Transformation and Mitigation of Tar and Related Secondary Pollutants during Sewage Sludge Pyrolysis

Water, Journal Year: 2024, Volume and Issue: 16(14), P. 2066 - 2066

Published: July 22, 2024

Sewage sludge has long been perceived as the bottleneck of wastewater treatment plants in China, restraining healthy development sewage for decades. In recent years, pyrolysis a promising multifunctional platform attracted increasing interest converting into valuable resources. However, generation and presence tar, one key by-products during pyrolysis, limit wide application product The efficient selective conversion tar is complicated by inherent complexity various pollutants (e.g., N-, S-, Cl-containing organic pollutants, heavy metals) products, which may either migrate or be released environment, complicating in-depth posing environmental risks. This review systematically examines transformation migration related secondary order to optimize process resource recovery. We provide an overview research progress on generation, transformation, pyrolysis; discuss potential control strategies pollution abatement; highlight importance understanding pyrolysis. Additionally, we offer insights future trends hotpots this field. aims deliver information mechanism formation, pathways corresponding strategies, thus guiding design optimization processes achieve higher efficiency selectivity, with minimal pollution.

NO Emission Characteristics of Pulverized Coal Combustion in O2/N2 and O2/H2O Atmospheres in a Drop-Tube Furnace

Materials, Journal Year: 2024, Volume and Issue: 17(20), P. 4997 - 4997

Published: Oct. 12, 2024

Oxy-steam combustion is a new oxy-fuel technology. This paper focuses on the NO emission characteristics during of SF (Shen Fu) coal in O2/N2 and O2/H2O mixtures. Experiments were performed drop-tube furnace. Combustion tests carried out atmospheres for various O2 concentrations (21%, 30%, 40%, 60%) at different temperatures (1173 K, 1273 1373 K). In addition, experiments excess oxygen ratios (λ) conducted atmospheres. The influences atmosphere, concentration, temperature, ratio emissions analyzed. results show that 21% O2/79% H2O atmosphere much lower than those N2 three considered. was because large amount decomposed reasons decomposition include selective non-catalytic reaction (SNCR) mechanism char’s important role as catalyst destruction NO, either directly or by reacting with CO H2. oxy-steam combustion, significantly increased increase concentration from 21 vol.% to 60 temperature 1173 K K. slightly impacted atmosphere.

Soot formation and laminar combustion characteristics of anisole: ReaxFF MD simulation and kinetic analysis

Carbon Neutrality, Journal Year: 2024, Volume and Issue: 3(1)

Published: Oct. 31, 2024

Abstract The application of biomass energy is one the important ways to achieve carbon neutrality and deal with global warming. study on combustion mechanism anisole, an oxygen-containing fuel, helpful for biofuel large-scale application. In this study, soot formation laminar characteristics anisole were analyzed by reactive force field molecular dynamics (ReaxFF MD) kinetic simulation, respectively. ReaxFF MD simulation studies had shown that occurred in three stages, stage 1 (0–1 ns), 2 (1–2.5 3 (2.5–6 ns). stages represented pyrolysis developmental soot, graphitization During primary mechanisms as follows: H-abstraction-C H -addition, carbon-addition-hydrogen-addition, internal ring long chain link. exhibited different morphologically behaviors: from flakes onions spheres fewer branched chains. From it can be found burning velocities increased along increase temperature, while opposite trend was pressure. sensitivity coefficient naphthalene, main precursor, revealed promotional reactions R5 (O + < = > O OH), R36 (CO OH CO H).
