Physicochemical characterization and pyrolysis kinetics of wood sawdust

Energy Sources, Part A: Recovery, Utilization and Environmental Effects, 2016
ABSTRACTIn this work, physicochemical characterization of wood sawdust (WSD) has been carried out and kinetics of its pyrolysis has been studied. The physiochemical properties such as proximate and ultimate analysis, lignocellulosic composition, heating value and thermal analysis of WSD have been carried out.

Wood sawdust and wood originate materials as adsorbents for heavy metal ions

European Journal of Wood and Wood Products, 2004
The abilities of different types of wood sawdust and wood originate materials for removing some toxic heavy metal ions from water were investigated. Sawdust of poplar, willow, fir, oak and black locust wood, pulp and Kraft lignin were used as adsorbents. The effects of contact time, pH, metal concentration and sawdust particle size on the removal of Cu(

Preparation of bio-composite from wood sawdust and gypsum

Industrial Crops and Products, 2015
Abstract Bio-composite which is made of wood sawdust (SW) with novel modification and gypsum is presented in this paper. Attenuated total reflectance-fourier transform infrared (ATR-FTIR) characterizations reveal that the main compositions of sawdust water extractives are tannins, acetic acid, hemicellulose, and lignin.

Resistance of Wood Chips and Sawdust to Airflow

Transactions of the ASAE, 1985
ABSTRACT AIRFLOW resistance through variable height columns of wood chips and sawdust was evaluated by means of the pressure drop across an orifice plate. Input pressure to the bottom of the column was controlled by means of a sliding gate valve or damper on the supply fan air intake.

Effect of neem wood sawdust content on properties of biodegradable thermoplastic acetylated cassava starch/neem wood sawdust composites

Starch - Stärke, 2016
Due to several important limitations for applications of thermoplastic starch (TPS), thermoplastic acetylated cassava starch (TPACS) polymer was reinforced by different contents of neem wood sawdust (SD). Thermoplastic cassava starch (TPCS)/SD composites were also prepared and reinforced by different SD contents and compared with the TPACS/SD ...

Pyrolysis and combustion characteristics and kinetics of wood sawdust and wood sawdust hydrochar

Environmental Progress & Sustainable Energy, 2019
AbstractThis study compares the pyrolysis and combustion characteristics with the kinetics of wood sawdust and its hydrochar. Wood sawdust hydrochar was obtained by the hydrothermal treatment of wood sawdust (biomass/water: 1 g/4 mL) at 220°C, where the residence time was set as 90 min. After hydrothermal carbonization, carbon content and heating value

Effect of Wood Sawdust on the Aqueous Polymerization of Methyl Methacrylate

Journal of Elastomers & Plastics, 1991
The effect of different woods such as water-treated eucalypt saw dust (E.SD), alkali-treated E.SD and untreated white pine sawdust (SD) in the presence and absence of Cu 2+ ions on the aqueous polymerization of methyl methacrylate (MMA) was studied.

Limestone dust and wood sawdust as brick material

Building and Environment, 2007
Abstract The majority of abandoned limestone powder wastes (LPW) and wood sawdust wastes (WSW) is accumulated from the countries all over the world and causes certain serious environmental problems and health hazards. This paper presents a parametric experimental study which investigates the potential use of WSW–LPW combination for producing a low ...

Modelling of pine wood sawdust thermochemical liquefaction

Biomass and Bioenergy, 2019
Abstract This work presents the study of direct liquefaction of pine sawdust. The effect of the temperature, solvent, catalyst and biomass concentration was investigated in a 100 mL reactor. The optimal operating conditions are 20% biomass, catalyst – acid p-toluenesulfonic (3%), solvent – diethylene glycol and 2-ethyl-hexanol (1:1), 160 °C and 2 h ...

Adsorption of heavy metals from electroplating wastewater by wood sawdust

Bioresource Technology, 2007
Poplar wood sawdust was examined for adsorption as a replacement for current, more expensive methods of removing copper, zinc and cadmium from electroplating wastewater. Langmuir, Freundlich, BET and competitive Langmuir (two competing ions) isotherms were fitted to experimental data and the goodness of their fit for adsorption was compared. The shapes
