Modelling of soot formation in laminar diffusion flames using a comprehensive CFD-PBE model with detailed gas-phase chemistry [PDF]

, 2016
A discretised population balance equation (PBE) is coupled with an in-house computational fluid dynamics (CFD) code in order to model soot formation in laminar diffusion flames. The unsteady Navier–Stokes, species and enthalpy transport equations and the

A Mechanochemical Kolbe–Schmitt Reaction: Catechol Carboxylation Provides Building Blocks for Renewable Plasticizers

Angewandte Chemie, EarlyView.
A mechanochemical Kolbe–Schmitt reaction of disodium catecholate enables the synthesis of mono‐ and dicarboxylated catechols at low temperature and CO2 pressure. Directly derivatizing the resulting carboxylic acid and phenolic moieties in the obtained mixture provides plasticizer blends with efficiencies competitive to commercial benchmarks.

Effects of dimethyl ether on soot formation in premixed laminar flame by laser induced incandescence method

Journal of Traffic and Transportation Engineering (English ed. Online), 2020
The control of PM emission is a rather complicated problem to be solved both for diesel engine and GDI engines. There are vast factors affecting PM emission, the fuel, A/F, combustion temperature and so on.

Oxygen driven soot formation

Proceedings of the Combustion Institute, 2017
Abstract The emission standards of combustion have been steadily reduced in recent years, and a large research effort has been focused on lowering the emissions of hydrocarbons and particulate matter. Addition of oxygenates to fuel reduces these pollutants.

A Review of Recent Research Results on Soot: The Formation of a Kind of Carbon-Based Material in Flames

Frontiers in Materials, 2021
As a product generated from incomplete combustion, soot is harmful to people’s health and the environment. In recent decades, much attention has been paid to the control of soot generation in combustion systems. Efforts to reduce soot emissions depend on

Diesel soot photooxidation enhances the heterogeneous formation of H2SO4

Nature Communications, 2022
Both field observation and experimental simulation have implied that black carbon or soot plays a remarkable role in the catalytic oxidation of SO2 for the formation of atmospheric sulfate.

Soot formation analysis of OME (oxymethylene dimethyl ether) using fuel decomposition model by molecular dynamics simulation

Nihon Kikai Gakkai ronbunshu
Oxymethylene dimethyl ether (OME) is a promising carbon neutral fuel for reducing well-to-wheel CO2 emission and expected to suppress soot formation due to the lack of C-C bond.
