The increasing demand for optimization in process control of reactive syste
ms necessitates the development of fast and reliable software for the numer
ical computation of optimal controls taking into account the special struct
ures of the chemical systems under investigation. A recently developed algo
rithm based on partially reduced SQP methods is used for the computation of
optimal controls following the direct approach. In this work, this algorit
hm is coupled with a package for the simulation of homogeneous reactive sys
tems, which provides the specific routines for the description of the probl
em at hand. The combined code takes advantage from the fact that the number
of influence variables to be determined is rather low compared with the ov
erall number of variables. For example, the computation tool developed is a
pplied to study the homogenous oxidative coupling of methane. (C) 2000 Else
