Cotton (Gossypium hirsutum), which is one of the most abundant crops in the world, is cultivated widely in China, the United States, and Central Asia. The cotton stalk generated with cotton cultivation is an important source of lignocellulosic biomass. In recent years, cotton stalk has received increasing attention from researchers engaged in bioconversion areas, and some high-value products, s...

The overall objective of this investigation is to develop a technology to employ biomass as substitute fuel for coal to help reduce NOx.. It was achieved by governing NOx formation kinetics through in-furnace air and fuel staged co-combustion technology. An extensive series of experimentation was carried out in a 20 kW down fired combustor to evaluate the effect of co-firing of Shea meal, Cotto...

In recent years, fungal pretreatment has received renewed attention for biorefinery of lignocellulosic feedstock. The present research was aimed to examine the biodegradation effects of three white rot fungi on cotton stalk. The results showed that three white rot fungi could degrade the lignocellulose of cotton stalk effectively at a certain degradation stage, the forming ratio of hyphal prote...

Liquefaction of waste lignocellulosic biomass is a viable technology for replacing fossil fuels and meeting sustainable development goals. In this study, bio-based epoxy resins were prepared from polyhydric-alcohol-liquefied cotton stalk by glycidyl etherification. The was liquefied in polyethylene glycol/glycerol cosolvent under H2SO4 catalysis. Epon 828 cotton-stalk-based could be cured using...

To improve the accuracy of discrete element research, physical and simulation experiments were used to calibrate cotton stalk contact parameters. Based on stalk-stalk stalk-steel mechanics, parameters measured in experiments, software was build model. In process, Plackett-Burman experiment screen three significant factors from six initial factors. The steepest determine optimal interval A secon...

This study focuses on the development and characterization of pigeon pea stalk/cotton fibers mixed with a blend ratio 50/50, 70/30, 30/70, 60/40, 100/0 waste cotton 0/100 stalk composites are equipped compression molding system. The entire composite samples tested for acoustics, thermal physical parameters as per American Society Testing Materials standard (ASTM). sound absorption coefficients ...

plug-flow digesters with periodic loading mechanism are more enthusiastic than fully mechanized digestion plants for the majority of small or medium scale farms according to the costs and operational complexities. a dual-compartment plug-flow reactor equipped with a passive heating system was designed and experimentally operated by purpose of demonstrating a simple and low cost technology for h...

Densification of biomass can address handling, transportation, and storage problems and also lend itself to an automated loading and unloading of transport vehicles and storage systems. The purpose of this study is to compare the physicochemical properties of briquettes made from different feedstocks. Feedstocks such as corn stover, switchgrass, prairie cord grass, sawdust, pigeon pea grass, an...

In this work, Qiqunahu (QQH) coal, cotton stalk, cellulose and lignin extracted from stalk were selected as raw materials to study the effects of co-pyrolysis coal stalk. Online thermogravimetric mass spectrometry (TG-MS) was used analyse loss gas release characteristics during co-pyrolysis. The results reveal that mixture can significantly enhance reactivity blends promote formation effective ...
