Biocoal and biocoke production from agro residues
WEBOct 1, 2023 · Biocoal typically has more elemental carbon than raw material due to the degradation of volatiles during pyrolysis. For example, biocoal obtained from oil palm trunk (OPT) pyrolyzed at 550 °C has % fixed carbon, significantly higher than % fixed carbon measured in the raw OPT [66].It can be attributed to the removal of hydrogen .
