Journal ArticleDOI
Depolymerization of lignocellulosic biomass to fuel precursors: maximizing carbon efficiency by combining hydrolysis with pyrolysis
Jungho Jae,Geoffrey A. Tompsett,Yu Chuan Lin,Torren R. Carlson,Jiacheng Shen,Taiying Zhang,Bin Yang,Charles E. Wyman,W. Curtis Conner,George W. Huber +9 more
TL;DR: In this article, the carbon efficiency of combining hydrolysis and pyrolysis processes using maple wood as a feedstock was studied, and three possible options for the integration of hydropolymerization with pyro-probe processes were evaluated based on their material and carbon balances.
Journal ArticleDOI
Hydrochloric acid-catalyzed levulinic acid formation from cellulose: data and kinetic model to maximize yields
Jiacheng Shen,Charles E. Wyman +1 more
TL;DR: In this paper, the kinetics of the acid catalyzed hydrolysis of microcrystalline cellulose (Avicel PH101) to levulinic (LA) and formic (FA) acids was investigated in a batch reactor over the following range of conditions: 160-200°C, hydrochloric acid concentrations of 0309-0927 M (113-338 g/l), cellulose concentrations of 498-149 mM (806-241 g /l), and residence times of 0-50 min.
Journal ArticleDOI
A novel mechanism and kinetic model to explain enhanced xylose yields from dilute sulfuric acid compared to hydrothermal pretreatment of corn stover.
Jiacheng Shen,Charles E. Wyman +1 more
TL;DR: It is suggested that autocatalytic reactions from xylan to furfural in hydrothermal pretreatment were controlled by oligomeric xylose decomposition, while acid-catalysttic reactions in dilute acid pretreatmentwere controlled by monomericxylan decomposition.
Journal ArticleDOI
Effects of seasonal hydrological regulation of cascade dams on the functional diversity of zooplankton: Implications for the management of massive reservoirs and dams
TL;DR: In this paper , the authors examined the zooplankton functional diversity in a typical river with cascade dams and compared the differences between the upstream and downstream parts of the river during the dry and wet seasons.
Journal ArticleDOI
Damming has changed the migration process of microplastics and increased the pollution risk in the reservoirs in the Shaying River Basin.
Jiacheng Shen,X. Gu,Run Liu,Hongyu Feng,Dian-Peng Li,Yan Liu,Xufei Jiang,Ge Qin,Shuqing An,Ning Li,Xin Leng +10 more
TL;DR: In this article , the authors investigated the characteristics and abundance of microplastic (MP) pollution in water, sediment and biological tissues from samples collected in the vicinity of ten dams in the Shaying River basin and analyzed the effect of environmental and food web structural changes on MP accumulation in freshwater animals under the influence of dams.
