Untersuchung von mechanisch aktivierten Kontakten. Die mechanische Aktivierung von Nickel‐Pulver zum Kontakt

Abstract: Technisches und reduziertes Nickel‐Pulver werden in einer Schwingmühle behandelt und zeigen danach starke katalytische Aktivität. Als Testreaktion diente die Benzol‐Hydrierung. Der Festkörperzustand dieser mechanisch aktivierten Kontakte wird durch Oberflächenbestimmung sowie durch röntgenographische, magnetische und kinetische Messungen untersucht. Durch Vergleich der katalytischen Aktivität mit der Oberflächengröße bzw. dem Gitterzustand ergibt sich aus den kinetischen Meßdaten, daß die katalytische Aktivitä… Show more

“…115 ± 118 Deactivation of catalysts upon heating was associated with dislocation and annihilation of vacancies. 118 A nickel powder treated in a ball mill increased its activity in the hydrogenation of benzene, 113,119 phenol and higher alcohols 120 and fats. 121 Correlation of the nickel activity in the above-mentioned reactions with changes in its physicochemical properties suggests that the increase in activity is to a larger extent associated with disordering of the crystal lattice than to the surface area increase.…”
