Pyrolysis experiments were conducted at atmospheric pressure in a batch reactor ranging from room temperature until 420 °C. The suitable heating rate was studied by keeping constant the reaction temperature at several levels (300, 320, 340, 360, 380 and 400 °C) for 60 min. by application the best heating program; MgO and Al₂O₃ additives are examined at various proportions (1, 2, 3, 4 and 5% by weight). It has been shown that the addition of MgO (1-2% by wt.) leads to a supplemental improvements in the DLF quality where the properties are the closet to those of conventional diesel fuel.

The aim of this study is to purify industrial textile effluents by treating two types of commonly encountered dyes: blue maxilon (BM), of cationic nature, and black eriochrome (NE), of anionic nature. We intend to employ an innovative approach based on the adsorption of these dyes onto a novel vegetal biomaterial derived from Aleppo pine fibers (FPAs). A kinetic and thermodynamic study was conducted. The effect of some physicochemical parameters on both dye adsorption and FPAs was also evaluated. The modeling of the adsorption results was performed using Langmuir, Freundlich, Temkin, and Dubinin Radushkevich (D-R) isotherms. The results indicate that the equilibrium time strongly depends on the initial concentration of the two dyes, being 60 min with pseudo-second-order adsorption kinetics for both dyes. Adsorption isotherms under the optimal conditions of adsorbent mass, temperature, medium pH, and dye concentration were used to determine the maximum adsorption efficiency, which was close to 93% and 98% for BM and NE, respectively. The results also show that the adsorption of both dyes on FPAs fits well with Langmuir’s model. The thermodynamic study indicates that the adsorption of both dyes on FPAs is spontaneous and exothermic in nature for BM and endothermic for NE.

The city of Taza, situated in Morocco, boasts a significant ecological heritage. However, a concerning practice of discharging untreated wastewater into the nearby Oueds has raised apprehensions about potential threats to public well-being. This research endeavors to discern the locations most...

The needles of the Aleppo pine (Pinus halepensis) (PA) are very abundant in the forest of the National Park of Tazekka (Taza-Morocco) and are unexploitable. Moreover, they constitute a potential danger because they facilitate the outbreak of wildfires. To solve this problem, we have considered...

The olive mill waste water, effluents from the trituration of olives, are treated in most Mediterranean countries by natural evaporation. However, this method of treatment is a source of air and soil pollution by the generation of a solid waste, called olive mill waste cake. This work focused...
