Technology thiab Catalyst rau xob laim hnyav Aromatics

Hnyav thiab lub teeb uas muaj ntxhiab hydrocarbons yog tsim los ntawm dealkylation thiab alkyl hloov cov tshuaj tiv thaiv siv cov pa roj carbon -9 thiab siab dua cov ntxhiab hydrocarbons ua raw khoom. Cov txheej txheem S-HAPheavy aromatics lub teeb yuag tsim los ntawm ShanghaiInstitute siv C thiab hnyav aromatics raws li raw cov ntaub ntawv los tsim BTX thiab by-produce C2-C3 alkanes los ntawm lub teeb yuag, nyob rau hauv uas benzene thiab toluene yuav muab rho tawm raws li kev thov, los yog rov siv dua los ua kom muaj txiaj ntsig zoo tshaj plaws ntawm C-8 aromatics. Cov thev naus laus zis tuaj yeem hloov pauv C, cov khoom muaj ntxhiab hnyav hauv catalytic hloov pauv roj rau hauv cov khoom sib xyaw xylene thiab olefin cracking raw cov ntaub ntawv, uas ua tau raws li cov kev xav tau ntawm kev hloov kho cov roj zoo thiab cov khoom tsim kho thiab pab cov tuam txhab petrochemical kom paub txog kev hloov pauv roj-tshuaj lom neeg.

S-HAP hnyav aromatics lub teeb yuag thev naus laus zis tsim los ntawm Shanghai Lub Tsev Kawm Ntawv muaj txoj cai ywj pheej ntawm kev txawj ntse thiab tau txais ntau tshaj 10 daim ntawv tso cai tsim khoom hauv Suav teb.

S-HAP hnyav aromatic lightening tshuab yog siv los tsim xylene los ntawm C thiab hnyav aromatic hydrocarbons qhia cov roj los ntawm cov txheej txheem ntawm dealkylation thiab alkyl hloov. Lub tshuab siv HAP hnyav aromatic lub teeb catalyst, thiab nws cov yam ntxwv ntawm kev ua tau raws li hauv qab no:

◆ Kev ua haujlwm yooj yim: Cov khoom siv raw muaj pes tsawg leeg thiab cov khoom lag luam tuaj yeem hloov kho, benzene thiab toluene tuaj yeem siv los ua cov khoom tsim tawm, tab sis kuj yog cov khoom siv raw.

◆ Cov khoom muaj ntau haiv neeg: Cov khoom zoo xylene thiab zoo olefin cracker yog tsim los ntawm kev siv C thiab hnyav aromatics hauv cov roj hloov kho raws li cov khoom siv raw, thiab cov qauv ntawm cov roj refinery, aromatics thiab olefin yog optimized.

◆ High reaction efficiency: One-way conversion rate of heavy aromatics >55wt%, selectivity of xylene >80wt%, FB / C.AS5% hauv cov khoom.

Qhov hnyav aromatics lub teeb catalyst yog HAP series catalyst, cov yam ntxwv tseem ceeb ntawm cov khoom yog raws li hauv qab no:

◆ Kev ua haujlwm siab: WHSV<4h-', H/HC>2 (mol/mol) conditions, C, A one-way conversion rate >55 wt% ib.

◆ High selectivity: the light products of heavy aromatics are BTX and C2C3 alkanes, while the main products of benzene and toluene are xylene after self-cycling; The selectivity of xylene was determined by the composition of raw material, and the selectivity of xylene in reforming heavy aromatic material was >80 wt%.

◆ High stability: the catalyst life is >4 xyoo thaum ua haujlwm nrog kev hloov kho cov khoom siv raw khoom hnyav, thiab cov tshuaj tiv thaiv kev ua haujlwm tau ruaj khov thaum lub sijhawm ua haujlwm.

◆ Tsawg hydrogen noj: Raws li kev hloov kho cov khoom siv roj tsw qab hnyav, kev siv hydrogen<4kg hydrogen ton feed.

Xyoo 2016, HAP catalyst tau siv rau hauv 1 lab tons / xyoo kev lag luam cog rau txawv teb chaws, cov nroj tsuag khiav ruaj khov, thiab cov kev ua haujlwm catalyst thiab xaiv tau zoo.

Xyoo 2021, thawj lub tsev cog khoom siv hluav taws xob hnyav hnyav siv S-HAP thev naus laus zis yuav ua tiav thiab muab tso rau hauv kev ua haujlwm.
