    Journal of Renewable Materials, Vol.10, No.6, pp. 1555-1574, 2022, DOI:10.32604/jrm.2022.018625

    Abstract Biomass is a carbon-neutral renewable energy resource. Biochar produced from biomass pyrolysis exhibits preferable characteristics and potential for fossil fuel substitution. For time- and cost-saving, it is vital to establish predictive models to predict biochar properties. However, limited studies focused on the accurate prediction of HHV of biochar by using proximate and ultimate analysis results of various biochar. Therefore, the multi-linear regression (MLR) and the machine learning (ML) models were developed to predict the measured HHV of biochar from the experiment data of this study. In detail, 52 types of biochars were produced by pyrolysis… More >

    Phyton-International Journal of Experimental Botany, Vol.91, No.4, pp. 859-868, 2022, DOI:10.32604/phyton.2022.018396

    Abstract We conducted a pot experiment to examine the feasibility of applying a reaction-finished solution of hydrochar (HRFS) to enhance rice production in a saline soil. With this purpose, HRFS was applied (0, 10, 20, 40, 60, 80 and 100 mL/pot) and rice yield and nitrogen (N) use efficiency (NUE) were determined. HRFS application significantly (P <0.05) increased rice grain yield by 19.6%–30.0% compared to the control treatment (CKU, with N but without HRFS addition). Moreover, HRFS application promoted plant height and straw biomass of rice. Increases of rice yield were mainly achieved by increases in the number… More >

    Abstract The global consumption of p-xylene (PX) for the production of polymers has raised serious concerns about its impact on the environment. As various reports have shown the risks that PX could pose to human health, research into cost-effective remedial methods to remove PX from the environment has gained attraction. In this work, a hierarchical porous crab shell biochar (KCS) was synthesized, characterized, and evaluated for its effi- ciency to remove PX from aqueous solution. The characterizations of KCS, including the porous structure, surface functional group, phase structure, and surface morphology, were discussed by N2 adsorption-desorption, FTIR,… More > Graphic Abstract
