (F115) by vapor-phase catalytic hydrogenolysis. A catalyst based on palladium deposited on aluminium trifluoride is employed.
摘要:
The invention relates to a continuous process for the preparation of aluminium nitride by the carbonitriding of alumina.According to this process, the reaction, which employs alumina, carbon and nitrogen, is carried out in a moving-bed reactor characterized in that the reaction area has a plurality of conduits.
摘要:
The invention relates to a continuous process for the preparation of aluminum nitride by the carbonitriding of alumina. According to this process, a reaction that uses alumina, carbon, and a resin that generates carbon by pyrolysis is performed in a methodical reactor. The invention relates to a continuous process for the preparation of aluminum nitride by the carbonitriding of alumina.
摘要:
Aluminum nitride (AlN) is continuously produced by continuously carbonitriding a continuously replenished charge of alumina, for example successive charges of alumina/carbon extrudates, in a reaction zone comprising at least one conduit, the ratio of the exchange surface area/volume of which at least one conduit ranging from 5 to 50 m.sup.-1, preferably from 10 to 50 m.sup.-1, and continuously withdrawing product AlN therefrom.
