The effect of crystallinity on selectivity of palladium catalysts in hydrogenation of 2-ethyl-9,10-anthraquinone

The catalytic properties of palladium crystallites obtained from various precursors were studied in the hydrogenation of 2-ethyl-9,10-anthraquinone. The highest yield of H2O2 (88percent) is achieved on unmodified Pd crystallites obtained from Pd(dba)2 at 50°C. A sigmoidal relationship between the coherent domain size (CDS) of Pd particles and the content of anthrones, which are by-products of the eAQ transformation, is established. Small Pd clusters, along with the reduction of eAQ carbonyl groups, accelerate predominantly the hydrogenation of the eAQH2 aromatic rings. The smallest contribution of the side processes is observed for a palladium catalyst with a CDS of 3–5 nm.

Mesoporous silica-supported Ni-B amorphous alloy catalysts for selective hydrogenation of 2-ethylanthraquinone

The effects of pore structure on the reaction rates and selectivities in the liquid-phase hydrogenation of 2-ethylanthraquinone over Ni-B amorphous alloy catalysts prepared by the reductant-impregnation method were studied using regular (HMS, MCM-41, and

Hydrogenation of 2-ethylanthraquinone over Pd/poly(4-vinylpyridyne) catalysts

Polymer, namely poly(4-vinylpyridyne) (PVP) was used as a support for palladium catalysts acting in liquid phase hydrogenation of 2-ethylanthraquinone (eAQ), a key step in industrial production of hydrogen peroxide. The catalytic hydrogenation was carried out in a slurry reactor at atmospheric pressure of H2 and temperature 43°C. The progress of eAQ hydrogenation over Pd/PVP catalyst was the same as observed earlier in the presence of Pd/SiO2. In initial stage of reaction eAQ was reduced with high selectivity to eAQH2 (2-ethylanthrahydroquinone). In the further process termed "deep hydrogenation" hydrogenation of aromatic rings (formation of tetrahydroanthrahydroquinone H4eAQH2) and hydrogenolysis of carbon-oxygen bonds (formation of degradation products) in eAQH2 proceeded. It was stated that in the presence of mass transport limitations the progress of reactions leading to the formation of "degradation products" was intensive.
