The design and construction of two experimental platforms for the testing of heterogeneous catalysts are described. The first is intended for a vapour phase dimerisation process over a solid catalyst. Issues connected with refinement of that experimental arrangement are described and an operational specification defined. No catalyst testing is reported for this arrangement. The second apparatus is designed to explore carbonyl chloride (phosgene) synthesis from the reaction of CO and Cl2 over high surface area carbon catalysts.

After the experimental configuration of the phosgene test facility has been described, a series of reaction test data using a Donau Supersorbon K40 catalyst is presented. Steady state phosgene production was established and is associated with an activation energy of 28 kJ mol-1. Van’t Hoff plots were adopted to obtain the rate law for this reaction and a reaction scheme is proposed.

Overall this study is intended to provide training in the design, construction and testing of heterogeneous catalyst test apparatus. Further, the phosgene synthesis measurements are intended to provide insight into an important application of process chemistry relevant to an isocyanate production chain.
