Low‐Temperature in Situ Upgrading of Ultra‐Deep Heavy Oil Using Ni–Ce/MOF–OTf Superacid Catalysts to Enhance Energy Utilization and Sustainability

open access: yesEcoEnergy, EarlyView.
A triflate‐functionalized Ni–Ce/MOF–OTf superacid enables low‐temperature (∼140°C) in situ upgrading of ultra‐deep heavy oil. It reduces viscosity by 92.11% in 12 h, maintains activity over cycles, and delivers 90.25% recovery with a lower carbon footprint by selective bond cleavage. ABSTRACT Ultra‐deep heavy oil is an important unconventional resource,

Zeolite deactivation during hydrocarbon reactions: characterisation of coke precursors and acidity, product distribution [PDF]

open access: yes, 2008
The catalytic conversion of hydrocarbons over zeolites has been applied in large scale petroleum-refining processes. However, there is always formation and retention of heavy by-products, called coke, which causes catalyst deactivation. This deactivation

A Critical Review of Electrolytes for Sodium‐Zinc Hybrid Ion Batteries: From Liquid to Solid

open access: yesEcoEnergy, EarlyView.
This review systematically discusses the evolutionary roadmap of electrolytes from liquid to quasi‐solid and ultimately to all‐solid‐state structures for aqueous sodium‐zinc hybrid ion batteries (ASZIBs), which focuses the critical bottlenecks of uncontrolled dual‐ion transport and interfacial incompatibility, and proposes corresponding countermeasures

Phenolic Resin‐Functionalized NH2‐UiO‐66‐Containing Mixed Matrix Membranes for CO2/CH4 Separation

open access: yesEcoEnergy, EarlyView.
Phenolic resin‐functionalized small‐size RFin@NH2‐UiO‐66 nanofillers were prepared and combined with polyetherimide (PEI) matrix to construct mixed matrix membranes for effective CO2/CH4 separation. ABSTRACT For mixed matrix membranes (MMMs), the inherent structural features and composition of the embedded nanofillers play a pivotal role in governing ...
