Colored cotton wastes valuation through thermal and catalytic reforming of pyrolysis vapors (Py-GC/MS)

“…The biomass showed characteristics that make it suitable for the production of bio-oil through the flash pyrolysis process, such as high HHV (17 MJ kg −1 ), higher than common biomasses, such as sugarcane bagasse (Santos et al, 2020) 13 , ash content less than 10% and volatile content similar to switchgrass 14 (Table 1 ). The heating value found was similar to other lignocellulosic biomasses, such as rice husks (17.95 MJ kg −1 ), peanut husks (20.61 MJ kg −1 ) and wheat straw (17.36 MJ kg −1 ) 15 .…”

Effect of Temperature and Pyrolysis Time in Liquid Smoke Production from Dried Water Hyacinth

“…The acidity level or pH is measured to determine the acidity of the liquid smoke. The liquid smoke produced via pyrolysis is generally acidic, with a pH value in the range of 2-4, mainly in the form of acetic acid and formic acid [16,17,18].…”

Deoxygenation of Bio‐oil from Calcium‐Rich Paper‐Mill Waste

“…Santos et al [22] reported that the bio-oil yields of sugarcane bagasse and oat hulls are improved by running the TCR system at lower reforming temperatures (500, 600, and 700°C) which reduce the enhanced cracking of organic vapors. Furthermore, TCR makes a better separation between the water phase and organic phase of the pyrolysis liquid, and this is the reason why the HHV of TCR oils are higher than fast-pyrolysis oils [23,47]. However, to determine the economic viability of the TCR process of wood and DIS, a full techno-economic evaluation is required to be done as future work.…”

“…Thermocatalytic reforming (TCR) is a technology that combines intermediate pyrolysis and high-temperature reforming of volatiles in a single processing system. The organic vapors undergo cracking and reforming, and this results in bio-oil with improved physicochemical characteristics [22,23].…”
