Study on pyrolysis kinetics of walnut shell

Experimental study on fluidization behaviors of walnut shell in a fluidized bed assisted by sand particles

“…In this work, the walnut shell (WS), as a high-potential biomass energy source, was selected as biomass material, 25 and its fluidization behaviors when assisted by different-sized sands at various blending proportions were studied to provide clear insight into the gas and solid hydrodynamics of WS/sand mixtures in a cold visual fluidized bed. The fluidization characteristic curves of each bed material were compared and analyzed, and the relative difference between U mf,i and U mf,f as well as the average fluidization rate ( R f ) were employed to quantitatively evaluate the fluidization quality.…”

Thermal Degradation of Lignocellulosic Fuels: Biopolymers Contribution

“…DSC seems to be a convenient tool in order to follow the thermal degradation at the laboratory (Liodakis et al, 2002). The degradation of forest fuels begins with the pyrolysis process from 373K to 773K (Simeoni et al, 2001;Shanmukharadhya & Sudhakar, 2007;Tonbul, 2008;Yuan & Liu, 2007). Non-combustible products, such as carbon dioxide, traces of organic compounds and water vapour, are emitted between 373K and 473K.…”

The Relationship among the Structural, Cellular, and Physical Properties of Walnut Shells

“…Similarly, many tissues of the walnut besides the nut, including the husk, shell, shoots, wood, and leaves, are widely used in medicine, industry, and many other applications (Pei and Lu, 2011). The shell is usually ignored and thrown away, despite belonging to a class of highly insoluble species that can be used to produce chemicals, such as activated carbons, natural fibers, and powders, which are extensively used in the defense industry, space industry (Khantwal et al, 2016), chemical industry (Yuan and Liu, 2007), and in environmental protection (Ding et al, 2013).…”
