Catalytic Processes and Waste Valorization

Research Group

PROCAT-VARES research group works on the proposal, progress and innovation of processes of energy and environmental interest. The aim is to develop, at an international leading level, lines of research in Chemical Reaction Engineering that are up-to-date and focused on sustainable development. The development of this activity involves the training of researchers and technologists, the transmission of knowledge to the international scientific-technological community in the form of publications and collaboration with the industrial sector, on issues that combine academic, technological, social and industrial interest.

[New paper] Spectro-kinetics of the methanol to hydrocarbons reaction combining online product analysis with UV–vis and FTIR

The well-studied methanol to hydrocarbons reaction over a ZSM-5 zeolite catalyst has been used to develop a spectro-kinetic approach to obtain an overall reaction mechanism involving both retained species and gas-phase products. We combined two in situ spectroscopic techniques (ultraviolet–visible and Fourier-transform infrared spectroscopies) with online product analysis to obtain the time- and space time-resolved evolution of the entire reaction media. A ZSM-5 zeolite catalyst was tested in two commercial spectroscopic cells at 400 °C using different space times (different inlet flow rates). Specifically, our work focusses on the effect of the space time (key parameter in any kinetic study) and how to tune other parameters such as partial pressure of methanol to resolve, from the spectroscopic and gas-phase points of view, the mechanisms of reaction and deactivation. Our approach reinforces the previous interpretation of these two combined networks in the selected reaction, thus, proving that the spectro-kinetic approach is a robust methodology to simultaneously build overall reaction and deactivation mechanisms.
