Basic information and high heat value of biomass raw materials

This dataset records the characteristic parameters of various biomass feedstocks and the composition and properties of their products at different pyrolysis temperatures. It covers a wide range of plant sources, such as walnut shells, soybean straw, rice husks, wheat straw, corn stalks, pine nut shells, and hazelnut shells. The dataset includes pyrolysis temperatures ranging from 200°C to 800°C, covering both low-temperature and high-temperature pyrolysis processes. The composition analysis provides the content of structural components (such as cellulose, hemicellulose, lignin, and ash), the percentage of elemental composition (carbon (C), hydrogen (H), oxygen (O), and nitrogen (N)), and the ratios of volatile matter and fixed carbon in the industrial analysis. Additionally, it includes the higher heating value (HHV) of the biochar to reflect its energy characteristics. The dataset features experimental data on purified components, facilitating comparative analysis, and includes various temperature gradients, making it suitable for studying the impact of pyrolysis temperature on biochar yield and properties. This dataset is not only applicable to machine learning models for predicting biochar yield or HHV but also useful for analyzing how input features (such as composition and temperature) affect the output. Its potential applications include biochar preparation optimization, energy conversion efficiency studies, and environmental material development.
