Oxidation Catalyst & Liquid phase oxyde cataliste
Iyo Ethylene na propylene biboneka muri peteroli ya hydrocarubone ikoreshwa nkibikoresho bya polymerisation, hydrogenation yatoranijwe irasabwa gukuraho umwanda wanduye nka alkyne, diene, monoxide carbone, dioxyde de carbone na ogisijeni, nta gutakaza olefine.Cataliseri ikoreshwa ni palladium, platine cyangwa nikel, cobalt, molybdenum, nibindi, kuri alumina.Guhitamo hydrogenations hamwe nibintu bitandukanye birashobora kuboneka mugucunga ingano yibintu bifatika, uburyo bwo gukora bwo gutera inkunga na catalizator.Ibindi nko gutobora lisansi, kugabanya hydrogenation ya nitrobenzene kuri aniline, catisale ya hydrogenation.
Cataliseri ya hydrogenation yimbitse kubintu byuzuye.Nka hydrogenation ya benzene kuri cyclohexane hamwe na catalizike ya nikel alumina, hydrogenation ya cyclohexanol, ifite hydrogenation ya dinitrile kuri hexdiamine hamwe na catalizike ya nikel.
Gukoresha karibide ya silicon cyangwa α -alumina nkinkunga (hamwe na oxyde ya barium nka cocatalyst).Nyuma yo gukomeza kunoza catalizator nuburyo ibintu bigenda, umusaruro wibiro bya Ethylene warenze 100%.
Cataliseri yatewe kuri karubide ya silicon cyangwa corundum kugirango okiside ya o-xylene kuri anhydride ya phthalic.Cataliste yateguwe mugutera ibice bigize oxyde ya vanadium-molybdenum kuri corundum kugirango okiside ya benzene cyangwa butane kuri anhydride yumugabo.Iterambere ryubu bwoko bwa catalizator ni iterambere ryibice byinshi, ibice umunani bigize catalizator byagaragaye.Imiterere yabatwara nayo yahinduwe kuva kumurongo ukazenguruka, kuzenguruka kugirango byoroherezwe ubushyuhe.Icyerekezo rusange ni ugukurikirana umutwaro mwinshi, umusaruro mwinshi hamwe nubuziranenge bwibicuruzwa.
Nka okiside ya methanol muri formaldehyde hamwe na silver - pumice (cyangwa alumina), oxyde de fer - okiside ya molybdenum na catalizike ya electrolytike.
Mu myaka ya za 1960, hashyizweho umusemburo urimo bismuth-mo-fosifore compound oxyde catisale.Acrylonitrile irashobora guhuzwa murwego rumwe wongeyeho propylene, ammonia numwuka kuri catalizator.Mu rwego rwo kunoza guhitamo no gutanga umusaruro no kugabanya ihumana ry’ibidukikije, ibihugu bitandukanye bihora bitezimbere umusemburo, kandi bimwe mu bintu bishya birimo ibintu bigera kuri 15.Oxygene ya chlorine catisale, 60′s yateje umuringa wa chloride alumina catalizator, mumashanyarazi yigitanda cyamazi binyuze muri Ethylene, hydrogène chloride numwuka cyangwa ogisijeni irashobora kubona dichloroethane.Dichloroethane yari pyrolyzed kugirango ikore vinyl chloride monomer.Ubu buryo ni ingirakamaro mu iterambere rya PVC mu bice aho amashanyarazi ahenze ndetse na peteroli yateye imbere, uburyo bwo gukora inkunga na catalizator.Ibindi nko gutobora lisansi, kugabanya hydrogenation ya nitrobenzene kuri aniline, catisale ya hydrogenation.
Amazi ya fiside ya okiside
Hariho ahanini:
.chloride y'umuringa wa chloride yumuti, binyuze muri olefin, umwuka cyangwa ogisijeni, nyuma yintambwe imwe cyangwa ebyiri zo kwitwara kugirango ubone ibisabwaumwuka wa ogisijeni.Ingaruka ni ruswa ikomeye yibikoresho bya reaction.
(2) Okiside ya Aromatic kuruhandekuri catalizike ya aryl, nka p-xylene mumuti wa acide acetike hamwe na cobalt acetate hamwe na bromide ya amonium nkeyagushyushya, umwuka wa okiside yumuyaga terephthalic, ariko kwangirika gukomeye kwibikoresho.
Andika ubutumwa bwawe hano hanyuma utwohereze
