Filtration of the Catalysts

 

The catalytic process involving use of Palladium on Charcoal ( a heterogeneous type of catalyst ) the separation of catalyst from the products of the reaction is quite easy.  Most of the catalyst particles after the stoppage of agitator, settles at the bottom of the reactor under the influence of gravity.

A small fraction constituting less than two / three percent may however remain in suspended form.  The products of reaction being in liquid form can be subjected to filtration using notch filter with filter cloth having pore size of less than 15 microns.  A filter paper sheet may also be spread over the filter cloth to assist clear filtration.

Initially some catalyst particles may pass through filter cloth.  Such portion of the filtered liquid should be subjected to refiltration.  In case of small volumes, use of centrifuge may be mixed with the bulk quantity of catalyst lying in the reactor.  However it should be ensured  that catalyst particles collected on the filter paper or filter cloth do not get dried up as dried particles may catch fire.

Filtration of the Catalysts

Use of filter-aid, viz fuller's earth should be avoided as far as possible, as it eliminates the prospect of recycling as well as reactivation of catalyst.
