英文摘要	Hydrothermal carbonization (HTC) coupled with gasification is recognized as an effective approach to produce hydrogen-rich syngas from biowastes, but only a few studies concerning the gasification capacity of various biowaste-derived hydrochars have been published yet. In this work, three types of biowaste (i.e., lignocellulosic, non-lignocellulosic and ash-rich types) were selected for the HTC experiments, and the subsequent gasification of hydrochars was carried out to investigate its thermogravimetric curves and the properties of products (i.e., syngas, tar and biochar). The results found that HTC improves the gasification efficiency in terms of the syngas quality and the conversion degree of sample. The concentrations of H-2 and CH4 in syngas were increased, while the gasified tar from hydrochars was concurrently reduced to half of its original value from biowastes under similar conditions. Furthermore, as HTC progressed, the gasification period and dynamic kinetics of samples exhibited slightly different, but the variation in the conversion process of gasification was similar; biowaste diversity in components is the reason for the former, while the developed aromatic structures in hydrochars is the explanation for the latter. These findings can not only provide a comprehensive knowledge on the gasification conversion of hydrochar, but also give a referential observation for designing, optimizing as well as scaling up the thermochemical conversion of industrial biowastes.
