Notes:
The performance of the industrial HCN synthesis Andrussow reactor on a Pt gauze catalyst is simulated using rate equations for 13 simultaneous unimolecular and bimolecular surface reactions. Individual rates have been determined experimentally for reactants, intermediates, and products on polycrystalline Pt, and the model therefore contains no adjustable parameters except for reactant flux limits. Predicted selectivities of HCN formation agree quite well with those observed in commercial reactors, and a distinct optimum with feed composition is obtained near that observed experimentally. In addition, behaviors are predicted at compositions, pressures, and temperatures inaccessible to the commercial reactors. Both isothermal and nonisothermal situations are examined. Questions concerning the validity of models, reactant flux limits, and the decoupling of simultaneous surface reactions are considered.
