TL;DR: In this paper, a benign environmental catalyst for the generation of biodiesel is an area of importance to reduce the overall usage of fossil fuels, where biochar was used to prepare solid acid catalysts by sulfonation process.

TL;DR: In this paper, a dual fuel burner designed for co-firing of waste-derived solid fuels (e.g., biomass, refused-derived fuel, sewage sludge) with pulverized coal in practical combustors was evaluated through trials undertaken in a 0.5 MW down-fired furnace.

TL;DR: Results showed that sawdust conditioning in conjunction with cationic polyacrylamide (CPAM) presented much better dewaterability than CPAM alone when used as a filter aid for the textile dyeing sludge dewatering.

TL;DR: In this paper, the organic composition of a paper mill sludge (PMS) mixture was investigated during composting to better understand the changes in main chemical components, such as lipids, sterols, lignin, N-compounds, and carbohydrates.

TL;DR: In this article, an Activated Carbon (AC) was prepared from sapelli wood sawdust using a microwave heating process and the biomass was mixed with inorganic components (lime + ZnCl2 and FeCl3) to form a homogeneous paste.
Abstract: Activated carbon (AC) was prepared from sapelli wood sawdust using a microwave heating process. The biomass was mixed with inorganic components (lime + ZnCl2 and FeCl3) to form a homogeneous paste. The AC samples are denoted as AC-1A (100 g sapelli wood sawdust + 20 g lime + 80 g ZnCl2), AC-2A (150 g sapelli wood sawdust + 20 g lime + 80 g ZnCl2), AC-1B (100 g sapelli wood sawdust + 20 g lime + 40 g ZnCl2 + 40 g FeCl3), and AC-2B (150 g sapelli wood sawdust + 20 g lime + 40 g ZnCl2 + 40 g FeCl3). The samples were placed in a microwave oven and pyrolyzed under nitrogen flow. To increase their porosity, the pyrolyzed samples were subjected to a leaching process (with 6 mol L−1 HCl) under reflux to eliminate inorganic components. Several analytical techniques such as Fourier-transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and N2 isotherm and vapor adsorption analyses were performed to characterize the AC materials. The samples presented high Brunauer–Emmett–Teller (BET) surface areas, up to 941.08 m2 g−1 for AC-1A. The AC materials were tested for their o-cresol removal ability by determining the best fits to equilibrium and kinetic data using the Sips isotherm and fractional-order model, respectively. The maximum adsorption capacity of the AC samples as obtained from the Sips model was correlated with the surface area. The proposed adsorption mechanism suggests that hydrogen bonding, donor–acceptor complexation, and π–π interactions play key roles. The adsorbents were also tested for treatment of simulated industrial effluents, showing very good efficiency. Almost complete regeneration of the AC adsorbents was achieved using 10 % EtOH + 5 mol L−1 NaOH as eluent. These results demonstrate that sapelli wood sawdust is a promising precursor for preparation of AC to remove o-cresol from aqueous solution.
