The optimization of bifunctional catalyst systems
TL;DR: In this article, an optimal profile of the bifunctional catalyst compositon along the length of the reactor that maximizes or minimizes the objective function is investigated, and for some limiting circumstances it is found that the profile takes on a simple form.

TL;DR: In this paper, a bifunctional catalytic reaction occurring under isothermal conditions in a tubular reactor was investigated and the optimal profile was obtained in a comparatively small number of iterations.
