Abstract

Postupak za pripremanje katalizatora sacinjenog od porozne podloge koja na sebi ima metalni paladijum i zlato, a koji obuhvata impregnisanje te podloge vodorastvorljivim jedinjenjima ovih plemenitih metala, pretvaranje apsorbovanih vodorastvorljivih jedinjenja plementih metala u vodonerastvorljiva jedinjenja plemenitih metala, dovodjenjem impregnisane podloge u jednom stupnju fiksiranja u dodir sa rastvorom koji sadrzi jedno jedinjenje koje reaguje sa pomenutim vodorastvorljivim jedinjenjima plemenitih metala, radi nanosenja na tu podlogu vodonerastvorljivih jedinjenja plemenitih metala i redukovanje tih vodonerastvorljivih jedinjenja plemenitih metala nekim gasom za redukovanje radi obrazovanja slobodnih metala na toj podlozi, naznacen time, sto se sastoji u (1) dovodjenju pomenutih podloga u dodir sa jednim od pomenutih vodorastvorljivih jedinjenja pomenutih plemenitih metala radi natapanja podloge vodorastvorljivim jedinjenjem, (2) pretvaranju ovog vodorastvorljivog jedinjenja plemenitog metala u vodonerastvorljivo jedinjenje plemenitog metala dovodjenjem impregnisane podloge u prvom stupnju fiksiranja u dodir sa rastvorom koji sadrzi jedinjenje koje reaguje sa tim vodorastvorljivim jedinjenjem da bi se na podlogu nanelo vodonerastvorljivo jedinjenje tog plemenitog metala, (3) dovodjenju po prvi put impregnisane i fiksirane podloge u dodir sa drugim od vodorastvorljivih jedinjenja pomenutog plemenitog metala radi natapanja podloge vodorastvorljivim jedinjenjem, (4) pretvaranju tog drugog vodorastvorljivog jedinjenja pomenutog plemenitog metala u vodonerastvorljivo jedinjenje plemenitog metala dovodjenjem impregnisane podloge u drugom stupnju fiksiranja u dodir sa drugim rastvorom koji sadrzi jedno jedinjenje koje reaguje sa ovim drugim vodorastvorljivim jedinjenjem da bi se na podlogu natalozilo drugo vodonerastvorljivo jedinjenje plemenitog metala, i zatim u redukovanju ovih vodonerastvorljivih jedinjenja plemenitog metala radi obrazovanja slobodnih plemenitih metala na pomenutoj podlozi. Prijava sadrzi jos 10 zavisnih patentnih zahteva.
