Mhedzisiro yebasa iri rakabudiswa mumagazini yeNanomeridhi. Munguva yekutsvawa kweHydrogen, magasi egirini haana kuumbwa, uye masero emafuta anoshanda pamusoro pesimba rayo nekunyanyisa kugona, uye saka hydrogen inoonekwa seyakavimbiswa mafuta.
Kugadzirwa kwazvino kweazvino kunobva pakushandurwa kwekubatana kwegasi kwechisikigo pamwe nemvura yemvura celsio - Ch4 naCo2. Nehurombo, iyo STOAM TOLPIONS inobata mune izvi maitiro inogadziriswa uye ichiparadzwa, uye kushandiswa kwezvinhu zvose zvinokonzeresa zveboka rePlatinamu (PT, PD, RH) hazvigone zvakare nekuda kwezvikonzero zvakasiyana.
Mukwikwidzi anokurudzira weCarbon Dioxide Shanduko CatalyStts ndeye molybdenum carbide (mo2c). Basa rayo rezvekutengesa mune zvekuita zvinosanganisira ma hydrocarbons yakafanana nePlatinamu, uye mutengo wakadzika kwazvo. Mukuwedzera, molybdenum carbide inodzivirira kune yakajairika kune yakajairika yekuona poisons - carbon sediments uye sarufa-ine makomisheni, ayo anoita zvokutonga zvichienderana nebasa rakareba. Nekudaro, molybdenum carbide haina kugoverwa mune zvakasikwa uye inogona kungowanikwa neiyo synthetic.
Muchinyakare chetsiva chesimbi, chakashongedzwa nekuda kwekutenderera kwenguva refu kwekuita kwesimbi uye kabhoni, iyo inotungamira kune yakakura simba rekushandisa. Imwe nzira yakajairwa ndiyo iyo yekutanga kuderedza kweMolybdenum oxides ine musanganiswa we hydrocarbon magasi neH2 kana Anonhuhwirira makomputa.
Iyi nzira inoda simba shoma, asi zvinoda kuwedzera matanho ekuchengetedza nekuda kwekushandiswa kwemagasi anoputika. Mukuwedzera, munzira mbiri pamusoro peiyo molybdenum carbide, firimu kabhoni inoumbwa, iyo inovhara chikamu chevanoita mashandiro emunharaunda uye nekudaro anoderedza kushanda kwekushandisa zvinyorwa. Naizvozvo, masayendisiti ari kutsvaga dzimwe nzira dzekushandiswa kwayo.
MuPCTB, Molybdenum Carbide inokurudzirwa kuti iwanikwe uchishandisa nzira yeMvura-chikamu cheMolybdenum bhuruu (SO-SO-SO-SOLASE YEMAHARA YEMAHARA YEMAHARA YEMABHUKU Mubasa, masayendisiti akaita synthesis ye mo2c mumatanho akati wandei. Pakutanga vakagamuchira molybdenum vhezheni ivo pachavo nekuda kwekudzikiswa kweApmonium Heptamolibdate solution ascorbic acid pamberi pehyrochloric acid.
Uyezve molybdenamu yebhuruu yakaomeswa uye yakadzvanywa yakagadzirirwa tembiricha ye150-800 degrees celsius, semhedzisiro iyo iyo molybdenum carbide yakaumbwa. "Musiyano mukuru webasa rinoitwa neboka redu resainzi nzira," anodaro mumwe wevanyori vebasa, purofesa wekushamwaridzana weDhipatimendi reColoid Chemistry yePCTU, Natalia Gavrilova.
Muchokwadi, isu hatina kungoita sedhesis yemasangano akapararira zvakanyanya, asi isu tinodzidza nhanho yega yega yekuwana masisitimu, kurongedza iyo yakakosha maitiro, kuti iite zvimiro zvakatsanangurwa - izvo, molybdenum carbide ne "Catalytic chiitiko."
Mubasa, vaongorori vakachinja huwandu hwechiyero cheMolybdenum-chine chekuita nechikamu chekutanga cheSynthesis uye molybdenum carbide pachayo, iyo yakanyorwa gare gare kubva mudura. Chiitiko cheCatalytic of MO2C chakaongororwa nekuitisa maitiro ekutendeuka kweMethane Commas
Izvo zvakaratidzwa kuti kare tembiricha ye850 degrees celsius, iyo degree rekushandurwa kwemakumi zana nemakumi mashanu muzana, uye Sampulized neyakaderera mumiririri wekudzora musanganiswa wekutanga: navo kushandurwa Ch4 naCo2 muSynthesis gasi rinoitika.
Nekudaro, masayendisiti akawana kuti basa guru mukuumbwa kwechimiro uye kuumbwa kwematanho anodzora mumirimo, zvinokwanisika kuwana zvasiyana-siyana zveMolybdenum carbide uye gadzirisa chimiro chekuputika yeiyo catalyst.
Iyo nzira yakagadziriswa yeSynthesis inoyerera pakudziya kwetsika (inoenzaniswa nenzira dzechinyakare), uye iyo inovhura kugona kwekutengesa nzira yekuita kuti uwedzere kutakura uye yekateni membranes yemabasa akasiyana siyana kusanganisira kushandurwa kwegasi rechisikigo.
