Txheej txheem thiab Catalyst rau Alkyne Hloov ntawm Benzene thiab Hnyav Aromatic Hydrocarbons
Txheej txheem cej luam
Benzene thiab C-9 aromatics alkyl hloov pauv catalyst thiab nws cov txheej txheem thev naus laus zis (BAT siv benzene thiab C-9 thiab siab dua cov tshuaj tsw qab ua cov khoom siv raw los tsim cov toluene thiab C-8 aromatics los ntawm alky hloov tshuaj tiv thaiv yog ib qho tseem ceeb txhais tau tias kom optimize thiab kho cov qauv ntawm cov khoom aromatics, nyob rau hauv cov ntaub ntawv ntawm oversupply ntawm benzene los yog benzene nqi khw Hloov tshuab siv los hloov benzene rau xylene nrog tus nqi ntxiv thiab toluene nrog kev lag luam siab Ntxiv rau, BAT thev naus laus zis tuaj yeem txuas ntxiv nrog toluene duab xaiv qhov tsis sib xws (S.STDP) lossis toluene methanol methylation technology (s-MTX) tsim los ntawm BAT unit yog siv los ua cov khoom siv hauv cov khoom siv los tsim cov khoom siv hluav taws xob (S.STP). benzene generated los ntawm SSTDP chav tsev yog siv los ua raw khoom los muab lub BAT chav tsev, BATSTDP los yog BAT-MTX txheej txheem kev sib xyaw ua ke tuaj yeem ua rau cov khoom siv tshuaj tsw qab C-8 uas yog cov khoom siv zoo rau kev tsim PX.
BAT Catalyst
Lub hom phiaj tseem ceeb ntawm benzene thiab carbon- cuaj alkyl hloov pauv yog BAT100, thiab cov yam ntxwv tseem ceeb yog raws li hauv qab no:
◆ Ntau yam ntawm cov khoom siv raw: cov khoom siv raw benzene / C, * A yog 0/10050/50wt%, pub piv tuaj yeem hloov kho raws li cov khoom xav tau.
◆ Kev ua haujlwm siab: Raws li WHSV Tsawg dua lossis sib npaug li 4h', H / HC Ntau dua lossis sib npaug rau 2 (mol / mol) cov xwm txheej, tag nrho cov kev hloov pauv ntawm 50wt%.
◆ High selectivity: Nyob rau hauv benzene / A =50/50 (wt) raw khoom muaj pes tsawg leeg, tag nrho selectivity ntawm toluene thiab C-8 aromatic hydrocarbons generated Ntau tshaj los yog sib npaug rau 90wt%.
◆ Tsawg ethylbenzene cov ntsiab lus: muaj kev ua haujlwm zoo heev, cov khoom EB / C8A<2%, suitable for producing high-quality xylene.
BAT-STDP Combined Technology
Lub alkyl hloov tshuab ntawm benzene thiab C9 aromatic hydrocarbons tuaj yeem ua ke nrog toluene duab disproportionation thev naus laus zis los yog toluene methylation thev naus laus zis los ua kom muaj txiaj ntsig thiab lub zog-txuag kev sib xyaw ua ke, uas tuaj yeem ua kom zoo dua cov khoom lag luam ntawm cov khoom muaj ntxhiab tsw thiab paub lub hom phiaj ntawm cov txheej txheem luv luv nthuav dav, tshwj xeeb tshaj yog rau kev txhim kho cov khoom siv aromatic uas twb muaj lawm.
Kev txhawb nqa thiab kev thov
BAT unit technology thiab BAT-STDP ua ke txheej txheem thev naus laus zis tau siv hauv kev lag luam ntawm Sinopec Tianjin Company. thiab cov paraxylene concentration nyob rau hauv cov khoom tom qab cov txheej txheem ua ke yog ntau dua los yog sib npaug rau 50%, uas yog conducive rau tus nqi qis - expansion PX adsorption cais unit.
