“…The method of deashing by HCl–HF washing has been described elsewhere. 28 The carboxyl groups on the surface of CM were removed by esterification, and the adsorption ability of the modified CM was experimentally determined to deduce the effect of the surface carboxyl groups during adsorption. The esterification of the dried biomass was carried out according to a method described elsewhere.…”

Biochar is a low cost and renewable adsorbent which can be used to remove dye from wastewater. Cattle manure-derived low temperature biochar (CMB) was studied to remove methylene blue (MB) from aqueous solution in this paper. The effect of factors including initial concentration of MB, dosage, contact time, and pH on the adsorption properties of MB onto biochar were studied. Characterization of the CMB and MB adsorbed on CMB was performed using techniques including BET, FTIR and SEM. The adsorption isotherm, kinetics, thermodynamics and mechanism were also studied. The results showed the equilibrium data were well fitted to the Langmuir isotherm model, and the saturation adsorption capacity of CMB 200 was 241.99 mg g À1 . Pseudo-second order kinetics was the most suitable model for describing the adsorption of MB onto biochar. The adsorption thermodynamics of MB on biochar showed that the adsorption was a spontaneous and endothermic process. Through zeta potential measurement, Boehm titration, cation exchange, deashing and esterification experiments, the importance of ash to adsorption was verified, as well as the adsorption mechanism. The adsorption mechanism of MB on CMB 200 involved cation exchange, electrostatic interaction, hydrogen bonding, physical effects and others. This work shows that CMB 200 holds promise to act as an effective adsorbent to remove MB in wastewater.

“…Due to a high water content and ash content, and low heating value for livestock and poultry manure, direct combustion is prone to instability (Dávalos et al 2002). Alkali and alkaline earth metal (AAEM) species in cattle manures exert both positive and negative effects on combustion (Yi et al 2018a). Co-firing with pulverized coal can reduce the combustion instability, improve the combustion reactivity, and decrease the phenomenon of fouling and slag (Kim et al 2015;Yurdakul 2016;Junga et al 2017).…”

“…Thermogravimetry (TG) is the most common method for analyzing the combustion characteristics of fuel (Cheng et al 2014;Yi et al 2014;Yurdakul 2016;Yi et al 2018a, b). A slight difference between isothermal and non-isothermal combustion has been observed in previous studies (Chen et al 2015).…”

Combustion characteristics of cattle manure (CM) and pulverized coal blends under oxy-fuel atmosphere were considered. Factors such as the furnace temperature, O2 concentration, and blending ratio were analyzed. The experiment under non-isothermal and isothermal conditions were used to study effects of the heating rate. Blended CM can improve the combustion characteristics of pulverized coal. However, a difference exists between the increase of the blending ratio of CM with Shanxi bituminous coal (SX) and Xiaolongtan lignite coal (XLT) under various O2 concentration conditions. More attention should be paid to the blending ratio > 50%. CM and coal co-firing affected by the furnace temperature had a close association with its characteristics. Inhibition was found in most conditions, and the trend of interaction between CM and coal under the non-isothermal and isothermal condition was consistent. These experiments provided information for the utilization of livestock and poultry manure and pulverized coal blends in the oxy-fuel atmosphere.

Effect of alkali and alkaline earth metal species on the combustion characteristics of cattle manures

Abstract: This study investigates the effects of alkali and alkaline earth metal (AAEM) species on the combustion characteristics of cattle manures (CM). Different AAEM species (K, Na, Ca, and Mg) were mixed with CM and deashing CM (D-CM) samples.
