Abstract

Pyroligneous acid is a liquid resulting from the pyrolysis process, consisting of a combination of pyroligneous acid and the oil phase (pyrolytic oil). Pyroligneous acid, also known as liquid smoke, is obtained through the degradation of biomass via the pyrolysis process. Biomass sources are largely obtained from wood biomass waste, agricultural biomass, aquatic biomass, waste sludge, and waste from the paper industry. One of them is candlenut shells, which contain hemicellulose, cellulose, and lignin as sources for the formation of pyroligneous acid. The objective of this study is to characterize the pyroligneous acid produced from candlenut shell waste by considering the effect of pyrolysis operating temperatures with variations of 300°C, 350°C, and 400°C in the pyrolysis reactor. The research results show that the best characteristics of the pyroligneous acid produced from the pyrolysis of candlenut shells are at 400°C, including a density of 1.260 gr/ml, viscosity of 1.030 cP, heating rate of 8.35°C/min, a qualitative phenol test showing a red color, and a yield of 33.33%. Meanwhile, the best acetic acid content of 4.171% was obtained at 300°C. The higher the pyrolysis operating temperature, the better the characteristics of the obtained pyroligneous acid. The study of the characteristics of pyroligneous acid is expected to serve as a reference for further development, particularly in applications in several sectors that require this pyroligneous acid.
