Indirect CO2 Methanation: Hydrogenolysis of Cyclic Carbonates Catalyzed by Ru-Modified Zeolite Produces Methane and Diols

Paul Joseph Dyson, Felix Daniel Bobbink, Antoine Philippe Van Muyden, Wei-Tse Lee, Zhangjun Huang

We report a ruthenium‐modified zeolite which efficiently transforms propylene carbonate to propylene glycol and methane, under solvent‐free conditions. The catalyst achieved high product selectivity and no significant ageing effect was observed after multi ...

Santosomes as natural and efficient carriers for the improvement of phycocyanin reepithelising ability in vitro and in vivo

Davide Demurtas

New biocarriers, named santosomes, were formulated using Santolina insularis essential oil and hydrogenated phosphatidylcholine. They were modified by adding propylene glycol, a hydrophylic penetration enhancer, and loaded with phycocyanin, a protein found ...

Effect of hot spots in microstructured reactors on product distribution during quasi-instantaneous exothermic reactions

Albert Renken, John Richard Thome, Lioubov Kiwi, Thomas Maeder, Navid Borhani, Bo Jiang, Julien Haber

Background. The small characteristic sizes (in the range of 102 - 103 μm) of Microstructured reactors (MSR) lead to very high specific interfacial area which, in turn, increases heat- and mass transfer efficiency. However, for quasi instantaneous exothermi ...
