In this study. wheat straw (WS) was treated using two-step synergistic techniques. which were process water recirculation (PWR) during hydrothermal carbonization (HTC) and microwave energy activation (MEA). The physicochemical properties of solid and liquid products during the process of HTC PWR were characterized. https://www.roneverhart.com/MagnaFlow-OEM-Grade-Federal-EPA-Compliant-Direct-Fit-Catalytic-Converter-51821/
