Reaction Schemes of Interest

Mixing effects on product distribution are of importance in mnltiple reactions because the impact on design and economics can be profonnd. In such reactions the desired product is one of two or more possible products. Economics are directly affected by yield of desired product, and both design and economics are affected by downstream separation requirements. 

The effects of mixing on selectivity have been most carefully investigated for a competitive-consecutive reaction of the type 

Ideal plug flow with perfectly mixed feed 0.861 

Imperfect tubular reactor 0.571 with turbulence parameters k = 0.008 m /s, 8 = 0.03 m /s, 10 s residence time 

Imperfect stirred tank 0.652 for 6280 L, Rushton turbine with N = 24.4 rpm, feed at impeller discharge

The example given above suffices to show the complexity of the solution of the differential equations for the most simple of reactions coupled to charge transfer at an electrode. Most reaction schemes of interest result in equations which cannot be solved analytically. Numerical methods have been used extensively to solve the equations for various mechanisms coupled to charge transfer. The most significant efforts in this field are the contributions by...
