Summary Torrefied biomass is a commercial fuel, which is particularly produced from woody biomass via torrefaction and alternative to coal to reduce greenhouse gas emissions in the short term. In this study, torrefaction conditions of cotton stalk were optimised, and the effect of bulk density together with temperature and residence time on process yields and characterisation of torrefied cotton stalk was investigated. Response surface methodology using Box‐Behnken design was employed for the design of experiments and optimization. Cotton stalk was torrefied at a temperature between 260°C and 320°C, in 10, 35, and 60 minutes with bulk density of 125, 150, and 175 kgm−3. Temperature was the most effective parameter for the six responses (higher heating value, carbon content, hydrogen/carbon and oxygen/carbon ratios, mass loss, and energy yield). Besides, temperature/bulk density interaction was found to be significant for all responses whereas residence time/bulk density interaction was effective for process yields. The optimization results showed that more economical torrefied biomass with similar quality of lignite could also be produced under process conditions of 305°C‐32 minutes‐158 kgm−3. At this point, higher heating value and carbon content of product were calculated as 19.7 MJ kg−1 and 64%, respectively.

“…In this context, amongst the several advanced treatments proposed in the literature, adsorption is considered to be an interesting option due its versatility, efficiency, non-generation of transformation by-products and easiness of implementation when compared with other advanced treatments (Gupta and Saleh, 2013;Margot et al, 2013;Nam et al, 2014;Yu et al ., 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 4 expensive and have with high regeneration costs. These drawbacks have motivated the search for alternative adsorbents, including materials produced from agricultural and industrial wastes (Bhatnagar and Sillanpää, 2010;Calisto et al, 2015;Fernandez et al, 2015;Ferreira et al, 2015;Ioannidou and Zabaniotou, 2007;Mohan et al, 2014). Such an option also constitutes a new route for the management and economic valorization of these residues, simultaneously offering starting materials at low or no cost, which is the main concept behind circular economy (European Comission, 2014).…”

This work describes the adsorptive removal of three widely consumed psychiatric pharmaceuticals (carbamazepine, paroxetine and oxazepam) from ultrapure water. Two different adsorbents were used: a commercial activated carbon and a non-activated waste-based carbon (PS800-150-HCl), produced by pyrolysis of primary paper mill sludge. These adsorbents were used in single, binary and ternary batch experiments in order to determine the adsorption kinetics and equilibrium isotherms of the considered pharmaceuticals. For the three drugs and both carbons, the equilibrium was quickly attained (with maximum equilibrium times of 15 and 120 min for the waste-based and the commercial carbons, respectively) even in binary and ternary systems. Single component equilibrium data were adequately described by the Langmuir model, with the commercial carbon registering higher maximum adsorption capacities (between 272 ± 10 and 493 ± 12 μmol g) than PS800-150-HCl (between 64 ± 2 and 74 ± 1 μmol g). Multi-component equilibrium data were also best fitted by the single component Langmuir isotherm, followed by the Langmuir competitive model. Overall, competitive effects did not largely affect the performance of both adsorbents. Binary and ternary systems maintained fast kinetics, the individual maximum adsorption capacities were not lower than half of the single component systems and both carbons presented improved total adsorption capacities for multi-component solutions.

Thermal valorization of organic wastes by coprocessing with coal may be a management option for such wastes. In this work, the separate pyrolysis of coal and primary and secondary pulp mill sludge was assessed by thermogravimetric (TG) analysis. Then, under the same experimental conditions, the pyrolysis TG curves of the coal blends with a 10 mass% of either primary or secondary pulp mill sludge were obtained. The corresponding differential thermogravimetry curves made evident that the devolatilization of coal starts at higher temperature and reaches higher char yields than that of primary or secondary paper mill sludge. Under blending, lower devolatilization temperatures and char yields, close to the weighted calculated ones, are observed. Non-isothermal kinetic analysis showed that the Arrhenius activation energy (E) corresponding to the pyrolysis of coal was lower than that corresponding to either L1 or L2. Moreover, lower E than the weighted calculated ones was determined for the co-pyrolysis of the blends.
