In this study, the effects of carbohydrates, proteins, and lipids on the combustion and pyrolysis characteristics of hydrochar were investigated by adding pure substances during hydrothermal carbonization (HTC) of typical food waste to magnify their effects on hydrochar. The experimental results demonstrated that carbohydrates …

This paper presents a review of recent research on direct upgrading of coal/biomass volatiles into aromatics by catalytic pyrolysis and syngas by gasification with catalytic steam reforming. Coal/biomass valorization is considered an important part to fill up the depletion of modern fossil fuel resources. The catalytic pyrolysis process is a potential approach to …
