Lub tshuab hloov pauv ntawm cov tshuaj methanol (SRM) cov tshuaj tiv thaiv yields hydrogen ua nws cov khoom tseem ceeb thiab carbon dioxide thiab carbon monoxidehauv me me nrog rau tsis muaj kev cuam tshuam H 2 O and CH4. Nws yog ib qho tseem ceeb heev kom txwv tsis pub dhau lub cim ntawm CO, raws li qhov siab dua (>10 ppm) rhuav tshem cov catalyst.
Kev hloov pauv methane yog siv rau dab tsi?
Chav methane hloov kho yog cov txheej txheem siv dav tshaj plaws rau tiam ntawm hydrogen. Qhov no feem ntau yog vim nws cov txiaj ntsig zoo hauv kev tau txais qib siab ntawm purity hauv nws cov khoom tsim hydrogen. Cov hydrogen tau los ntawm SMR tuaj yeem siv rau hauv cov txheej txheem kev lag luam thiab hauv cov roj hlwb vim nws cov purity.
Kev hloov pauv chav dej yog dab tsi?
Kev hloov pauv hauv chav lossis chav methane hloov pauv yog ib txoj hauv kev tsim cov syngas (hydrogen thiab carbon monoxide) los ntawm cov tshuaj tiv thaiv ntawm hydrocarbons nrog dej . Feem ntau natural gas yog cov khoom noj. Lub hom phiaj tseem ceeb ntawm cov tshuab no yog hydrogen ntau lawm. … Cov tshuaj tiv thaiv muaj zog endothermic (siv cua sov, ΔHr=206 kJ/mol).
Methanol hloov kho ua haujlwm li cas?
Methanol chav hloov pauv hloov methanol tov rau hauv cov roj nplua nuj hydrogen uas muaj cov pa roj carbon monoxide, carbon dioxide thiab cov dej tsis siv thiab cov pa methanol hauv cov tshuaj tiv thaiv catalytic ntawm qhov kub thiab txias. qis li 200 ° C-350 ° C thiab siv cov khoom siv hluav taws xob pheej yig tooj liab [5].
Methanol synthesis yog dab tsi?
Methanol yog tsim los ntawm synthesis gas (carbon monoxide thiab hydrogen), nws tus kheej muab tau los ntawm roj, thee lossis, nce, biomass. Nws tuaj yeem dhau los ua lub hauv paus rau kev txhim kho biorefineries ua qhov nruab nrab hauv kev hloov pauv ntawm biomass rau cov khoom siv tau zoo.
