Effect of syngas recirculation in the pyrolysis zone on the rice husk gasification process using the downdraft reactor

Case Studies in Thermal Engineering
As one of the world's largest rice producers, Indonesia has an abundance of rice husk as a byproduct of rice milling. Rice husks were utilized to examine downdraft gasification with syngas recirculation system.

Emerging Materials and Future Strategies for Solid Oxide Electrochemical Cells

Advanced Energy Materials, EarlyView.
Solid oxide electrochemical cells operate under strongly coupled electrochemical and thermodynamic conditions, where performance is constrained by interactions among crystal structure, defect chemistry, and interfacial evolution. This review, based on a structure‐defect‐property‐durability framework, reveals the roles of lattice symmetry and defect ...

Challenges and enablers in fluidization technology

AIChE Journal, EarlyView.
Abstract Gas–solid fluidized beds provide excellent heat and mass transfer for high‐throughput operations from coating to catalytic conversion and underpin emerging low‐carbon technologies. Yet industrial reliability, scale‐up, and control lag scientific understanding, particularly as finer, stickier, and more variable feedstocks increasingly challenge

Perimeter‐intensified inverse Zr‐Co oxygen carrier for biomass chemical‐looping gasification with high CO selectivity

AIChE Journal, EarlyView.
Abstract Chemical‐looping gasification (CLG) offers a promising route for renewable biomass valorization, yet conventional oxygen carrier regeneration with O₂/H₂O is energy‐intensive and often produces low‐quality syngas. Here, we develop an inverse ZrO2/Co3O4 oxygen carrier that enables selective biochar oxidation and efficient lattice‐oxygen transfer

Automated generative process synthesis via transformer‐based dual‐loop simulation and optimization

AIChE Journal, EarlyView.
Abstract This study presents a novel framework for automated generative process synthesis, addressing the complexity of simultaneously optimizing discrete topologies and continuous operating variables. To overcome conventional superstructure limitations, we propose a dual‐loop architecture integrating generative transformers with rigorous process ...

MODELLING AND SIMULATION OF FUELS PRODUCTION FROM SYNGAS

Studia Universitatis Babes-Bolyai Chemia, 2017
Syngas is a very important product, with a variety of uses; it may even become a primary source of fuel, and replace natural gas. This is because syngas has the building blocks to create all the products and chemicals currently generated in the ...

Risk assessment of syngas pipeline leakage based on a Dynamic Bayesian Network

Emergency Management Science and Technology
The syngas pipeline serves as the primary carrier for syngas exported from the coal gasification furnace, is vulnerable to corrosion and erosion from the transported medium, and is prone to leakage due to long-term high-pressure operation.

A Carbon‐Induced Surface Reconstruction on an Operating Fischer–Tropsch Catalyst

Angewandte Chemie International Edition, EarlyView.
It is widely believed that a cobalt Fischer–Tropsch catalyst initially undergoes an activity‐enhancing roughening, driven by the high chemical potential of carbon. In this operando STM and DFT study, we simulate such conditions. We show that, instead, a triangular stacking‐fault reconstruction may form, leaving the catalytic activity unchanged ...
