英文摘要the lignin monomer composition of palm kernel shell (pks) was characterized using pyrolysis-gas chromatography/mass spectrometry (py-gc/ms), and the characteristics and distributions of products obtained from pks pyrolysis were investigated using py-gc/ms, gc, and a specially designed pyrolysis apparatus. the gasification reactivity of pks biochar was also characterized using thermogravimetry (tg) and raman spectroscopy. all the results were compared with those obtained from wheat straw (ws) and pine sawdust (ps). the results showed that pks lignin is primarily composed of p-hydroxyphenyl structural units, while ws and ps lignins are mainly made up of guaiacyl units. both the mass and energy yields of non-condensable gases from pks pyrolysis were lower than those obtained from ws and ps pyrolysis at 650-850 degrees c, owing to the lower volatile content (75.21%) and lack of methoxy groups in pks. compared with ws and ps, higher bio-oil productivity was observed during pks pyrolysis. phenols were the main component of pks bio-oil from pyrolysis at 500 degrees c, and the phenol content of pks bio-oil (13.49%) was higher than in ws bio-oil (1.62%) and ps bio-oil (0.55%). a higher yield of biochar (on an ash-free basis) was also obtained from pks pyrolysis. because of its greater relative degree of ordered carbon, pks biochar exhibited lower in situ reactivity during co2 or h2o gasification than ws and ps biochars. a longer residence time and addition of steam were found to be beneficial during pks biochar gasification.
