Abstract
An oxychlorination catalyst precursor is described which is constituted by porous microspheroidal alumina particles impregnated with 3 to 7% by weight of cupric chloride (expressed in terms of the copper metal) and containing from 0.5 to 2% by weight of water, in which the copper is uniformly distributed over the entire surface area of the particles with a degree of non-uniformity not greater than .+-.7%. A process for the preparation of such a catalyst precursor is also described. The precursor is activated to give a catalyst which is readily fluidizable and which enables the oxychlorination of ethylene to dichloroethane to be carried out with high activity and selectivity values.
Claims5
Oxychlorination catalyst precursor constituted by porous microspheroidal alumina particles impregnated with cupric chloride, characterized in that:
- the cupric chloride content is from 3 to 7% by weight (expressed in terms of copper metal);
- the particles have a water content of from 0.5 to 2% by weight;
- and the copper is uniformly distributed over the entire surface area of each particle, with a degree of non-uniformity of not more than .+-.7%.
