From the analytical relationship experimentally determined between the kinetic behavior in the 2-ethylhexanol dehydration on silica-aluminas prepared by silica gel impregnation and four control variables in the preparation (% Al/sub 2/O/sub 3/, drying temperature and pressure, and calcination temperature), optimum values of the preparation conditions of these catalysts have been calculated by means of a program of simulation of the catalyst utilization in reaction-regeneration cycles. Reaction-regeneration cycles have been carried out in an automated reactor under, previously calculated, optimum operating conditions. In these cycles, the catalyst used is the one prepared under the optimum values of the variables. In the same way, the optimum properties have been calculated, that is, the surface area, the pore volume, the total acidity, and the strong acidity that the silica-alumina catalysts must have for the studied reaction. Later, the effect of each of the properties in the production was analyzed. Results of the analysis are described.
