The yields of pyrolysis products
The biochar and bio-oil collected after the test were collected
and weighed to determine the yields. The non-condensable gas
yield was calculated by difference. The products yields of slow
pyrolysis at different heating rates are shown in Fig. 5. It can be
seen that the heating rate within the scope of 5–30 C/min have
important effects on bamboo products yields. With increasing
heating rate, biochar yield obviously decreases from 31.1% at
5 C/min to 22.5% at 30 C/min and bio-oil yield decreases from
39.2% at 5 C/min to 34.6% at 30 C/min, whereas non-condensable
