    Thermal behaviour of five different date palm residues of algeria by thermogravimetric analysis
    (PRO LIGNO, 2013) Amirou, Siham; Haddadou, Imane; Zerizer, A.
    Renewable energy has become more important globally especially with the current fuel and economic crisis. Date palm biomasses are highly potential materials for energy resources. The fact that they are renewable and abundantly available are amongst the attractive reasons of employing them as the major source for renewable energy. The purpose of this research was to investigate the thermal behavior of date palm biomass in order to evaluate their usefulness for energy production. In microparticular scale, the thermogravimetric analysis (TGA) is one of the techniques used to determine the thermal properties of five different date palm residues that were studied: (date palm rachis (DPR), date palm trunk (DPT), leaf base (Petiole) (LB), fruitstalk prunings (FP) and liff (LP)). The TGA technique consists to record the lost weight during the increase in temperature from 20°C until 600°C with a 10°C/min heating rate. The thermograms presented a departure phase of free water (from room temperature to 110°C) before the degradation process of the lignocellulosic constituents. The lignin and hemicellulose play an important role on the degradation of lignocellulosic materials at the temperature under 250°C. The degradation of cellulose begins at 250°C and overlaps to that of lignin until 450°C

    Effect of calcium competition on chromium adsorption by fungi biomass
    (2006) Louhab, K.; Sahmoune, Mohamed Nasser; Addad, J.; Bar, S.
    The kinetics and thermodynamic of adsorption of a mono-solute of chromium ions and of a bi-solute of chromium and calcium ions by fungi biomass (Streptomycine rimosus) was investigated in a batch system. The experimental data were analyzed based by Langmuir isotherm and a Pseudo second order mechanism, in the both the mono-and bi-solute adsorption systems, in order to predict the rate constant of adsorption, the equilibrium capacity. The results indicate that the adsorption mechanism is described by Langmuir isotherm and a Pseudo-second-order. The equilibrium adsorption capacity and the equilibrium rate constant increased with an increase in the initial chromium concentration in both mono-and bi-solute adsorption systems. The adsorption capacity of chromium decreased with an increase in calcium concentration
