| 520 | |a Abstract Approaches to selecting alumina supports for the production of crust-selective hydrogenation Pd catalysts with a view to improving their quality are discussed. The effect of calcination temperature on the mechanophysical and textural properties of a support and the dependence of the main parameters of catalyst quality (service life, activity, and selectivity) on the heat treatment conditions of supports were studied. It was found that the calcination of low-temperature alumina at 800°C allows us to obtain the optimum ratio of the strength and textural properties of a support for use in the synthesis of selective hydrogenation catalysts. The basic requirements for alumina used as a support are: It must have high mechanical crushing strength (more than 4 N/$ mm^{2} $). The strength of the material must be uniform; the content of granules with a strength of less than 40 N/$ mm^{2} $ in a support batch must be no greater than 5%. Losses due to attrition in aqueous and hydrocarbon environments must be no greater than 1.5 wt %. The mode of heat treatment for a support must contribute to the stability of texture characteristics during oxidative regeneration (450–500°C). | ||

The effect of calcination temperature on the mechanophysical and textural properties of a support and the dependence of the main parameters of catalyst quality (service life, activity, and selectivity) on the heat treatment conditions of supports were studied. It was found that the calcination of low-temperature alumina at 800°C allows us to obtain the optimum ratio of the strength and textural properties of a support for use in the synthesis of selective hydrogenation catalysts. The basic requirements for alumina used as a support are: It must have high mechanical crushing strength (more than 4 N/$ mm^{2} $). The strength of the material must be uniform; the content of granules with a strength of less than 40 N/$ mm^{2} $ in a support batch must be no greater than 5%. Losses due to attrition in aqueous and hydrocarbon environments must be no greater than 1.5 wt %.

The effect of calcination temperature on the mechanophysical and textural properties of a support and the dependence of the main parameters of catalyst quality (service life, activity, and selectivity) on the heat treatment conditions of supports were studied. It was found that the calcination of low-temperature alumina at 800°C allows us to obtain the optimum ratio of the strength and textural properties of a support for use in the synthesis of selective hydrogenation catalysts. The basic requirements for alumina used as a support are: It must have high mechanical crushing strength (more than 4 N/$ mm^{2} $). The strength of the material must be uniform; the content of granules with a strength of less than 40 N/$ mm^{2} $ in a support batch must be no greater than 5%. Losses due to attrition in aqueous and hydrocarbon environments must be no greater than 1.5 wt %. The mode of heat treatment for a support must contribute to the stability of texture characteristics during oxidative regeneration (450–500°C).</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Aleshin, A.

Selecting heat treatment conditions of alumina supports to improve the quality of selective hydrogenation palladium catalysts |
| abstract |
Abstract Approaches to selecting alumina supports for the production of crust-selective hydrogenation Pd catalysts with a view to improving their quality are discussed. The effect of calcination temperature on the mechanophysical and textural properties of a support and the dependence of the main parameters of catalyst quality (service life, activity, and selectivity) on the heat treatment conditions of supports were studied. It was found that the calcination of low-temperature alumina at 800°C allows us to obtain the optimum ratio of the strength and textural properties of a support for use in the synthesis of selective hydrogenation catalysts. The basic requirements for alumina used as a support are: It must have high mechanical crushing strength (more than 4 N/$ mm^{2} $). The strength of the material must be uniform; the content of granules with a strength of less than 40 N/$ mm^{2} $ in a support batch must be no greater than 5%. Losses due to attrition in aqueous and hydrocarbon environments must be no greater than 1.5 wt %. The mode of heat treatment for a support must contribute to the stability of texture characteristics during oxidative regeneration (450–500°C). © Pleiades Publishing, Ltd. 2010 |

Abstract Approaches to selecting alumina supports for the production of crust-selective hydrogenation Pd catalysts with a view to improving their quality are discussed. The effect of calcination temperature on the mechanophysical and textural properties of a support and the dependence of the main parameters of catalyst quality (service life, activity, and selectivity) on the heat treatment conditions of supports were studied.
