Comparison of Preparation Methods of Copper Based PGMFree Diesel-Soot Oxidation Catalysts [PDF]

, 2011
CuO-CeO2 systems have been proposed as a promising catalyst for low temperature diesel-soot oxidation. CuO-CeO2 catalysts prepared by various methods were examined for air oxidation of the soot in a semi batch tubular flow reactor. The air oxidation of

Evaluation of the PAH Content in Soot from Solid Fuels Combustion in Low Power Boilers

Energies, 2019
The emission of carbon compounds (in the form of soot) to the atmosphere has a significant impact on the environment and human health. Air pollution with combustion products, having a unique combination of physical and chemical properties, is an ...

Determination of the Soot Mass by Conductometric Soot Sensors

Procedia Engineering, 2014
AbstractSoot sensors are required for on-board diagnostics (OBD) of automotive diesel particulate filters (DPF) to detect filter failures. If installed upstream of a DPF, the “engine-out” soot emissions can be determined by conductometric soot sensors.

Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater

Chemie Ingenieur Technik, EarlyView.
This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...

Experimental methods in chemical engineering: Temperature‐programmed oxidation—TPO

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Temperature‐programmed oxidation (TPO) probes the oxidative capacity and redox properties of solid materials—catalysts, metal oxides, perovskites, and carbonaceous deposits. It identifies coke type, distribution, and reactivity. TPO instruments pass an oxidizing gas (diluted O2$$ {\mathrm{O}}_2 $$, air, or less commonly N2O$$ {\mathrm{N}}_2 ...

Separation and structural analysis of soot from typical entrained flow coal gasification fine slag

International Journal of Coal Science & Technology
Soot is a flocculent carbon nanoparticle that results the imperfect combustion of fossil fuel, and numerous studies are dedicated to the reduction of soot production to alleviate the associated environmental problems.

Protocol for Reconstituting Adaptor‐Mediated Activation of Full‐Length Kinesin‐1

Cytoskeleton, EarlyView.
ABSTRACT Kinesin‐1 is a member of the kinesin superfamily that plays an essential role in intracellular cargo transport. In the absence of cargo, Kinesin‐1 exhibits low motor activity due to autoinhibition. Multiple studies have demonstrated that adaptor proteins, which link cargos to Kinesin‐1, can activate Kinesin‐1 by releasing the autoinhibition ...

From Nature to Supply Chain: Exploring Biomimicry‐Based Pathways to Sustainability and Competitive Advantage

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Inspired by insights gleaned from biomimicry theory, this paper addresses the persistent lack of theoretically grounded research in sustainable supply chain management (SSCM) and examines how nature‐inspired biomimicry principles could enhance various dimensions of its competitiveness. This study's theoretical contribution lies in its proposal

Enhancing soot oxidation using microtextured surfaces

Scientific Reports
Biomass combustion provides energy needs for millions of people worldwide. However, soot accumulation on the combustors’ walls significantly reduces heat transfer efficiency. Herein, we demonstrate how microtextured surfaces minimize soot accumulation by
