Abstract

Det blir beskrevet en fremgangsmåte for påskyndlng av oppvarming av en faststoffkatalysator til starttempera- turen for den katalytiske reaksjonen ved tilførsel av hjelpe-energi fra eksterne energikilder l løpet av en begrenset aktlverlngstld, hvorved faststoffkatalysa- toren kan foreligge som monolitt eller l gittergodsform og har en definert tllstrømnlngsoverflate for reak- sjonsmedlene. HJelpe-energien blir tilført på en eller flere isolerte deloverflater av tilstrømningsoverflåten til katalysatoren. Derigjennom kan energibehovet for starting av katalysatoren bil holdt lavt.
