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

Asia-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 ...

Wide Angle X-ray Sky Monitoring for Corroborating non-Electromagnetic Cosmic Transients

, 2010
Gravitational waves (GW) can be emitted from coalescing neutron star (NS) and black hole-neutron star (BH-NS) binaries, which are thought to be the sources of short hard gamma ray bursts (SHBs).

Effect of Temperature and Atmosphere on Agglomeration of Bed Particles in a Bubbling Fluidised Bed Burning Na‐Enriched Coal

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Agglomeration of bed materials during circulating fluidised bed (CFB) combustion or gasification of high‐alkali fuel is a practical challenge in industrial practice. This work investigates experimentally the effect of temperatures (700°C–900°C) and atmosphere (air equivalence ratios 1.61–0.53) on agglomeration in a lab‐scale bubbling fluidised

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

Asia-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 ...

Progress in all‐dry‐processed inorganic perovskite solar cells

Bulletin of the Korean Chemical Society, EarlyView.
This review summarizes recent advances in all‐inorganic perovskite solar cells, focusing on vacuum‐based deposition strategies for Cs‐based inorganic perovskite absorbers and inorganic charge transporting materials. We highlight the key principles governing inorganic film growth and future directions toward high‐performance all‐dry‐processed inorganic ...

Wurtzite‐Chalcopyrite Crystal Polymorphism in CuGaS2 Nanoparticles Dictates the Localized Surface Plasmon Resonance

Chemistry – A European Journal, EarlyView.
Crystal phase‐ and size‐selective synthesis of chalcopyrite and wurtzite‐type CuGaS2 NPs was successfully achieved. They exhibited clear LSPR in the NIR region. The extinction coefficient of chalcopyrite was three times higher than that of wurtzite due to its greater symmetry and dipole moment. These results will enable precise control of the plasmonic

Hydroprocessing of synthetic kerosene over a non‐sulphided Ni/Al2O3 catalyst: Impact of alcohols and ketones on alkene conversion

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Synthetic jet fuel containing non‐petroleum‐derived kerosene can be produced from synthetic kerosene obtained through processes that include a hydroprocessing step. The potential use of non‐sulphided (reduced) nickel supported on alumina (Ni/Al2O3) was evaluated as an alternative to sulphided catalysts to saturate alkenes in sulphur‐free ...
