Abstract

ABSTRACT: Pyrolysis experiments of pine nut shells (PNSs) were carried out in a screw reactor at 300–700°C with approximately 98% energy yields. The analysis results showed that higher temperatures result in elevated heating values (HVs) of products but reduced biochar and bio-oil yields. The HVs of pyrolytic gas were remarkably influenced by proportions of CH4 and H2 . Bio-oil of PNSs consisted primarily of phenols, acids, aldehydes, ketones, furans, and aromatic hydrocarbons. Five hundred degree Celsius was considered as optimal temperature for PNS pyrolysis, and biochar was the primary product with a yield of 37.11% and better Cu 2+, Ni 2+, and Zn 2+ adsorption properties.
