Experimental dataset of the reverse water-gas shift reaction in a fixed-bed reactor setup under varying reactor conditions
Year: 2026
Type: data-paper
Abstract: This data article presents a dataset of miniplant-scale reverse water-gas shift (rWGS) experiments conducted in a heated fixed-bed reactor under systematically varied operating conditions. The dataset contains processed measurements including reactor temperature, molar fractions of CO 2 , CO, H 2 , and derived quantities such as CO 2 conversion and CO selectivity. The experiments cover a wide parameter space, including gas hourly space velocities of 8000, 14000 and 20000 h -1 with temperatures between 550 and 950°C (increment of 100 K), and H 2 :CO 2 feed ratios of 2:1, 2.5:1 and 3:1. The dataset presents the steady-state values and links to the reproductible data processing step, based on a prior study, enabling Fairness of all steps from the initial measurements to the final processed variables. The processing workflow includes calibration of gas analysis signals, smoothing, dry-gas calculation, and uncertainty estimation. These data provide value for validating mechanistic kinetic models, benchmarking computational fluid dynamics (CFD) reactor simulations, training machine learning models including physics-informed machine learning frameworks, and supporting thermodynamic model assessments. All raw and processed data are made publicly available in a long-term repository, ensuring FAIR access and enabling reuse by the scientific community.
