This is digital research data corresponding to a published manuscript in "Pilot-scale H2S and swine odor removal system using commercially available biochar" Agronomy 2021, 11, 1611. Dataset may be assessed via the included link at the Dryad data repository.Although biochars made in laboratory seem to remove H2S and odorous compounds effectively, very few studies are available for commercial biochars. This study evaluated the efficacy of a commercial biochar (CBC) for removing H2S.Methods are described in the manuscript https://www.mdpi.com/2073-4395/11/8/1611. Descriptions corresponding to each figure and table in the manuscript are placed on separate tabs to clarify abbreviations and summarize the data headings and units.The data file, Table1-4Fig3-5.xslx is an Excel spreadsheet consisting of multiple sub-tabs which are associated with Tables 1, 2, 3, and 4, Figures 3, 4, and 5.Tab “Table1” – raw data for physico-chemical characteristics of the commercial pine biochar for Table 1Tab “Table2” – raw data for laboratory absorption column variables for Table 1. For dry or humid conditions, “Dry” or “Humid” is headed for each parameter name.Tab “Table3” - analytical results for odorous volatile organic compounds for 21 days of operation for Table 3. To avoid the complexity, the single values are not repeated in the data. For the multiple raw data for influent and effluent concentrations of the organic compounds larger than the detection limits are presented in this worksheet.Tab “Table4” – raw data (RH, influent and effluent concentrations) for adsorption of H2S using the pilot biochar system for Table 4. All effluent concentrations were below detection limit and not listed.Tab “Fig 3”- raw data for observed pressure drops ratios predicted by Ergun and Classen equations, i.e.,(Ergon) /(Obs) or(Classen) /(Obs), for various gas velocities (U = 0.41, 0.025, 0.164, and 0.370 m/s) in Figure 3.Tab “Fig4” – breakthrough sorption capacity data for two different inlet concentrations (25 and 100 ppm) used for Figure 4Tab “Fig5” – raw data for daily sum of influent and effluent SCOAVs used for Figure 5
