The diatomite: Type catalyst’s support

Abstract

Hydrogenation of the animal fats and edible oils is a very important operation in the fats and oils industry. A catalyst usually used in industrial processes of the tallow and fat hydrogenation and in the vegetable oils selective hydrogenation, is a nickel catalyst deposited on a silicate support. Choice and activation of the support are of the vital importance for obtaining a highly active hydrogenation catalyst. As a support suitable for the catalyst's synthesis, we have chosen the natural biogenic sediment rock - diatomite earth. By an appropriate chemical and thermal treatment of the domestic crude diatomite, we have obtained a type of the activated support with performances, in comparison with the same-class commercial supports, quite satisfying the requirements.

Hidrogenacija životinjskih masti i jestivih biljnih ulja je veoma važna operacija u industriji masti i ulja. Katalizator koji se uobičajeno upotrebljava u industrijskom procesu hidrogenacije masti i lojeva i u selektivnoj hidrogenaciji biljnih ulja, je nikal nanešen na silikatni nosač. Izbor i aktivacija nosača su od vitalnog značaja za dobijanje visoko-aktivnog hidrogenacionog katalizatora. Kao pogodan nosač za sintezu katalizatora odabrana je prirodna biogena sedimentna stena - dijatomejska zemlja. Pogodnim mehaničkim, hemijskim i termičkim tretmanom domaćeg sirovog dijatomita, dobijen je tip aktiviranog nosača sa zadovoljavajućim performansama u poređenju sa komercijalnim nosačima istog tipa.
