Photothermal CO2 Hydrogenation: Reactions, Mechanisms, and Catalyst Design

open access: yesCarbon Energy, EarlyView.
Reactions, mechanisms, and catalyst design for photothermal CO2 hydrogenation. ABSTRACT Photothermal CO2 hydrogenation has attracted extensive attention because it provides a green and sustainable approach to fuel and chemicals production. The photothermal catalyst plays a critical role in CO2 conversion through a range of reactions.

Regenerative Cu/La zeolite supported desulfurizing sorbents [PDF]

open access: yes, 1991
Efficient, regenerable sorbents for removal of H2S from fluid hydrocarbons such as diesel fuel at moderate condition comprise a porous, high surface area aluminosilicate support, suitably a synthetic zeolite, and most preferably a zeolite having a free ...

Beyond Activity: The Unified Framework of the Sabatier Principle to Guide Rational Design of Durable and Active Electrocatalysts

open access: yesCarbon Energy, EarlyView.
In this review, a unified framework of the Sabatier principle is applied to a diverse range of catalytic and electrocatalytic systems for advanced clean energy technologies, with a particular focus on the oxygen reduction reaction (ORR). This approach will guide the design and development of highly active and stable catalysts for fuel cells ...

Diffusion of Carbamazepine in Hydrophobic Zeolites: A Comparative Study Using Classical and Machine‐Learned Potentials

open access: yesChemistry – A European Journal, EarlyView.
Can hydrophobic, shape‐selective zeolites efficiently remove the persistent pharmaceutical CBZ from water? This work moves beyond the static picture of interaction energies by modeling diffusion with umbrella sampling and machine‐learned potentials. Even high intrinsic diffusion barriers can be overcome through exergonic adsorption from water, yielding

SYNTHESIS AND CHARACTERIZATION OF POLYIMIDEZEOLITE MIXED MATRIX MEMBRANE FOR BIOGAS PURIFICATION [PDF]

open access: yes, 2009
Biogas has become an attractive alternative energy source due to the limitation of energy from fossil. In this study, a new type of mixed matrix membrane (MMM) consisting of polyimide-zeolite was synthesized and characterized for biogas purification ...

Durene conversion in a methanol‐to‐jet process: Exploring conversion at 150–350°C over different acid catalysts

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Acid catalyzed conversion of durene by isomerization, disproportionation, and transalkylation is of interest to the development of a methanol‐to‐jet process to reduce the amount of durene in the kerosene. It was of interest to determine whether durene conversion could be performed at a temperature lower than 350°C.

Revisiting the synthesis of dimethyl carbonate from methanol and carbon dioxide

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The process for producing dimethyl carbonate (DMC) from carbon dioxide (CO2) and methanol is explored in this article. It provides an overview of the thermodynamics involved in DMC synthesis, discussing the challenges and potential solutions. The article highlights the reported use of catalysts and dehydrating agents to improve DMC yield and ...
