Methanol Cracking Hydrogen Production Technology siv methanol thiab dej ua cov khoom siv raw, tig cov methanol rau hauv cov pa sib xyaw los ntawm catalyst thiab purifies hydrogen los ntawm lub siab viav vias adsorption (PSA) nyob rau hauv ib qho kub thiab siab.
Cov yam ntxwv
1. Kev sib koom ua ke siab: cov cuab yeej tseem ceeb hauv qab 2000Nm3/ h tuaj yeem skidded thiab muab tag nrho.
2. Diversification ntawm cua sov txoj kev: catalytic oxidation cua sov; Self-heating flue gas ncig cua sov; Roj cua sov conduction roj rauv cua sov; Hluav taws xob cua sov cua sov conduction roj cua sov.
3. Tsawg methanol noj: qhov tsawg kawg nkaus methanol noj ntawm 1Nm3hydrogen yog guaranteed <0.5kg. Kev ua haujlwm tiag tiag yog 0.495kg.
4. Hierarchical rov qab los ntawm lub zog hluav taws xob: ua kom lub zog siv hluav taws xob zoo tshaj plaws thiab txo cov khoom cua sov los ntawm 2%;
(1) Methanol Cracking
Sib tov methanol thiab dej nyob rau hauv ib qho kev faib ua feem, pressurize, tshav kub, vaporize thiab overheat cov khoom sib tov kom ncav cuag ib tug tej yam kub thiab siab, ces nyob rau hauv lub xub ntiag ntawm catalyst, methanol cracking cov tshuaj tiv thaiv thiab CO hloov cov tshuaj tiv thaiv nyob rau tib lub sij hawm, thiab tsim ib tug gas sib tov nrog H2, CO2thiab ib qho me me ntawm cov seem CO.
Methanol cracking yog ib qho nyuaj multicomponent cov tshuaj tiv thaiv nrog ntau cov roj thiab cov tshuaj lom neeg cov tshuaj tiv thaiv
Cov tshuaj tiv thaiv loj:
| CH3OH |
| CO + H2O |
Cov ntsiab lus teb:
CH3OH + H2O CO2+ 3 H2- 49.5 kJ/mol |
Tag nrho cov txheej txheem yog txheej txheem endothermic. Lub tshav kub xav tau rau cov tshuaj tiv thaiv yog muab los ntawm kev ncig ntawm cov roj kub conduction.
Txhawm rau txuag hluav taws xob hluav taws xob, cov roj sib tov tsim tawm hauv cov reactormakes tshav kub exchanger nrog cov khoom sib tov ua kua, ces condenses, thiab yog ntxuav nyob rau hauv lub purification ntauwd. Cov kua sib tov los ntawm kev sib xyaw ua ke thiab cov txheej txheem ntxuav yog sib cais hauv cov purification ntauwd. Qhov sib xyaw ntawm cov kua dej sib xyaw no yog dej thiab methanol. Nws raug xa rov qab mus rau lub tank raw khoom rau kev rov ua dua tshiab. Cov pa tawg uas tsim nyog ces raug xa mus rau PSA chav tsev.
(2) PSA-H2
Pressure Swing Adsorption (PSA) yog raws li lub cev adsorption ntawm cov roj molecules nyob rau sab hauv ntawm ib qho adsorbent (cov khoom ntxeem tau). Lub adsorbent yog ib qho yooj yim rau adsorb high-boiling Cheebtsam thiab nyuaj rau adsorb low-boiling Cheebtsam ntawm tib lub siab. Tus nqi adsorption nce sunder siab siab thiab txo qis hauv siab. Thaum cov roj pub dhau los ntawm lub txaj adsorption nyob rau hauv ib lub siab, lub siab-boiling impurities yog xaiv adsorbed thiab qis-boiling hydrogen uas tsis yooj yim adsorbed tawm. Kev sib cais ntawm hydrogen thiab impurity Cheebtsam yog paub.
Tom qab cov txheej txheem adsorption, lub adsorbent desorbs lub absorbed impurity thaum txo lub siab kom nws yuav regenerated rau adsorb thiab cais impurities dua.
