Kugwiritsa ntchito boehmite yachinyengo

Pakadali pano, kugwiritsa ntchito kwakukulu kwa pseudo-boehmite ndi chinthu chopangira alumina ndi guluu wopangira chothandizira chovuta kupanga kapena chonyamulira chothandizira. Alumina yokonzedwa powotcha pseudo-boehmite ili ndi malo apadera kwambiri ndipo imagwiritsidwa ntchito kwambiri ngati chothandizira komanso chonyamulira chothandizira mumakampani opanga mafuta.

1. yogwiritsidwa ntchito popanga zipangizo zopangira alumina ndi nanometer

Chimodzi mwa zinthu zofunika kwambiri zomwe zimagwiritsidwa ntchito popanga pseudo-boehmite ndi zinthu zopangira aluminiyamu. Kutengera mawonekedwe a malo akuluakulu, ntchito yayikulu komanso kuthekera kwamphamvu kwa zinthu zopangira, yagwiritsidwa ntchito popanga zinthu zopangira kutentha kwambiri monga zinthu zopangira aluminiyamu nitride. Kuphatikiza apo, nano-Al2O3 ndi yoyenera kwambiri popanga mankhwala opangira makina (CMP), pogwiritsa ntchito nano-Al2O3 chifukwa tinthu tating'onoting'ono tomwe timapangidwa ndi CMP slurry tingagwiritsidwe ntchito pakati pa njira yopangira IC monga zinthu zopangira ma waya a semiconductor ndi zinthu zopangira mafilimu monga tungsten, aluminiyamu, copper flattening, ndi galasi lapamwamba la optical, quartz crystal ndi mitundu yosiyanasiyana ya miyala yamtengo wapatali.

Chithunzi -Al2O3 chingagwiritsidwe ntchito popaka mankhwala pogwiritsa ntchito makina opukutira

2.Pakuti chothandizira cha hydrogenation

Pofuna kukwaniritsa zofunikira pakugwiritsa ntchito mafuta ndi mafuta oyera, ukadaulo wa hydrogenated wakhala ukugwiritsidwa ntchito kwambiri, chothandizira cha hydrogenation ndiye maziko a ukadaulo wa hydrogenation, chomwe chimagwiritsidwa ntchito pothandizira hydrogenation, chonyamulira cha gamma alumina nthawi zambiri chimakhala ndi diaspore yopyapyala pang'ono powotcha madzi m'thupi, chimakhala ndi malo akeake, malo olowera ndi osinthika, ndipo pamwamba pake pali malo osiyanasiyana a acidic. Mphamvu yabwino yamakina komanso kukhazikika kwa kutentha, komanso mawonekedwe otsika mtengo.

Zojambulajambula ndizofunikira kwambiri popanga zinthu zamafuta

Mu mafakitale amakono oyenga mafuta ndi mankhwala, njira yopitilira 90% ya mankhwala imachitika pogwiritsa ntchito njira yopangira zinthu, kotero chothandizira chakhala chinsinsi chopezera njira yatsopano yoyenga ndi mankhwala, chitukuko cha zinthu zatsopano. Mumakampani oyenga mafuta, ma catalyst olimba amagwiritsidwa ntchito kwambiri, omwe amapangidwa ndi chonyamulira ndi gawo logwira ntchito. Chonyamuliracho ndi gawo lapadera la chothandizira cholimba, chomwe chingawonjezere malo enieni, kuonjezera kukana kutentha ndi mphamvu zamakanika. Chothandizirachi chimagwiritsa ntchito mitundu yambiri ya chonyamulira, monga: alumina, sieve ya molecular, silica gel, silica gel, activated carbon ndi diatomaceous earth. Komabe, kuchuluka kwa chonyamulira cha alumina kumaphatikizapo zoposa theka la kuchuluka kwa chonyamulira cha chothandizira. Chothandizira cha Catalytic cracking (FCC) ndiye maziko a njira yopangira zinthu. Monga mafuta osaphika padziko lonse lapansi olemera komanso otsika, mu zinthu zopangira zinthu zopangira zinthu zosakaniza mafuta olemera, mafuta otsala akhala njira yogwiritsidwa ntchito kwambiri yopangira zinthu, kotero chothandizira cha mafuta chothandizira (FCC) chiyenera kukhala mafuta olemera ofalitsa mamolekyulu a dzenje lalikulu, ndipo dzenje lalikulu pakati liyenera kukhala ndi kuchuluka koyenera kwa asidi, mu kuti akonze luso lotha kusweka kwa ma macromolecular compounds mu zinthu zopangira. Alumina yogwira ntchito imagwiritsidwa ntchito kwambiri pokonza matrix ya catalyst. Kuchuluka kwa ma pore ambiri kumathandiza kuti ma macromolecular compounds afalikire mu tinthu ta catalyst, pomwe malo apamwamba kwambiri amathandiza kuti chitsulo chogwira ntchito chifalikire, kuti chiwongolere momwe catalyst imagwirira ntchito.

3. Imagwiritsidwa ntchito ngati guluu

Chonyamulira cha diaspore choonda chomwe chimagwiritsidwa ntchito ngati cholumikizira sichimangopindulitsa pakuumba, komanso chimakhudza magwiridwe antchito a chothandizira, ofufuza mu chothandizira cha flue gas denitration selective catalytic reduction Ce – Mn/TiO2 polumikizana ndi chothandizira choonda ngati cholumikizira, adapeza kuti sikuti chimangowonjezera mphamvu ya makina a chothandizira, komanso chimawongolera chothandizira cha denitration surfactant.

4. kukonza chophimba cha -Al2O3

Ntchito yopaka utoto wosanjikiza pamwamba pa chonyamulira chophimba pamwamba ndikuwonjezera malo enieni a pamwamba pa njira yomwe imagwiritsidwa ntchito kwambiri, gamma alumina ndi imodzi mwa zinthu zomwe zimagwiritsidwa ntchito kwambiri, zomwe zimakhala ndi malo akeake apamwamba, zimathandiza kuti gawo logwira ntchito ligawidwe bwino panthawi yopatsirana, kukonzekera utoto wa gamma alumina womwe umagwiritsidwa ntchito kwambiri pa AlOOH precursor sol, alumina sol kukhala yopyapyala ngati zinthu zopangira, kukonzekera, pogwiritsa ntchito njira ya acid peptization yosavuta kulamulira, ingagwiritsidwe ntchito popanga mafakitale.
