Exploring Influence of MgO/Na2O on Melting Characteristics and Viscosity–Temperature Characteristics of Coal Slags Under Entrained Flow Gasification Condition

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Characteristics of high alkali in Zhundong coal ash may cause ash‐related slag discharge problems at entrained‐flow‐bed (EFB) gasifier. In this study, through exploring melting characteristics and viscosity–temperature characteristics, it is found that MN05, MN14, and MN23 show low FTs (< 1160°C).

High-Temperature Oxidation of Magnesium- and Iron-Rich Olivine under a CO₂ Atmosphere: Implications for Venus

Remote Sensing, 2023
Understanding crust–atmosphere interactions on Venus is fundamentally important to interpretations of Venus’ surface spectroscopic data. Olivine, in basaltic crust, is oxidized under a heated CO2 atmosphere.

Granular Bed Filtration of Coal Pyrolysis Gas: Effects of Media Reactivity on Dust Removal and Products

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Granular bed filtration is a promising technology for removing dust from high‐temperature coal pyrolysis gas. In this work, the reactivity of coal pyrolysis products over ceramsite, char, ultrastable Y‐type (USY) zeolite, and quartz particles was compared.

ECO: A new reference model of dry olivine electrical conductivity

Solid Earth Sciences
Electrically Conductive Olivine, ECO, is presented as a new reference model for the electrical conductivity of dry olivine. The model takes into account the prevailing redox state, temperature and pressure in the upper mantle, as well as their effects on

Potential contribution of biomass gasification‐based technology in energy transition: a technical review coupled with bibliometric studies

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biomass gasification technology has been extensively researched around the world; however, there is a need to evaluate the current research landscape and evolutionary direction of research in the broader context of energy transition. A systematic bibliometric analysis of the Web of Science database was performed for articles that fall within ...

Catholyte‐Free Composite Cathodes Break the Energy Density Barrier of All‐Solid‐State Lithium Batteries

Carbon Energy, EarlyView.
All‐solid‐state lithium batteries (ASSLBs) with conventional catholyte‐based composite cathodes have a theoretical energy density limit of approximately 400 Wh kg–1 and 900 Wh L–1. The design of catholyte‐free composite cathodes can break this barrier and improve the theoretical energy density up to 500 Wh kg–1 and 1000 Wh L–1. ABSTRACT The gravimetric

Signal to Noise Ratio and Spectral Sampling Constraints on Olivine Detection and Compositional Determination in the Intermediate Infrared Region: Applications in Planetary Sciences

Earth and Space Science
Spectral features of olivine across the intermediate infrared region (IMIR, 4–8 μm) shift systematically with iron‐magnesium content, enabling determination of olivine composition.

Laboratory-scale model of carbon dioxide deposition for soil stabilisation

Journal of Rock Mechanics and Geotechnical Engineering, 2016
Olivine sand is a natural mineral, which, when added to soil, can improve the soil's mechanical properties while also sequester carbon dioxide (CO2) from the surrounding environment.
