ABSTRACT Thermochemical conversion of giant reed biomass during periodic variations has been carried out in a semi‐batch tubular reactor at 550°C. This study was after the incineration along river banks. Four variations, late spring (HS‐4), summer (HS‐1), autumn (HS‐2), and winter (HS‐3) were considered to investigate effect harvest time on fuel properties, pyrolysis product distribution, non‐condensable gas characterization, bio‐oil organic phase (BOP) properties. The biomasses herein had average calorific values 18.86 ± 0.05, 19.73 19.23 0.04, 18.44 0.04 MJ/kg HS‐1, HS‐2, HS‐3, HS‐4, respectively. biomass, phase, biochar, characterized using thermogravimetric analysis (TGA), chromatography–mass spectroscopy (GCMS), Fourier transform infrared (FTIR), micro‐GC, scanning electron microscopy (SEM/EDS). isolated 125 mL separating funnel, allowing natural stratification immiscible phases. BOP yield increased from 5 11 wt% HS‐4 Higher heating (HHV) ranged 19.4 0.03 22.6 0.02 relation active growth stage senescence‐dormant phase. Physical chemical properties (TAN, density, viscosity, water content, CHNS) compound groups analyzed. produced rich phenolics for all periods. showed that are improved period. As result, should be harvested avoid releases carbon dioxide into atmosphere will also reduce occurrence artificial flooding.
