Journal ArticleDOI
An overview on engineering the surface area and porosity of biochar.
Lijian Leng,Qin Xiong,Lihong Yang,Hui Li,Yaoyu Zhou,Weijin Zhang,Shaojian Jiang,Hailong Li,Huajun Huang +8 more
TL;DR: It is suggested that the lignocellulosic biomass is an outstanding candidate, wood and woody biomass in particular, and moderate temperatures (400-700 °C) are suitable for the development of the pore structure.
Journal ArticleDOI
Nitrogen in bio-oil produced from hydrothermal liquefaction of biomass: A review
TL;DR: A review comprehensively summarized the effects of the type, composition, and pretreatment of biomass and HTL processing parameters, such as temperature, residence time, solid loading, reaction solvent, extraction solvent/procedure, and catalyst, on the N content of bio-oil as discussed by the authors.
Journal ArticleDOI
A review on nitrogen transformation in hydrochar during hydrothermal carbonization of biomass containing nitrogen
Lijian Leng,Lihong Yang,Songqi Leng,Weijin Zhang,Yaoyu Zhou,Haoyi Peng,Hui Li,Yingchao Hu,Shaojian Jiang,Hailong Li +9 more
TL;DR: The present review overviewed the characteristics of hydrochar and the original feedstock, the possible N transformation behavior and mechanisms, and the effect of factors such as feedstock and pyrolysis parameters such as temperature on hydrochar N to mediate the migration and transformation of N in hydrochar.
Journal ArticleDOI
Machine learning aided bio-oil production with high energy recovery and low nitrogen content from hydrothermal liquefaction of biomass with experiment verification
Jie Li,Weijin Zhang,Tonggui Liu,Lihong Yang,Hailong Li,Haoyi Peng,Shaojian Jiang,Xiaonan Wang,Lijian Leng +8 more
TL;DR: In this article, a machine learning algorithm was employed to aid the bio-oil production with the consideration of related factors in HTL, including biochemical and elemental compositions of biomass, process parameters, and solvents.
Journal ArticleDOI
Bioenergy recovery from wastewater produced by hydrothermal processing biomass: Progress, challenges, and opportunities
Lijian Leng,Weijin Zhang,Songqi Leng,Jie Chen,Lihong Yang,Hailong Li,Shaojian Jiang,Huajun Huang +7 more
TL;DR: Comprehensive analysis of AP compositions, clarification of the mechanisms ofValorization processes, valorization process integration detoxification of AP, polycultures and co-processing of AP with other waste, enhancement in pollutant removal, scaling-up performance, and the techno-economic analysis and life-cycle assessment of valorized systems are promising directions in future investigations.
