Catalytic pyrolysis of wheat bran for hydrocarbons production in the presence of zeolites and noble-metals by using TGA-FTIR method

Facile Solution for Recycling Hazardous Flexible Plastic-Laminated Metal Packaging Waste To Produce Value-Added Metal Alloys

“…64 A significant peak at 2966 cm −1 is attributed to the C−H bond in the aromatic ring, corresponding to the hydrocarbons. 65 From 2600 to 2000 cm −1 , the strong peak at 2357 cm −1 corresponds to the asymmetric OCO functional groups of carbon dioxide (CO 2 ). 66 The absorption peak from 2000 to 1000 cm −1 is comprised of several peaks which are due to the C−H bending of the aromatic hydrocarbon, CO stretching, CC stretching of the functional group, and C−H bending vibrations in the methylene group with the symmetry axis of carbon.…”

Hydrogen purification using natural zeolite‐loaded hydroxyethyl cellulose membrane

“…The second decomposition occurs between the temperature of 310 and 345 C. This is due to the degradation of hemicellulose and cellulose in the structure of HEC. 42,48 In the second decomposition temperature of HEC, there is an increase of 7 C with the addition of 10 wt% zeolite and 35 C with the addition of 20 wt% zeolite. These increases should be attributed to the higher thermal stability of the zeolite than that of HEC.…”

Enhancement of biomass conversion in catalytic fast pyrolysis by microwave-assisted formic acid pretreatment

“…While CFP can rapidly convert biomass to aromatics, its carbon efficiency has yet to be improved to make the conversion process more economically competitive (Lazdovica et al, 2016;Li et al, 2013Li et al, , 2015Widayatno et al, 2015). It is well-known that natural lignocellulosic biomass consists of three major components, i.e., cellulose (40-50 wt.%), hemicellulose (25-35 wt.%), and lignin (15-20 wt.%) (Alonso et al, 2010;Huber et al, 2006).…”
