TGA–FTIR analysis of co-combustion characteristics of paper sludge and oil-palm solid wastes

Pyrolysis behaviors and kinetic studies on Eucalyptus residues using thermogravimetric analysis

“…In a TGA experiment, the pyrolysis behaviors (mass loss and mass loss rate) can be measured as functions of temperature and time in an inert atmosphere [7]. By using the TGA data, many mathematical methods such as model-fit and model-free http were widely used in corresponding studies [8][9][10]. However, these methods are limited to use in biomass pyrolytic kinetics investigation due to the high heterogeneous (such as catalysis of alkalis and secondary reactions) of the pyrolysis process [11,12].…”

THE USE OF COMPRESSED FLUIDS TO OBTAIN BIOCOMPOSITES FROM PALM OIL FIBER (Elaeis sp.)

“…Above 340 ºC up to the final temperature the mass loss happens slowly. In this temperature range the loss was close to 25% of the total mass, and can be attributed to the degradation of the remaining holocellulose and lignin (Lin et al, 2015). The high ash content (7.6%), allied to charcoal formation, contributes to a lesser total mass loss.…”

“…The most significant mass loss was observed between 225 and 340 ºC, as evidenced by the DTG curve, being approximately 35%. This loss can be related to holocellulose degradation (Lin et al, 2015). However, a bigger mass loss was expected in this temperature range, because the holocellulose content in the sample is close to 50%, but it should be emphasized that other factors, such as cellulose crystallinity, may influence the degradation process (Hassan et al, 2013).…”

Thermogravimetric analysis of the co-combustion of eucalyptus residues and paper mill sludge

“…1 showed that it was very easy to distinguish between the different phases the combustion process of PMS. As reaction temperature rose, the process of PMS could be divided into two individual stages, which was almost same as the TGA-FTIR analysis of co-combustion characteristics of paper sludge and oilpalm solid wastes [25]. The first stage was from 272.83 to 588.10°C.…”

“…The index S was a comprehensive combustion parameter. The larger the index S was, the more vigorously the samples burned and the faster char burned out [25]. The index S values of ER, PMS and their blends were presented in Table 2.…”
