CO 2 hydrogenation over Fe catalysts to short-chain hydrocarbons, which can be used to adjust the heating value of substitute natural gas, is investigated as example reaction. A specific reactor design for flexible operation with gas recycling is a consequence of the constraints resulting from ...
Here, using furfural as an example, we reveal the important role of water-mediated protonation in a typical hydrogenation reaction over a supported Pd catalyst. Depending on the solvent, we have observed different reaction orders with respect to the partial pressure of H, as well as distinct ...
Thus, initial reaction rate, selectivity and maximum yield can be evaluated. In a similar way, the optimization of the kinetic pa- rameters of benzene hydrogenation (Eqs. (3)–(5)) has been carried out searching minims of the SR function and the results are exposed, for example, in ...
more precise nanolithography technique, and investigated the hydrogen spillover effects on TiO2and Al2O3supports7. But no reaction (not possible for such structure) is conducted to verify the proposed hydrogen spillover mechanism under the real reaction conditions. Therefore, well-defined bicomponent c...
10 This Piers type hydrosilylation is the first example of FLP chemistry, and has attracted intensive interests.11 However, the asymmetric reaction is still not well-solved. This Letter will therefore outline the present progress of metal-free catalytic asymmetric hydrogenation and hydrosilylation using...
Cu-ZnO–Al2O3 catalysts, industrially used as the catalysts for the important water gas shift (WGS) reaction (CO + H2O → CO2 + H2)7 and CO hydrogenation to methanol reaction (CO + 2H2 → CH3OH)8,9, are a representative example. This has inspired great efforts...

Example II 70 grams of benzoic acid and 15 grams of the reduced and stabilized copper-alumina catalyst described in Example I were placed in a steel autoclave to which hydrogen was added to 100 atmospheres initial pressure, and the reaction mixture was then heated to 300* C. for four hours...
The hydrogen-bearing feed material suitable as a feed stock for the present invention may be any hydrogen-bearing feed material capable of undergoing a hydrogenation reaction, including, but not limited to, a biomass, for example, forestry products or by products, crop residue, animal waste, ...
Preparation Example Synthesis of Scaled-Up MOF-808 ZrOCl2.8H2O (13.5 g, 0.04 mol) and 1,3,5-benzenetricarboxylic acid (9.3 g, 0.04 mol) were dissolved in a mixed solution of DMF/formic acid (164 ml/160 ml) to prepare a reaction mixture. The reaction mixture was agitated at room temper...
