Experimental data for the publication: Measuring spatiotemporal concentration and temperature profiles in a tubular fixed-bed reactor for CO₂ methanation

This repository provides the experimental data underlying all figures in the publication “Measuring Spatiotemporal Concentration and Temperature Profiles in a Tubular Fixed-Bed Reactor for CO₂ Methanation.” The data were obtained from a profiling reactor using a nickel–alumina catalyst, with a mass spectrometer applied for gas-phase analysis, as thoroughly described in the publication. The data are organised as follows: For Experiments 1–4, steady-state and dynamic profiles are sorted separately. For the dynamic profiles, the cycle number and axial position are provided along with the corresponding gas-phase composition and temperature. From these datasets, Figures 2, 3, and 4 can be derived. The underlying data for Figure 5 are provided separately. List of experiments Exp.
