Online mass spectrometric analysis of sulfur compounds from hydrothermal reactions of biomass wastes for hydrogen production

Abstract

Biomass/biowaste gasification using supercritical water is a new way to produce hydrogen gas, a clean and renewable energy. This method besides producing hydrogen will also produce heteroatomic compounds, substances that can be a burden to the environment; therefore, it is important to clarify the mechanisms of these compounds. A newly developed online mass spectrometry determination of the sulfur compounds released during hydrothermal reaction from l-cysteine as model compound and durian fruit as practical sample was done. The effect of alkaline Ca(OH)2 addition on the formation of sulfur heteroatom compounds has been studied in detail.
