Abstract:
This work deals with the preliminary quality control of the recycled lignocellulosic wastes (biomass) and adoption of techniques to enhance their adsorptivity, under laboratory and field-simulated conditions. More specifically, deals with the selection/adaptation of models for biomass thermochemical modification and hydrocarbons adsorption/desorption. Various kinds of adsorbents were produced by thermochemical treatment, whereas (i) the thermodynamic (Arrhenius equation) and (ii) the 1st (Lagergren model), 2nd (Ho-Mckay model) and .th order kinetic parameter values were identified for the simulation of the adsorption/desorption process. The models used herein for the adsorption isotherms were: Freundlich, Langmuir, Sips etc. The Freundlich isotherm model was used in combination with the Bohart-Adams adsorption column model (as modified by Clark with the introduction of the generalized non-symmetrical logistic function), for the design of a series of continuous adsorption columns. Water adsorbency, diesel adsorbency and crude oil adsorbency were defined for various conditions of the thermochemical treatment.
