KAUST team seeks improved catalysts for Lebedev ethanol-to-butadiene process for renewable rubber

Green Car Congress

A 2017 analysis by a Ukrainian/French team (Kyriienko et al. The method involves combining solid catalyst precursors in water under continuous mixing. suggested that the Lebedev method holds more potential than the Ostromisslensky. However, improved wet-kneaded catalysts have mainly been discovered by trial and error. Larina, Sergiy O.

Toshiba’s new large-scale production technology for electrolysis electrodes cuts iridium use to 1/10

Green Car Congress

P2G uses electrolysis of water to convert renewable energy into hydrogen, for storage and transportation to where it is needed. Polymer Electrolyte Membrane (PEM) electrolysis is seen as a highly promising conversion method, as it is reacts rapidly to power fluctuations and is highly durable.

UC Santa Barbara team develops catalytic molten metals for direct conversion of methane to hydrogen without forming CO2

Green Car Congress

Bi 0.73 ) achieved 95% methane conversion at 1065°C in a 1.1-meter Under these conditions, the equilibrium conversion is 98%. When the temperature was reduced to 1040 °C, the CH 4 conversion decreased to 86%. Higher conversions, at higher temperatures, were not possible because of Mg evaporation. —Upham et al.

New plasma synthesis process for one-step conversion of CO2 and methane into higher value fuel and chemicals

Green Car Congress

Instead of using H 2 , direct conversion of CO 2 with CH 4 (dry reforming of methane, DRM) to liquid fuels and chemicals (e.g. Moreover, it is a cheap carbon source which can increase the atom utilization of CO 2 hydrogenation due to the stoichiometric ratio of C and O atoms, as well as reducing the formation of water. …

NREL shows graded catalytic-protective layer boosts longevity of high-efficiency photocathodes for renewable hydrogen

Green Car Congress

Researchers at the US Department of Energy’s National Renewable Energy Laboratory (NREL) have developed a method which boosts the longevity of high-efficiency photocathodes in photoelectrochemical water-splitting devices. A PEC cell absorbs sunlight and converts that energy into hydrogen and oxygen by splitting water molecules.
