Abstract

Przedmiotem zastrzeżenia są katalizatory do syntezy amoniaku na bazie rutenu osadzonego bezpośrednio na graficie o powierzchni właściwej BET (określanej metodą Brunauera, Emetta i Tellera) powyżej 10 m<sup>2</sup>/g, korzystnie powyżej 100 m<sup>2</sup>/g i korzystniej 280 m<sup>2</sup>/g, przy czym wyżej wspomniany grafit charakteryzuje się rentgenogramem zawierającym linie dyfrakcyjne właściwe jedynie dla grafitu krystalicznego, z wyłączeniem stosownych pasm węgla amorficznego, do których to katalizatorów dodaje się jako aktywatory bar, cez i potas. Nośniki grafitowe umożliwiają uniknięcie znanych obróbek wstępnych i końcowych koniecznych w przypadku nośników otrzymanych przez częściową grafityzację węgli aktywnych, a w czasie stosowania nieznacznie wpływa na nie metanizacja wykazywana przez nośniki otrzymane z węgli aktywnych. Ponadto katalizatory według niniejszego wynalazku charakteryzują się bardzo dużą aktywnością, nawet przy zastosowaniach ilości rutenu znacznie powyżej znanego zastosowania.
