Three-Phase Catalytic Hydrogenation of a Functionalized Alkyne: Mass Transfer and Kinetic Studies with in Situ Hydrogen Monitoring

Albert Renken, Lioubov Kiwi, Martin Grasemann

Systematic studies of mass transfer interactions with intrinsic reaction kinetics were performed for the threephase selective hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE) over a modified Pd/CaC

Novel catalytic applications of carbon nanofibers on sintered metal fibers filters as structured supports

Marina Ruta

Supported metal catalysts are important from both an industrial and a scientific point of view. They are used, amongst others, in large-scale processes such as catalytic reforming, hydrotreating, polymerization reactions and hydrogenations. Often, these ca ...

Hydrogen production from formic acid

Paul Joseph Dyson, Gabor Laurenczy, Céline Fellay

The present invention relates to a method of producing hydrogen gas and carbon dioxide in a catalytic reaction from formic acid, said reaction being conducted in an aqueous solution over a wide temperature range and already at room temperature (25 DEG C). ...

A viable hydrogen-storage system based on selective formic acid decomposition with a ruthenium catalyst

Paul Joseph Dyson, Gabor Laurenczy, Céline Fellay

The use of formic acid as a hydrogen-storage material has become more feasible thanks to the development of a homogeneous catalytic system of ruthenium water-soluble complexes (Ru/TPPTS; TPPTS=meta-trisulfonated triphenylphosphine) that selectively decompo ...

Carbon dioxide hydrogenation on Ni(110)

Alfonso Baldereschi

We demonstrate that the key step for the reaction of CO2 with hydrogen on Ni(110) is a change of the activated molecule coordination to the metal surface. At 90 K, CO2 is negatively charged and chemically bonded via the carbon atom. When the temperature is ...
