  Thermal energy transport is of great importance in lignocellulose pyrolysis
for bio-fuels. The thermophysical properties of lignocellulose significantly
affect the overall properties of bio-composites and the related thermal
transport. In this work, cell-scale lignocellulose (mono-layer plant cells) is
prepared to characterize their thermal properties from room temperature down to
41 K. The thermal conductivities of cell-scale lignocellulose along different
directions show a little anisotropy due to the cell structure anisotropy. It is
found that with temperature going down, the volumetric specific heat of the
lignocellulose shows a slower decreasing trend against temperature than that of
microcrystalline cellulose, and its value is always higher than that of
microcrystalline cellulose. The thermal conductivity of lignocellulose
decreases with temperature from 243 K to 317 K due to increasing phonon-phonon
scatterings. From 41 K to 243 K, the thermal conductivity rises with
temperature and its change mainly depends on the heat capacity's change.
