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).

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.

STUDIES ON PERFORMANCE OF AIR ENTRAINED CONCRETE INFLUENCED BY THE VARIATIONS OF CEMENT CONTENTS, THE WATER CEMENT RATIO AND THE AMOUNT OF ENTRAINED AIR

Transactions of the Japan Society of Civil Engineers, 1957
The measurements on heat of hydration and the observations of hydration process by microscopic picture have clarified the following points: the concrete with large water cement ratio (w/c) promoted the hydration up to the age 91 days, having a small increase of strength while the one with small water Cement ratio (w/c) contained a lot of unhydrated ...

Hybrid Inertial–Centrifugal Gas–Liquid Separator: CFD‐Driven Optimization Using Coupled Discrete Phase and Wall‐Film Modeling With Response Surface Methodology

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Efficient removal of liquid aerosols from compressed gas streams is essential in chemical and energy processes. Conventional separators relying on a single mechanism (inertial or centrifugal) struggle to capture both fine and coarse droplets simultaneously.

Genetic Diversity, Adaptation, Wild Introgression, and Coat Color Mutation of Golden Yak

Animal Research and One Health, EarlyView.
Genetic diversity, adaptation, wild introgression, and coat color mutation of golden yak from two populations on the Qinghai‐Xizang Plateau. ABSTRACT The golden yak lives on the Qinghai‐Xizang Plateau with a golden coat and adapts to high altitudes and strong ultraviolet environment. The golden coat is a prominent phenotype in many domesticated species,

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 ...

Entrainment characteristics of fine particles under high speed airflow

EPJ Web of Conferences, 2017
Fine silicon particles (mean size of 2.7 μm) are used as entrained materials, and the entrainment characteristics of fine particles are investigated in a cylindrical fluidized-bed (inner diameter of 28 mm and height of 1000 mm) under high speed airflow ...

Scaffolding a Low‐Cost Experiential Bioreactor Module: Reducing Cognitive Load to Enhance Competency and Self‐Efficacy

Biochemistry and Molecular Biology Education, EarlyView.
ABSTRACT Low‐cost experiential modules are critical for democratizing biotechnology education, yet most undergraduates lack hands‐on experience with continuous‐culture bioreactor operations, which are fundamental to industrial bioprocessing. This study employed design‐based research across two iterative cycles (Fall 2024, n = 8; Fall 2025, n = 11) to ...
