- Abstract
This research examined the influence of pyrolysis temperature on a large-size feedstock of coconut shell waste for producing biochar and liquid smoke using slow pyrolysis. The temperature used was varied between 250 °C to 450 °C at a constant heating rate of 10 °C/min and at a holding time of about 120 minutes. Gravimetry, spectro, and high-performance liquid chromatography (HPLC) methods are used to identify the liquid smoke for density, phenol, and acetic acid content respectively. The results indicated that increased pyrolysis temperatures caused a reduced biochar yield. However, the liquid smoke yield was found to increase with the temperature. The obtained liquid smoke has a density of 1.054 g/mL and has a content of phenol of about 4717.91 mg GAE/100 mg, and acetic acid of 11.36%. Results inferred that the liquid smoke can be generated from a large size of coconut shell through pyrolysis at medium temperature.
