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

open access: yesAsia-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 ...

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Synthesis and Application of Conductive Pitch‐Based Porous Carbon for Energy Storage Device as a Supercapacitor

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Conductive pitch‐based porous carbon materials were synthesized and systematically investigated as high‐performance electrode materials for supercapacitors. Petroleum‐derived pitch was thermally treated and chemically activated using KOH and NaOH at different pitch: activating agent molar ratio (1:1, 1:2, and 1:4) to optimize the pore ...

Potassium Migration of Chestnut Shell Ashes Under Oxidizing Atmosphere and Its Modification Mechanism by Additives

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Biomass energy plays a critical role in alleviating environmental pressures. However, its relatively high content of alkali metals (especially for potassium) would cause ash‐related issues during combustion. To mitigate these issues, the potassium migration behaviors during chestnut shell (CS) conversion and the modification mechanisms of ...

Green Fuel Combustion Synthesis of CeO2 and Ag/CeO2 Nanoparticles for Photocatalytic and Antibacterial Applications

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Silver‐doped cerium oxide nanoparticles (Ag/CeO2 NPs) were synthesized using Ricinus communis seed extract as a bio‐derived fuel in a solution combustion method. The combustion reaction, carried out at 450°C with AgNO3 and (NH4)2[Ce (NO3)6] as metal precursors, produced CeO2 and Ag/CeO2 NPs.

Metal‐CO2 Batteries: By‐Product Challenges and Practical Pathways for Low CO2 Concentration Environment

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Metal‐CO2 batteries have recently emerged as an intriguing class of energy storage and conversion devices that simultaneously utilize and manage carbon dioxide. Originating from studies of CO2 contamination in metal‐air batteries, these systems have evolved into a distinct research direction, offering insights into CO2 electrochemistry and its
