SSZ‐13 Zeolite with Isolated Co2+ Sites as an Efficient and Durable Catalyst System for Non‐Oxidative Ethane Dehydrogenation

Angewandte Chemie International Edition, EarlyView.
Catalysts with the isolated Co2+ species in the 6MR (Co2+─Z2) and 8MR ([Co(OH)]+─Z) windows of the SSZ‐13 zeolite were synthesized for non‐oxidative ethane dehydrogenation to ethene. The Co2+─Z2 species demonstrate an unexpectedly high rate of ethene formation in comparison with the ([Co(OH)]+─Z species.

Hydrogen‐Enriched Microbial Oil Biodiesel With Hybrid Nanoparticles Impact on Diesel Engine Efficiency and Emissions

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study examines a dual‐fuel enhancement strategy that combines hydrogen enrichment with hybrid nanoparticle (HNP) doping. The aim is to improve combustion, performance, and emission characteristics of microbial oil biodiesel (MOB) in compression ignition engines.

Modeling, Analysis, and Experimental Testing of a Selective Catalytic Reduction Dosing System

IEEE Access, 2017
In recent years, selective catalytic reduction (SCR) system has been used in modern ship or vehicle diesel engines to reduce emissions. SCR technique is a key enabler for NOx reduction, which is critical for the performance and fuel economy of both ship ...

Time-Frequency Dynamics of Biofuels-Fuels-Food System

, 2012
For the first time, we apply the wavelet coherence methodology on biofuels (ethanol and biodiesel) and a wide range of related commodities (gasoline, diesel, crude oil, corn, wheat, soybeans, sugarcane and rapeseed oil).

Study on the Synergistic Effects and Optimization of Flotation Reagent Blends Under Low Reagent Consumption

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Under low reagent dosage, the flotation performance of diesel as a collector was enhanced, and the synergistic mechanism of diesel blended with oleic acid and CTAB was investigated. Results showed that compared to pure diesel, the oleic acid blended system (Blend A) increased clean coal yield by 81.52% to 92.24%, while the CTAB blended system (

Vitamin C‐Assisted Synthesis of Novel Cu‐SSZ‐13 Zeolite and Its High‐Efficiency Performance in Diesel Vehicle NOx Exhaust Purification

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Diesel vehicle‐derived NOx is a major pollutant, and NH3‐SCR with Cu‐SSZ‐13 is the mainstream abatement technology. In this study, vitamin C (Vc) was used as a crystal growth regulator to successfully synthesize Cu‐SSZ‐13‐Vc0.3 via the hydrothermal method. Experimental results demonstrate that the introduction of Vc significantly optimizes the

Influence of diesel surrogates on the behavior of simplified spray models [PDF]

, 2012
Numerous experimental investigations make use of diesel surrogates to make the computational time reasonable. In the few studies where measured (surrogate and real diesel) and computed (surrogate only) results have been compared, the selection ...
