Ding studied the mechanisms of phosphate removal by Sponge iron. It is found that the results show both Freundlich and Langmuir-Freundlich can well describe the adsorption equilibrium and the pseudo-second-order model can give a good simulation for the process of phosphate adsorption on Sponge iron (Ding et al. 2010).

The results indicated that substituting hydrogen for hydrocarbon-based fuels led to a remarkable reduction in fuel and air consumption, resulting in increased …

Sponge Iron. Sponge iron, also known as direct-reduced iron (DRI), is a type of iron produced by reducing iron ore (typically in the form of pellets or lumps) using a reducing gas or solid reductant, such as coal.This reduction process occurs at a lower temperature compared to traditional iron smelting, resulting in a porous, sponge-like structure, hence …

The results showed that although the SI application prolonged the start-up time of the reactor, achieved efficient and stable nitrogen removal after a successful start-up. ... Sponge Iron (SI) is mainly composed of zero-valent iron（ZVI）, which is internally loose and porous with a large specific surface area. Given its cost-effectiveness, ...

The results show that neither the adsorption process over s-Fe 0 nor the photo-Fenton-like process over FeOOH, Fe 3 O 4 and Fe 2 O 3, achieved efficient removal of RhB. ... Industrial sponge iron (s-Fe 0) particles are usually synthesized by the direct reduction of charcoal and iron ore. Its composition mainly includes iron, carbon and a …

With rapid economic growth, steel requirement for housing, infrastructure and industry is poised to grow significantly. In 2030, more than 60 per cent of the steel produced in India will come from coal-based sponge iron. This means more than 200 MT of sponge iron and hundreds of sponge iron factories. Hence, there is an urgent need to develop ...

2. Overview of DR processes Direct reduction processes reduce iron ore (in the form of lumps, pellets or fines) to the solid state using a reducing gas to produce …

Iron sponge (iron oxidized onto wood shavings) uses a simple packed tower (3) on a flow-through support (4). After liquid separation (1), the deflected (2) sour gas flows down to contact with the reactive iron oxide, simply and effectively converting H2S into a solid. The iron sulfide stays in the packed tower, effectively removing it from the ...

Sponge Iron, also known as, direct reduced iron (DRI) is a kind of metallic product which is produced from the direct reduction of iron ore to a solid-state (iron). India became the largest producer of sponge iron in the world and accounted for ~24% of the global production in the year 2016 and apart from that India's crude steel industry ...

Phosphorus in water not only degrades water quality but also leads to a waste of resources. In this study, adsorption thermodynamics and kinetics were used to study the effect of sponge iron on phosphorus removal, and a filtration bed was used to simulate the phosphorus removal in polluted water. The results showed that the maximum theoretical …

2. Overview of DR processes Direct reduction processes reduce iron ore (in the form of lumps, pellets or fines) to the solid state using a reducing gas to produce Direct Reduced Iron (also known as sponge iron).

Sponge iron (SI) is a promising material for nitrogen removal from wastewater. This study reveals the potential functions and mechanisms of SI-mediated multiple metabolic processes in the nitrogen removal of Anammox. The results showed that although the SI application prolonged the start-up time of …

The iron oxide process (also known as the iron sponge process) is the oldest and still the most widely used batch process for sweetening natural gas and NGLs ( Duckworth and Geddes, 1965; Anerousis and Whitman, 1984; and Zapffe, 1963 ). The process was implemented during the 19th century.

To enhance the dechlorination reactivity of millimetric sponge iron (s-Fe(0)), a facile one-pot method was used to decorate s-Fe(0) with Ag(+) ions under ambient conditions. The results recorded by X-ray diffraction patterns, X-ray photoelectron spectra and high-resolution transmission electron microscopy demonstrated that the growth of …

An iron sponge is an enclosed tank or vessel that contains a bed of materials such as hydrated iron oxide and wood chips inside which remove hydrogen sulfide from "sour" natural gas and biogas streams. The iron sponge was invented and first used in Europe approximately 120 years ago for H2S removal or " gas sweetening ."
