Na-LTA zeolite crystals were synthesized via hydrothermal method using aluminum scraps and industrial sodium metasilicate. The obtained hydrogel with molar composition: 3,741 Na 2 O: Al 2 O 3 :1.450 SiO 2 :175.520 H 2 O was aged at room temperature for 14 hours and heated at 80°C for 6 hours. The use of aluminum scraps provides well crystallized cubic Na-LTA zeolites with truncated edges and apexes. When H 2 O/Al 2 O 3 molar ratio was decreased: 3.741 Na 2 O: Al 2 O 3 :1.450 SiO 2 :92.50 H 2 O there is formation of an intergrowth of FAU/EMT phases contaminated with LTA zeolite after 6h of crystallization. The prolongation of the crystallization time to 48 hours leads the formation of hydoxysodalite zeolite. On the other hand, the increase of aging time to 96 hours, the crystal sizes of zeolite decrease.

“…Not all the contamination phases, such as nitrides, carbides, phosphide and sulphide, could be readily detected. AlN can be easily formed, due to the negative Gibbs energy below 283.6 K of the reaction between molten Al and atmospheric nitrogen, occurring after the removal of black dross from the melting furnace [34][35][36]. Al4C3 is formed when molten Al reacts with dispersed carbon particles.…”

Highlights• The glycerol pre-treatment method is an effective way to assist in determining minor reactive phases.• The problematic mineral phases associated with AlN could be easily identified after pretreatment.• The existence of amorphous or turbostratic graphitic carbon in black dross has been confirmed.• The FT-IR allowed the successful identification of Al4C3 presence in industrial samples of black dross.

“…Additionally, some studies were performed to recover Al, but these studies did not receive much attention as they were focused on the metallic part only, without considering the polymeric part which represents the biggest part containing a lot of toxic materials [ 12 , 13 ]. In order to recycle all fractions, Samy et al (2019) used a thermal disengagement process to transform thermally the polymer–metal packaging materials into considerably pure metal and graphitic carbon particles in presence of Argon gas followed by grinding to recycle the materials into Al particles.…”

Modeling of Metalized Food Packaging Plastics Pyrolysis Kinetics Using an Independent Parallel Reactions Kinetic Model

Recently, a pyrolysis process has been adapted as an emerging technology to convert metalized food packaging plastics waste (MFPWs) into energy products with a high economic benefit. In order to upscale this technology, the knowledge of the pyrolysis kinetic of MFPWs is needed and studying these parameters using free methods is not sufficient to describe the last stages of pyrolysis. For a better understanding of MFPWs pyrolysis kinetics, independent parallel reactions (IPR) kinetic model and its modification model (MIPR) were used in the present research to describe the kinetic parameters of MFPWs pyrolysis at different heating rates (5–30 °C min−1). The IPR and MIPR models were built according to thermogravimetric (TG)-Fourier-transform infrared spectroscopy (FTIR)-gas chromatography−mass spectrometry (GC-MS) results of three different types of MFPWs (coffee, chips, and chocolate) and their mixture. The accuracy of the developed kinetic models was evaluated by comparing the conformity of the DTG experimental results to the data calculated using IPR and MIPR models. The results showed that the dependence of the pre-exponential factor on the heating rate (as in the case of MIPR model) led to better conformity results with high predictability of kinetic parameters with an average deviation of 2.35% (with an improvement of 73%, when compared to the IPR model). Additionally, the values of activation energy and pre-exponential factor were calculated using the MIPR model and estimated at 294 kJ mol−1 and 5.77 × 1017 kJ mol−1 (for the mixed MFPW sample), respectively. Finally, GC-MS results illustrated that pentane (13.8%) and 2,4-dimethyl-1-heptene isopropylcyclobutane (44.31%) represent the main compounds in the released volatile products at the maximum decomposition temperature.
