摘要：Citric acid-modified hydrochar was prepared via the hydrothermal carbonization of pomelo peel (PP) at different temperatures (180-240 degrees C), and deeply explored in this paper. Based on the results, pomelo peel hydrochar prepared at 220 degrees C and 240 degrees C (PPH220-CA/PPH240-CA) were characterized by superior energy yield and HHV contents, with relatively low residual ash contents of 1.09% and 1.48%, respectively, hence were selected for cocombustion with coal. The 70%PPH220-CA/30%coal blend showed superior combustibility with an S value of 4.79 x 10. Interestingly, a synergistic effect between PPH220-CA and coal was detected during the cocombustion process, and the interaction strengthened with an increase in PPH220-CA proportion. Analysis of gas emissions via TG-IR revealed that small amounts of H, CO, C = O, phenols, C-O and plentiful CO2 emissions were produced in the combustion process. Hence, the addition of PPH220-CA into fuel blends of coal can significantly reduce CO emissions and alleviate the greenhouse effect.
