The mitigation of carbon deposition for Ni-based catalyst in CO2 reforming of methane: A combined experimental and DFT study

Carbon Capture Science & Technology
The dry reforming of CH4 (DRM) reaction can simultaneously convert two greenhouse gases CO2 and CH4 into high valued syngas. Nickel-based catalysts have been widely studied because of the low cost and high activity.

Biotechnological aspects of sulfate reduction with methane as electron donor [PDF]

, 2010
Biological sulfate reduction can be used for the removal and recovery of oxidized sulfur compounds and metals from waste streams. However, the costs of conventional electron donors, like hydrogen and ethanol, limit the application possibilities.

Methane Pyrolysis Performance in Catalytic Molten Media for Hydrogen Production From the Perspective of Bubble Column Reactor Design and Configuration

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In the hydrogen production routes from natural gas (methane), methane pyrolysis offers a cleaner option than the established steam methane reforming by producing CO2‐free hydrogen. However, in fixed bed reactors over solid catalysts, this technology experiences rapid catalyst deactivation due to carbon (coke) deposition encapsulating its ...

High mercury emission (both forms: Hg0 and Hg2+) from the wet scrubber in a full-scale lignite-fired power plant [PDF]

, 2020
The paper describes and discusses the results of research on mercury behaviour, especially its high emission, in both forms: elemental (Hg-0) and oxidised (Hg2+) from the wet flue gas desulphurisation scrubber (WFGD) in a lignite-fired power plant ...

The Effect of Sintering Flue Gas Composition on NO Reduction in Coke

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The strategy of substituting combustion air with sintering flue gas in circulating fluidized bed (CFB) systems provides a low‐cost and highly efficient approach for the purification of sintering off‐gas. In this work, coke was employed as the reducing agent, and a high‐temperature vertical tube furnace was used to simulate the dense‐phase ...

Fabrication of oxygen-defective tungsten oxide nanorods for deep oxidative desulfurization of fuel

Petroleum Science, 2018
Owing to the increasingly serious environmental issues caused by the sulfur burnt in fuel, desulfurization has become an important topic. In this work, an amphiphilic oxygen-defective tungsten oxide was synthesized by a colloidal chemistry method.

Investigation of the Degradation of Chelate Complexes in Liquid Redox Desulfurization Processes [PDF]

, 2020
Metal complexes such as Fe‐EDTA, which are used as pseudo‐catalysts or oxygen carriers in wet oxidative desulfurization processes, are subject to a degradation mechanism that significantly influences the economics of such processes. Therefore, this study
