2017 DOE-Crosscut Lean/Low-Temperature Exhaust Emissions Reduction Simulation (CLEERS) Workshop

October 3–5, 2017 Ann Arbor, Michigan, USA

The 20th Crosscut Lean/Low-temperature Exhaust Emissions Reduction Simulation (CLEERS) Workshop sponsored by the US Department of Energy and organized by the Oak Ridge National Laboratory was held on October 3–5, 2017 in Ann Arbor, Michigan. The …

Development and Validation of a Two-Site Kinetic Model for NH3-SCR over Cu-SSZ-13. Part 1. Detailed Global Kinetics Development Based on Mechanistic Considerations

In this study, we present the first of two parts in the development and validation of a two-site detailed global kinetic model for NH3 Selective Catalytic Reduction (SCR) over a well-characterized Cu-SSZ-13 catalyst. Based on fundamental …

Development and Validation of a Two-Site Kinetic Model for NH3-SCR over Cu-SSZ-13—Part 2: Full-Scale Model Validation, ASC Model Development, and SCR-ASC Model Application

We present herein the final part in the development and validation of a two-site kinetic model for NH3-SCR over Cu-SSZ-13. To predict tailpipe emissions accurately, it was necessary to combine the kinetic model of the SCR catalyst developed in …

Frictional and Heat Transfer Characteristics of Flow in Triangle and Hexagon Channels of Wall-Flow Monoliths

In the 1D modeling of flow and heat/mass transfer of wall flow monoliths (WFMs), it is common to use a friction factor and Nusselt number generated from an idealized 2D/3D solution. The results are usually expressed as functions of wall Reynolds …

SO2 Oxidation Across Marine V2O5-WO3-TiO2 SCR Catalysts: a Study at Elevated Pressure for Preturbine SCR Configuration

The undesired oxidation of SO2 was studied experimentally at elevated pressures of up to 4.5 bar across two commercial vanadium-based (1.2 and 3 wt% V2O5) selective catalytic reduction (SCR) catalysts. This pressure range is of interest for …

Über diese Zeitschrift

Emission Control Science and Technology is a forum for publication of the latest research on control of emissions from mobile and stationary sources. Papers are also welcome on various aspects of development and technology. The investigation may be experimental, theoretical, or computational.

Articles must survive rigorous peer review before they are considered for publication. Examples of topics that may appear in the journal include:

  • Emission control in mobile (road, land, sea, air) and stationary (e.g. power generation, industrial processes) applications.
  • Materials for and formulations of novel substrates and catalysts, such as those used in Diesel Oxidation Catalyst (DOC), Three Way Catalysts (TWC), Diesel Particulate Filters (DPF), Selective Catalytic Reduction (SCR), Lean NOx Trap (LNT), combined catalysts (e.g. DPF+SCR or DPF+LNT in one substrate), slip catalysts, or reformer catalysts.
  • Performance of emission control system components such as sensors, injectors for fuel and reducing species, exhaust inserts and mixers, etc.
  • Effects of operational parameters (e.g. flow, temperature, species concentration) and design approaches (sizing, layout, insulation, etc) on regulated and unregulated emissions and emission control system efficiency and performance.
  • Basic and applied research on specific components (e.g. nanoparticles, N2O and other non-regulated pollutants) of emissions and their mitigation.
    System considerations such as engine-out to tailpipe efficiency, optimization, PGM management, and formation of secondary species.
  • Engines, combustion, fuels, or lubricants as they would affect emission reduction technologies or post combustion processes.
  • Testing, durability and compliance such as cycles, certification, aging, NVH, in-field (on-vehicle) performance and analysis, and in-use compliance.
    Analysis of current and future emission regulations (including those in the developing world).
  • Biological and environmental effects of emission control technologies.
