A novel setup to study the effect of fast, high temperature pulses on catalytic reactions has been developed. The system is based on a microreactor and a generic catalyst support, with an integrated heater that allows for temperature changes up to 23

This paper describes a novel form of dynamic operation named pulsed activation method. It can be viewed as a form of periodic operation in which very fast temperature pulsing is used to induce chemical reactions directly and locally as needed. The ma

Kinetic models of reaction networks often feature sets of fast-reacting species. If the slow timescale is of interest these species can be assumed to be in equilibrium and using a lumping method a system of lower order is obtained. However, to obtain

The tuning of state-space model predictive control (MPC) based on reverse engineering has been investigated in literature using the inverse optimality problem ( [1] and [2]). The aim of the inverse optimality is to find the tuning parameters of MPC t

Dynamic optimization of industrial processes modeled by complex differential-algebraic equation systems is still a major challenge from an algorithmic point of view. We consider a special class of these problems, in which the objective is economic. T
