Dataset of Biochar Fertilizer Preparation via Biogas Residue Pyrolysis and Quality Regulation focuses on the resource utilization of biogas residue, a byproduct of anaerobic fermentation. It conducts experiments and analytical tests for studies on the effects of anaerobic fermentation inoculants and fermentation degrees on the carbonization of biogas residue through pyrolysis. The dataset mainly records data including: thermogravimetric analysis, pyrolysis kinetics, thermogravimetry-Fourier transform infrared spectroscopy-mass spectrometry (TGA-FTIR-MS) analysis of biogas residues from dry anaerobic digestion with different biomass and fermentation inoculants; char yield and pH value of biogas residues under different dry anaerobic digestion degrees; ultimate analysis (C, H, O, N), proximate analysis (moisture, volatile matter, fixed carbon and ash), X-ray diffraction (XRD) analysis of both biogas residues and the biochar derived from them; thermogravimetric pyrolysis characteristics and volatile release characteristics analysis (via TGA-FTIR coupling) and Fourier transform infrared spectroscopy (FTIR) surface functional group analysis of biogas residues; as well as the migration and transformation characteristics of NPK nutrient elements (organic nitrogen, inorganic nitrogen, ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, inorganic phosphorus, available potassium, slow-release potassium, etc.) during the straw dry anaerobic digestion - biogas residue pyrolysis process.
