... The characteristics of biochar produced from the co-pyrolysis of corn stalk (CS) and mulch film (MF) were analyzed. Cellulose, hemicellulose, lignin were applied to explore the synergistic effects of CS and MF during co-pyrolysis. Upon increasing the proportion of MF, the yield of liquid products increased, and the yield of solid products decreased. Interactions of cellulose, hemicelluloses, and li ...

Abstract:
... Oil pollution is causing deleterious damage to aquatic ecosystems and human health. The utilization of agricultural waste such as corn stalk (CS) to produce biosorbents has been considered an ecofriendly and efficient approach for removing oil. However, most previous studies focused on the modification of the whole CS, which is inefficient due to the heterogeneity of CS. In this study, corn stalk ...

Abstract:
... A corn stalk cellulose-based adsorbent with bifunctional groups of -NH−/-NH₂ and C-S/C=S for efficient removal of Cu²⁺ and Pb²⁺ was successfully synthesized. Under specific alkali and reaction conditions, 4.58 mmol/g of C-S/C=S groups were further introduced on surface of aminated cellulose with 6.99 mmol/g of amino groups. The introduced CS₂ would only participate in the esterification with -NH₂ ...

Abstract:
... Liquefaction of high solid loadings of unpretreated corn stover pellets has been demonstrated with rheology of the resulting slurries enabling mixing and movement within biorefinery bioreactors. However, some forms of pelleted stover do not readily liquefy, so it is important to screen out lots of unsuitable pellets before processing is initiated. This work reports a laboratory assay that rapidly ...

Abstract:
... Fenton pretreatment is known as a green and mild approach, but it is usually time-consuming and inefficient in promoting lignocellulose enzymatic hydrolysis. Here we demonstrate that thioglycolic acid (TA) significantly accelerates Fenton pretreatment (FP) of corn stover (CS) and improves enzymatic hydrolysis of cellulose and xylan. The results showed that the reducing sugar yield of CS reached 77 ...

Abstract:
... Three locally available biomasses namely bagasse, corn stalk and leaves (CSL) and coconut shell (CS) were subjected to torrefaction in this study. Three parameters were varied namely temperature residence time and particles sizes to determine the optimum torrefaction conditions. The enhancement factor which is a ratio between the GCV of torrefied biomass to GCV of untorrefied biomass was found to ...

Abstract:
... With appropriate pretreament, sugars can be a major product from fast pyrolysis of lignocellulosic biomass. Analytical pyrolysis of pure cellulose can produce up to 60 wt% yield of levoglucosan although yields are significantly lower in continuouos pyrolysis at larger scales. Secondary reactions of vaporized levoglucosan are thought to be responsible for this loss of sugar yield, suggesting change ...

Abstract:
... Asian corn borer, Ostrinia furnacalis (Guenée), is an important insect pest of maize throughout most of Asia. The rind of a maize stalk is a key barrier against corn borer larvae boring into the plant. There is a need to better understand the relationship between stalk strength and O. furnacalis larval injury, particularly for elite maize genotypes. To determine whether stalk strength is involved ...

Abstract:
... Saccharification of cellulose into glucose is a key step for the utilization of lignocellulose. Molten salt hydrate (MSH) is unique in selective hydrolysis of cellulose into glucose but the separation of formed glucose from MSH is challenging due to the high solubility of glucose in MSH. To address this issue, this work developed a method where a small dosage of MSH was applied to impregnate cellu ...

Abstract:
... Mono-cationic ionic liquids (MILs) have been widely utilized for the treatment of lignocelluloses. However, the hydrophilic property of MILs increases the difficulty of isolating sugars and their reuse, which limits their industrial application. In the present study, a series of dicationic ionic liquids (DILs) were synthesized with totally different di-cations and di-anions. An alternating miscibi ...
