Selected annotated data results as presented in "Exceeding single-pass equilibrium with integrated absorption separation for ammonia synthesis using renewable energy – redefining the Haber-Bosch loop." This excel workbook contains the crucial but not exhaustive data for ammonia catalysts and absorbents as presented in the associated publication. This dataset is intended to be supplementary to the associated publication rather than self-contained. Fig 1d,1e,3c: This excel sheet contains the data for testing of the catalyst Ru/Cs/CeO2 with varying N2:H2 ratios. In addition to three profiles of conversion with temperature, equilibrium lines and the best fit kinetic model are included. Details of the kinetic model can be found in the associated article. Also included are the conversion profiles with temperature for several other catalysts. All catalysts were tested at 21 barg in a flow reactor where the data measurement consisted of the change of flow through the system due to reaction. Fig2c: This sheet contains the condensed data for comparison of three ammonia absorbents. The absorbents are compared in terms of the amount of ammonia removed per gram absorbent per pressure of ammonia over time. Further details of the absorbent characteristics can be found in the associated article. Fig2d: this sheet contains the performance data for the absorbent MnCl2/SiO2 at four different temperatures over time. The absorbent performance is measurement by the amount of ammonia removed per gram of absorbent. Also included in this sheet are the best fit model for absorption kinetics. Details about the kinetic model can be found in the associated article. Fig3b 1-3 to 2-1: These sheets contain the data for a combined catalyst and absorbent system in which at time zero gas flow from a catalyst bed is diverted to an absorbent bed and second catalyst bed in series. The change in flow with time is a measurement of the amount of ammonia absorbed/produced. The three sheets are divided according to the ratio of N2:H2 (1:3, 1:1, 2:1). Also included in these sheets are the model predictions when utilizing the previously determined kinetic models for catalyst and absorbent independently. Details of the experimental/kinetic methodology can be found in the associated publication.
