I-Dehydrogenation catalyst

I-High Temperature Dehydrogenation Catalytic Technology

Okufana ne-iron oxide - i-chromium oxide - i-potassium oxide ingenza i-ethylbenzene (noma i-n-butene) i-dehydrogenation ibe yi-styrene (noma i-butadiene) ngaphansi kwezinga lokushisa eliphezulu kanye nenani elikhulu lomhwamuko wamanzi.

izinga lokushisa eliphansi le-dehydrogenation catalytic technology

Ngenxa yokuthi i-dehydrogenation ngokuvamile idinga ukwenziwa ezingeni lokushisa eliphezulu, i-decompression noma phambi kwenani elikhulu lama-diluent, ukusetshenziswa kwamandla kukhulu.Eminyakeni yamuva nje, i-oxidative dehydrogenation emazingeni okushisa aphansi iye yathuthukiswa.Njenge-polyethylene ene-bismuth - i-molybdenum metal oxide catalyst nge-oxidative dehydrogenation ye-butadiene.

I-Hydrogenation catalyst

I-Hydrogenation catalystayisetshenziswa kuphela enqubweni yokukhiqiza, kodwa futhi isetshenziswa kabanzi ekucwengisweni kwezinto ezingavuthiwe nemikhiqizo.Ngokwezimo ezahlukene ze-hydrogenation, ingahlukaniswa ngezigaba ezintathu:

① Izisusa ezikhethiwe ze-hydrogenation, ezifana ne-ethylene ne-propylene ezitholakala ku-petroleum hydrocarbon cracking njengezinto zokusetshenziswa ze-polymerization, kumele ziqale zikhethwe nge-hydrogenation, ukususa ukungcola okulandela umkhondo okufana ne-alkyne, i-diene, i-carbon monoxide, i-carbon dioxide, i-oxygen, futhi akukho ukulahlekelwa kwe-ene .I-catalyst esetshenziswayo ngokuvamile i-palladium, iplatinum noma i-nickel, i-cobalt, i-molybdenum, njll., ku-alumina.

② I-Non-elective hydrogenation catalyst, okungukuthi, i-catalyst esetshenziselwa i-hydrogenation ejulile kuya kumakhemikhali agcwele.Okufana ne-benzene hydrogenation kuya ku-cyclohexane ene-nickel-alumina catalyst, i-phenol hydrogenation kuya ku-cyclohexanol, ine-dinitrile hydrogenation ku-hexdiamine nge-nickel catalyst.

③ I-Hydrogenation catalyst, njenge-copper chromate catalyst ye-hydrogenation kawoyela ukukhiqiza utshwala obuphezulu

I-Hydroformylation catalyst

Kuyi-catalyst yokuqala eyinkimbinkimbi esetshenziswa ekukhiqizeni izimboni.Ama-aldehyde ane-athomu eyodwa yekhabhoni akhiqizwa ukusabela kwe-alkenes nge-syngas (CO+H2) phambi kwe-catalyst.Njenge-ethylene, i-propylene njengezinto zokusetshenziswa nge-hydroformylation (okungukuthi, eyaziwa ngokuthi i-carbonyl synthesis) i-propyl aldehyde, i-butyl aldehyde.I-Hydroformylation yenziwa esigabeni se-liquid ekushiseni okuphezulu nokucindezela kusetshenziswa i-carbonyl cobalt complex njenge-catalyst.

I-polymerization catalyst

I-polyethylene ihlukaniswe ngokuyinhloko ibe yi-low density kanye ne-high density.Esikhathini esedlule, abangaphambili babesebenzisa indlela yokucindezela okuphezulu (100 ~ 300MPa) ukukhiqizwa, umoya-mpilo, i-organic peroxide njenge-catalyst.Lokhu kokugcina kukhiqizwa ngokuyinhloko indlela yokucindezela okuphakathi noma indlela yokucindezela okuphansi.Ngendlela yengcindezi emaphakathi, i-chromium-molybdenum oxide iphathwa ku-silicon aluminium glue njengesisusa.Ngendlela yengcindezi ephansi, i-Ziegler type catalyst (emelwe i-titanium tetrachloride kanye ne-triethyl aluminium system) isetshenziselwa i-polymerization ekushiseni okuphansi nokucindezela okuphansi.Ukukhiqizwa kwe-polypropylene kuphinde kwathuthukisa uhlelo olusekelwe lwe-titanium-aluminium lwe-catalyst esebenza kahle kakhulu, igremu ngalinye le-titanium lingakhiqiza ngaphezu kwe-1000kg ye-polypropylene.

I-Alumina catalyst

Okwedlule: I-Oxidation Catalyst ne-Liquid phase oxidation catalyst
