The X-ray diffraction patterns of raw material i.e., coconut shell
powder and the solid residue formed by its pyrolysis are given inshell degrades mostly cellulosic portion, therefore, two prominent
peaks (21.98, 26.42) were smeared and appeared as one broad
peak (Fig. 8A). Peak shift and appearance of some new peaks (2u) in
the amorphous region 40–65 were also observed. The diffraction
patterns of coconut shell char exhibit four prominent peaks at
26.1, 35.2, 56.6 and 62.3.
