Ibisubizo by'akazi byasohotse mu kinyamakuru Nanomarial. Mugihe cyo gutwika hydrogen, imyuka ya parike ntabwo ikozwe, kandi selile ya lisansi ikorera mumashanyarazi akora neza cyane, bityo hydrogen ifatwa nkizangiza lisansi.
Umusaruro wacyo ugezweho ushingiye ku guhindura gaze gasanzwe hamwe n'umwuka w'amazi wakozwe na dogere 1000, ariko uburyo bw'ibidukikije bwa dioxyde ya dishane, gaze ya karubone iyo gaze ya grihouse ikoreramo icyarimwe - Ch4 na CO2. Kubwamahirwe, ihinduka rya steam ryamavumwe muriyi nzira rirahagarikwa kandi rirasenywa, kandi ikoreshwa rya katalizeli yose rishingiye ku miterere ya platine (PT, PD, na RH) ntibishoboka kubwimpamvu zitandukanye.
Umukandida usezeranya ikizere kuri kaburimbo ya karubon dioxydes ni molybdenum carbide (mo2C). Igikorwa cyacyo cya catalytic mubyitwazo kirimo hydrocarbone zigereranywa na platine, kandi igiciro kiri hasi cyane. Byongeye kandi, molybdenum ya molybdenum irwanya uburozi rusange - imyanda ya karubone hamwe na sulfure-irimo ibice birimo, bituma habaho incamake, bituma habaho incamake ishingiye ku bikorwa irambye hamwe nakazi karambye. Ariko, karbide ya Molybdenum ntabwo ikwirakwizwa muri kamere kandi irashobora kuboneka gusa na Sintetike.
Muburyo bwuzuye bwa Metallurgical, ni synthesied kubera gutunganya ubushyuhe bwiburebure bwa cyuma na karubone, biganisha ku gukoresha ingufu. Ubundi buryo busanzwe ni ukugabanya imva ya molybdenum hamwe nuruvange rwa myuka ya hydrocarbone hamwe nibigize H2 cyangwa impumuro.
Ubu buryo bukeneye imbaraga nke, ariko bisaba ingamba zumutekano bitewe no gukoresha imyuka iturika. Mubyongeyeho, muburyo bwombi hejuru ya karbide ya Molybdenum, hashyizweho film ya karubone, hashyizweho film ya karubone, ihagarika igice cyibigo bikora bike kandi bigabanya imikorere yo gukoresha ibikoresho. Kubwibyo, abahanga bashaka ubundi buryo bwa synthesis.
Muri PCTU, Molybdenum Carbide asabwa kuboneka hakoreshejwe uburyo bw'ikigereranyo cy'icyiciro cya Molybdenum ubururu bwa Molybdenum (yiswe gutanyagura amatsinda ya Molybdenum na ogisijeni). Mu kazi, abahanga bakoraga synthesis ya Mo2C mu byiciro byinshi. Ubwa mbere bakiriye ubururu bwa molybdenum kubera kugabanya ammonium heptamobdate igisubizo aside aside acide imbere ya aside hydrochloric.
Hanyuma molybdenum ubururu bwumutse kandi bwabonwa nyabokara ku bushyuhe bwa dogere 750-800, kubera akaba ya Molybdenum. Umwarimu w'ishami b'umurimo wa Colloid w'ishami mu ishami ry'abapadiri b'ishami rishinzwe ishami rishinzwe ishami rishinzwe ishami rishinzwe ishami rishinzwe ishami rishinzwe ishami rishinzwe ishami rishinzwe ishami rishinzwe ishami rishinzwe ishami rishinzwe ishami rya Colleid rivuga ko Porofeseri w'ishami w'ishami rishinzwe PCCU, Natalia Gavrilova yacu. "
Mubyukuri, ntabwo twishora muri synthesis gusa kubice byatatanye cyane, ariko twiga buri cyiciro cyo kubona sisitemu ya kataletic, bituma habaho uburyo nyamukuru bwibicuruzwa hamwe nibicuruzwa byagenwe - nibyo, MolyBdenum Carbide hamwe ibikorwa byo hejuru bya katailtic. "
Mu kazi, abashakashatsi bahinduye igipimo cy'ibintu bya Molybdenum ndetse n'umukozi wo kugabanya mu cyiciro cya mbere cya Synthese kandi bikaba byimuka molybdenum ya molybdenum yavuyemo, muri Molybdenum ubwayo, nyuma yaho nyuma yo kurangi. Igikorwa cya kataletike cya mo2C cyasuzumwe ukora reaction yo guhindura methane ch4 (igice kinini cya gaze ya gaze) na CO2 mu ruvange rwa H2, CO na H2O, ni ukuvuga gaze ya Synthesi.
Byaremwe ko bimaze ku bushyuhe bwa dogere 850, urwego rwa methane ni 100 ku ijana, na disces hamwe nibikorwa byo kugabanya, hakomatanya ibintu byo kugabanya mu ruvange rwambere: hamwe nabo guhinduka CH4 na CO2 muri gazi ya synthesi ibaho.
Rero, abahanga basanze uruhare nyamukuru mugushinga imiterere nuburyo bwimiterere yumusemburo bugabanya inzira zinyuranye, birashoboka kubona sisitemu itandukanye ya molybdenum kandi igahindure imiterere y'umusemburo.
Uburyo bwateye imbere bwa synthesis butemba ku bushyuhe buke ugereranije), hamwe na mo2C gakondo, kandi ifungura ubushobozi bwo gukoresha ubu buryo bwo gukoresha ubukungu bwa mutwara hamwe na Cataltic mu mirimo itandukanye - harimo guhindura gaze karemano.
