Thermodynamic driving forces for autoreduction of Cu sites in the zeolite SSZ-13 React. Chem. Eng. (IF 3.9) Pub Date : 2024-03-15 Daniel Hutton, David Humberto Lopez, Florian Göltl
Cu-exchanged zeolites are widely used redox catalysts and the oxidation state of Cu is crucial in understanding their performance over a wide range of applications. Interestingly, a fraction of Cu sites in zeolites is reported to reduce at high temperatures in the absence of a reducing agent and as of today a detailed understanding of this process is still missing. In this contribution, we use first

Hydrothermal Liquefaction of Plastics: a survey of the effect of reaction conditions on the reaction efficiency. React. Chem. Eng. (IF 3.9) Pub Date : 2024-03-15 Matthijs Justin Boel, Hongqi Wang, Ahmad Al Farra, Laura Megido, José Manuel González, Raveendran N. Shiju
Plastic waste is a major global issue. Recycling has not made a big impact as hoped, most of the waste is still landfilled or incinerated. Hydrothermal liquefaction (HTL) is a promising technique for plastic recycling. In broad terms, it converts wet carbon-containing feedstocks (e.g., wet biomass or plastics) back into simpler molecules using elevated temperature and pressure. Sub- and supercritical

Recent progress on catalysts for propane dehydrogenation in presence of CO2 React. Chem. Eng. (IF 3.9) Pub Date : 2024-03-06 Kai-Xin Li, Xin Cai, Hong-Bin Liu, Xin-Yu Liu, Yuling Shan, Xiang Feng, De Chen
Propane dehydrogenation (PDH) has become an important strategy to address the ever-increasing global demand of propene. Introducing CO2 as soft oxidant for oxidative propane dehydrogenation (CO2-OPDH) not only promotes the reaction towards propene formation, but also expanding the way of converting CO2 to valuable chemicals. Moreover, the CO2 could also participate in coke removing process to retain
