The possibilities of pistachio shell biochar production on laboratory-scale gasification and pyrolysis devices have been described by several previous studies. Nevertheless, the broader results co-gasification process pilot-scale units not yet properly investigated or reported, especially regarding detailed description acquired during routine operation. was analysed using analytical techniques, such as ultimate proximate analysis (62%wt C), acid–base properties (pH 9.52), Fourier-transform...
This study investigates the performance of DC corona discharge electrostatic precipitators (ESPs) for NO conversion to increase DeNOx technologies’ efficiency small-scale biomass combustion systems. Experiments were conducted using a 5 kW automatic wood pellet domestic heat source with gas treated in specially designed ESP operated both positive and negative modes, resulting reduction concentrations from 130 mg/m3 27/29 positive/negative polarities (at 0 °C 101.3 kPa). was evaluated across...
The environmental problems in Peru are rooted the waste management of residual agricultural biomass. Via our cooperative international research, nine different wastes from were used as renewable sources to produce activated carbons that tested gas-phase xylene adsorption. special properties agro-waste very large mesopore surface area, narrow pore size distribution within microporous–mesoporous region, and slightly acidic character presence oxygen-containing groups. textural, structural,...
In line with the requirements of circular economy, European Union’s waste management legislative changes also concern treatment sewage sludge. Although sludge production cannot be prevented, its quantities may reduced by synergetic effect energy recovery via choosing a proper technology. Sewage is difficult to apply as fuel alone, because high moisture and ash content. However, use will increased adding suitable materials (different types plastics, tires paper rejects). Most recently,...
Abstract Ashes were prepared by annealing selected types of solid fuels (biomass: corn cobs, sunflower husks, olive pomace, hay pellets and rice husks; coal: lignite bituminous; alternative fuel: paper sludge) at different temperatures (550°C, 815°C 975°C). Based on X-ray fluorescence spectra, the slagging/fouling indexes used to study effects type ash ashing temperature fouling slagging properties. Slagging compared with fusion temperatures. Ash measured a LECO AF-700. The lowest...
An electrostatic precipitator (ESP) is an efficient device for removing fly ash from small-scale solid-fuel combustion. Under corona discharge, a gaseous medium becomes ionised, and particles become charged by colliding with ions. electric field forces the movement of to remove gases induces generated ions, causing secondary electrohydrodynamic flow. Thus, particle charge, presence neighbouring particles, ESP field, gas flow turbulence can enhance coagulation. Therefore, ultrafine...
Biomass stoves are not only popular, widespread and important sources of heat but also negligible pollutants.The present study had two objectives in this field research.The first one was to determine the difference between standard wooden beech leaves briquettes flue gas composition during similar, home combustion conditions.The second objective possibility decreasing mass concentration pollutants contained produced by alternative fuel combustion, i.e. briquettes, an oxidation...
Electrostatic precipitators (ESPs) have shown promise in reducing particulate matter (PM) emissions, but their potential for simultaneous NOx reduction small-scale combustion systems remains underexplored. This study focuses on using non-thermal plasma generated a corona discharge to reduce PM and emissions from combustion. ESP was specifically designed commercially available 15 kW boiler with wood pellet used both positive negative polarity control without any chemical additives....

Abstract The sorption of xylene and isooctane was measured by the gravimetric flow method on commercial activated carbons (ACs), namely, virgin reactivated ACs. Nitrogen physisorption, high‐pressure mercury porosimetry, helium pycnometry, iodine number, pH measurement, Raman X‐ray photoelectron spectroscopies were applied for textural, structural, surface characterization equilibrium geometries molecules modeled using density functional theory (DFT) calculations. Their dimensions estimated...
