The catalytic fast copyrolysis (CFCP) of cork oak (CoOak) and waste plastic films (WPFs) over HBeta(25) (SiO2/Al2O3: 25) was investigated using a thermogravimetric (TG) analyzer and a tandem micro reactor-gas chromatography/mass spectrometry (TMR-GC/MS) to determine the effectiveness of WPFs as the hydrogen donating cofeeding feedstock on the CFCP of biomass. By applying CFCP, the maximum decomposition temperatures of CoOak (373.4 °C) and WPFs (487.9 °C) were reduced to 364.5 °C for CoOak and 436.5 °C for WPFs due to the effective interaction between the pyrolysis intermediates of CoOak and WPFs over HBeta(25), which has strong acidity and an appropriate pore size. The experimental yields of aromatic hydrocarbons on the CFCP of CoOak and WPFs were higher than their calculated yields concluded from the yields obtained from the individual catalytic fast pyrolysis (CFP) of CoOak and WPFs. The coke amount produced from the CFP of CoOak and WPFs over HBeta(25) were also decreased by applying CFCP.

“…The quality loss caused by the thermal degradation and volatilization of cork components is roughly consistent with the results of existing research. The thermal stability temperature of cork is lower than 200°C, at which the material begins to experience mass loss (Lee et al, 2018). Material degradation and volatilization strengthen with the increase in temperature.…”

How to achieve a balance between energy conversion and CO2 emission in biomass materials is one of the urgent problems to be solved. Inspired by diatoms, a simple method was used to deposit silica aerogel mineralized layer in cork cells. The thermal decomposition behavior and products of four kinds of corks CS-P (cork of Quercus suber)、CV-P (cork of Quercus variabilis B1)、CSS-P (cork of Quercus suber deposited with silica aerogels) and CSV-P (cork of Quercus variabilis B1 deposited with silica aerogels)were systematically studied, and the carbon capture of silica aerogel in cork and the production mechanism of high-value products during pyrolysis were deeply studied. Interestingly, this method has dual effects. In the pyrolysis process, the existence of silica aerogel significantly reduces the emissions of CO2 and aldehyde, while the output of aromatic hydrocarbons and other products with added value is significantly increased. This work provides a novel and effective method to convert and manage biological waste resources to achieve environmental sustainability and carbon neutrality.

The co‐pyrolysis behavior of low‐grade coal with two different feedstocks (beeswax and petroleum wax) at different compositions (w/w) [(75:25), (50:50), (25:75)] is investigated by using a thermogravimetric (TG) analyzer under the non‐isothermal condition at a constant heating rate of 20°C/min from an ambient temperature to 900°C under nitrogen atmosphere. The kinetic and thermodynamic analysis for the thermal decomposition of the sample parameters was carried out by applying the model fitting Coats–Redfern method to the thermogravimetry data of different feedstocks. The activation energy of thermal degradation of coal is found to be 55.8 kJ/mole. A decrease in activation energy is observed by the addition of 25% and 50% waxes in the blended sample and the blended sample with 25% wax and 75% coal has the lowest activation energy. The activation energy for coal‐beeswax blend (75:25) is 35.718 KJ/mol, but it is 34.237 KJ/mol for coal‐petroleum wax blend (75:25). The value of ∆H decreases by the addition of waxes and follows the order (Coal: Feedstock) {(75:25) < (50:50) < (25:75)}, while that of value of ∆S increases by the addition of waxes and follows the order {(75:25) > (50:50) > (25:75)}. However, the value of ΔG does not significantly shift as the blend ratio of the feedstocks is altered. The addition of both feedstocks with the coal sample showed some degree of synergy. The result illustrates that the co‐pyrolysis of coal with wax be energy economical than individual pyrolysis and this study would give precious scope to design a more efficient conversion system.
