Propene is used for the production of polypropene plastics, acrylonitrile, propene oxide, and many other manufactures; hydrogen is considered the most viable energy carrier for the future. Conventional reaction schemes of the direct one-step catalytic conversion of ethanol into propene include the ...
Reaction intermediates in the hydrogen-exchange reaction of propene over deuterated cationform sulfonic resin were studied by means of microwave spectroscopy. In the cases of Fe-form and Ni-form sulfonic resin, the results were explained by the process via the 2-propyl-type intermediate, while the...
(3) Since water does not poison the formation of the half-hydrogenated state, it can supply such an amount of the chemisorbed hydrogen as can produce the half-hydrogenated state on the surface. Therefore, the exchange reaction can be regarded as a part of the hydrogenation....

A multi-step process for preparing 2,3,3,3-tetrafluoro-1-propene comprising the steps of (a) contacting a starting material comprising 2-chloro-3,3,3-trifluoro-1-propene with hydrogen fluoride in the presence of activated first catalyst ... S Mukhopadhyay,BA Light,KM Fleming,... - US ...
As the need for fossil fuels increase, there is greater urgency for a more sustainable fuel source to generate energy. Fuel cells use oxygen and hydrogens gas as fuel to form water and electricity at high efficiency. However, hydrogen ga... Bethany Cook 被引量: 0发表: 2016年 ...
The introduction of Sc prevented the reduction of In2O3 to In metal during the reaction, and that of water decreased the coke formation. Both additions resulted in longer lifetimes of the catalysts. The hydrogen addition increased the conversion of acetone to propene. The reaction pathways are ...
It has been shown that the CH2CHCH2F with OH reaction takes place via a barrierless addition/elimination and hydrogen abstraction mechanism. It is revealed for the first time that the initial step for the barrierless additional process involves a pre-reactive loosely bound complex (CR1) that ...
A reaction model was developed for the epoxidation of propene oxide over gold–titania catalysts. This model involves the formation of a bidentate propoxy species on titania after the adsorption of propene, which is activated by gold. Aided by a peroxide species produced from hydrogen and oxygen ...
