Dechlorination of Aromatics Investigated in Micro Reactors

3 Dechlorination of Aromatics Investigated in Micro Reactors Cas/liquid reaction 15 [CL 15] Dechlorination of p-chlorophenol to phenol 

This process involves a series of reactions, including dissolution, hydrogen reactions and chlorine withdrawal [20], The second type of reactions include reduction of protons at the catalyst by electron transfer yielding hydrogen radicals that are consumed by reaction or give elemental hydrogen otherwise. 

As catalyst, a Pd/Fe system is used, having finely dispersed Pd clusters ( 1 pm) on the Fe surface [20] (see also original citations in [20]). A considerable portion of the surface remains uncovered, exposing Fe for reaction. 

The micro reactor consisted of a pair of iron plates coated with Pd catalyst placed on disk-type polypropylene holders [20]. This micro channel device was encased in a stainless-steel housing. The thickness of the catalyst layer was approximately 5.0 pm 10 mg catalyst was deposited per plate, so giving 20 mg in total. The specific surface area of the catalyst was 3.6 0.4 m g
