Efficient Conversion of Rapeseed Cake into Bio-Alcohol Through Pyrolysis

Abstract

Pyrolysis of biomass is a promising technology of bio-chemicals’ production. In this study, pyrolysis of rapeseed cake to produce valuable bio-alcohols has been carried out in an integrated pyrolysis-gas chromatograph/mass spectrometry system (Py-GC/MS). The physicochemical properties were determined by ASTM methods, elemental analysis and FT-IR spectroscopy. Physicochemical analysis results showed that rapeseed cake has high volatile matter content which is suitable for the pyrolysis process. According to the pyrolysis experiment results, various valuable bio-alcohols are present in the degradation products at 10 min pyrolysis time. All the results would help further perceive thermal decomposition and thermo-chemical application for bio-alcohols and of rapeseed cake. © 2021, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG.
