Abstract:

The carbon monoxide methanation has possessed huge potential as an effective method to produce synthetic natural gas (SNG). The basic requirements such as high catalytic activity at low temperatures (<500 °C) and high stability throughout all temperatures is needed for an ideal methanation catalysts. The ultimate goal of the study is to examine the influential of different metal promoters towards catalytic properties and catalytic CO methanation performance.

Abstract:

CO2 is the most significant greenhouse gas, and its catalytic conversion into value-added chemicals and fuels represents the most efficient strategy for its utilization. Thermal catalytic processes typically achieve high CO2 conversion but exhibit low selectivity. In contrast, photocatalytic processes often offer high selectivity but generally result in low CO₂ conversion. To solve this issue, we developed a thermo-photo hybrid catalytic approach for CO2 conversion. This presentation will cover the design and development of efficient catalysts for the thermal catalytic reforming of CO2 and sho

The need to mitigate the environmental footprints of refineries in a sustainable and economical way is widely accepted, yet there appears to be a lack of a unilateral pragmatic approach towards CO oxidation to CO2 among the refining community. In this work we share CO promoter design strategies that can afford a tangible and immediate CO conversion efficiency increase without a need for additional precious metal loading. The key focus is on the support material architecture that is essential to boost the CO conversion and reduce the NOx generation in the FCC unit. It was demonstrated that the

Abstract:

This study focuses on the synthesis and characterization of La0.5Sr0.5MnO3 (LSMO) perovskite nanostructures via the hydrothermal method and their catalytic performance evaluation in CO oxidation. Structural analysis using techniques like XRD, FE-SEM, FTIR, and Raman spectroscopy analysis verified the development of LSMO nanostructures exhibiting a rhombohedral phase configuration. The catalytic activity of the annealed LSMO nanostructures was assessed, demonstrating significant CO conversion efficiency attributed to structural modifications enhancing catalytic performance. These findings highl

Abstract:

Based on engine bench testing, this study investigated the effect of diesel oxidation catalytic converter (DOC) formulations on the gaseous emissions performance of diesel engines equipped with a DOC+ catalyzed diesel particulate filter (CDPF)+selective catalytic reduction (SCR) system after the treatment system. The experimental results indicate that changes in DOC formulations have no significant effect on engine fuel economy. As the precious metal loading increases and the Pt/Pd ratio decreases, the T50 for CO and HC decreases, and the low-temperature conversion rates (<300 °C) for CO an

Abstract:

Transition metal alloys have emerged as promising electrocatalysts due to their ability to modulate key parameters, such as d-band electron filling, Fermi level energy, and interatomic spacing, thereby influencing their affinity towards reaction intermediates. However, the structural stability of alloy electrocatalysts during the alkaline hydrogen evolution reaction (HER) remains a subject of debate. In this study, we systematically investigated the structural evolution and catalytic activity of the c-Co/Co3Mo electrocatalyst under alkaline HER conditions. Our findings reveal that the Co3Mo al

It was established that the type of pretreatment do not have a substantial effect on the catalytic activity. The presence of O2 in the feed leads to a high conversion of CO to CO2 but no NO conversion was registered. Both NO and CO conversion was increased adding H2 to the feed.

To reveal the behaviour of such systems, a series with different potassium loadings and a fixed second metal loading of 5 wt.% was prepared.

This article introduces the initial research results on the catalytic role of tungstate and carbonate in green decontamination (TDX-2) on the conversion process of 2-chloroethyl phenyl sulfide (CEPS is a simulant of the yperite). The result shows that, under the conditions of investigation, the catalytic ability of K₂WO₄ is about 240 times greater than that of K₂CO₃. In TDX-2, K₂WO₄ catalytically reacts about 7 times faster than K₂CO₃. The K₂WO₄ catalyst in the decontamination mixture is stable, highly durable, and less likely to cause unwanted H₂O₂ decomposition. After 18 hours of mixing, it

In this study, we present the results of lignin and fuel oil conversion to hydrogen, synthesis gas, and liquid hydrocarbons in the presence of nano-sized cobalt-containing systems in a microwave-assisted plasma catalytic process. The deposition of a small amount of cobalt on lignin increases its microwave absorption capacity and provides plasma generation in the reaction zone. The role of Co-containing particles in the above catalytic reactions is probably to activate the carbon bonds of lignin, which substantially increases the microwave absorption capacity of the system as a whole.
