New discoveries in chemical research and development in 2021.In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. In an article, author is Zhou, Chunbao, once mentioned the application of 56353-15-2, Name is (S)-2-(3-Acetamidopropanamido)-3-(1H-imidazol-4-yl)propanoic acid, molecular formula is C11H16N4O4, molecular weight is 268.27, MDL number is MFCD04039376, category is pyrrolines. Now introduce a scientific discovery about this category, Category: pyrrolines.
Co-pyrolysis of textile dyeing sludge and red wood waste in a continuously operated auger reactor under microwave irradiation
The eco-friendly disposal of textile dyeing sludge (TDS) has become a worldwide environmental issue due to their complexity and toxicity. In this study, co-pyrolysis of TDS and red wood waste (RWW) in a continuously operated auger reactor under microwave irradiation was investigated, which was more environmentally friendly and created higher value added products. Effects of pyrolysis temperature and RWW ratio were studied to evaluate product distribution and properties. Increase of temperature and RWW ratio resulted in decrease in char yield and increase in gas yield. The contents of CO, CH4, and H-2 increased significantly with RWW ratio increased at 650 degrees C. The content of pyridines, amines, and nitriles enhanced sharply with increasing temperature from 450 to 750 degrees C. Co-pyrolysis promoted the Maillard reaction and cracking of nitrogen-containing pigments, forming large quantities of N-heterocyclics in bio-oil. Sludge char obtained by pyrolysis of TDS at 650 degrees C had a greater sulfur retention ability than chars from co-pyrolysis. The highest methylene blue number (372.25 mg/g) and iodine adsorption value (332.42 mg/g) were achieved from TDS and biochar (750 degrees C, 30 wt% RWW ratio), respectively. Fe(III) in Fe2O3 was reduced to Fe(II) in Fe3O4 and further partially reduced to metallic Fe in biochar. (C) 2020 Elsevier Ltd. All rights reserved.
