Catalytic Dehydrogenation of sec-butyl Alcohol

Data for the initial reaction rate for the catalytic dehydrogenation of sec-butyl alcohol to methyl ethyl ketone are given in Table 16.13 (Thaller and Thodos, 1960 Shah, 1965). The following two models were considered for the initial rate  

Temperature (°F) Pressure (atm) Feed Rate (Ib-moles/h) Initial Rate (rAl) lb-moles of alcohol/(h) (lb-catalyst) 

Model Temperature (°F) knxl02 (Ibmoles alcohol /(hr lb catalyst) kRxl02 (Ibmoles alcohol /(hr lb catalyst) KAxl02 (atm 1) 

Using the initial rate data given above do the following (a) Determine the parameters, kR, kH and KA for model-A and model-B and their 95% confidence intervals and (b) Using the parameter estimates calculate the initial rate and compare it with the data. Shah (1965) reported the parameter estimates given in Table 16.14.

This type of reactor has been used in the past to study solid-catalyzed gaseous reactions. Tajbl, Simons, and Carberry (3) used a CSTCR to study the highly exothermic oxidation of carbon monoxide on a commercial palladium catalyst. Ford and Perlmutter (2) used a CSTCR with a catalytic wall to study sec-butyl alcohol dehydrogenation. In both studies, the authors found that data were obtained more easily and accurately with a CSTCR.
