Inkxaso yeCatalyst

I-Catalyst carrier yinxalenye ekhethekileyo ye-solid catalyst, i-dispersant, i-binder, i-negative carrier ye-active component ye-catalyst, kwaye ngamanye amaxesha i-ACTS njenge-co-catalyst okanye i-co-catalyst. I-Catalyst carrier, eyaziwa ngokuba yi-support, yenye yezinto ze-supported catalyst. Ngokubanzi, yinto enemingxuma enendawo ethile yomphezulu, kwaye i-active component ye-catalyst idla ngokunamathela kuyo. I-catalyst isetyenziselwa kakhulu ukuxhasa i-active component, ukuze i-catalyst ibe neempawu ezithile zomzimba, ngelixa i-catalyst ngokwayo ingenawo umsebenzi we-catalytic.

Iimfuno zenkxaso yeCatalyst

1, inganciphisa uxinano lwezinto ezisebenzayo, ingakumbi iintsimbi ezixabisekileyo

2, ingalungiswa ibe yimo ethile

3. Ukuqhekeka phakathi kwezinto ezisebenzayo kunokuthintelwa ukuya kuthi ga kwinqanaba elithile

4, inokumelana netyhefu

5. Inokuba nefuthe elifanayo necandelo elisebenzayo kunye ne-catalyst ephambili.

Isiphumo somthwali we-catalyst

1, nciphisa iindleko ze-catalyst

2, ukuphucula amandla oomatshini e-catalyst

3. Phucula uzinzo lobushushu be-catalyst

4, yongeza umsebenzi we-catalyst kunye nokukhetha

5. Yandisa ubomi be-catalyst

Kuqaliswa iindlela ezininzi zokuthwala izinto eziphambili

1. I-alumina esebenzayo: eyona nto isetyenziswa kakhulu kwiikhatalyst zemizi-mveliso. Ixabiso eliphantsi, ukumelana nobushushu obuphezulu, ukuhambelana kakuhle kwezinto ezisebenzayo.

2. Ijeli yeSilica: ukwakheka kweekhemikhali yiSiO2. Ngokwesiqhelo yenziwe nge-sodium silicate (na 2 si 3) acid. I-silicate acid yakhiwa emva kwesiphumo se-sodium silicate kunye ne-asidi. I-silicic acid polymerization, i-condensation, kunye nolwakhiwo lwe-polymer aluqinisekanga.

I-SiO2 sisithwali esisetyenziswa kakhulu, kodwa ukusetyenziswa kwayo kwimizi-mveliso kungaphantsi kwe-Al2O3, okubangelwa bubunzima bokulungiselela, ubuthathaka bokunamathelana kwezinto ezisebenzayo, ukucocwa lula ngumphunga wamanzi kunye nezinye iziphene.

3. I-Diatomite: i-SiO2 yendalo. Iqulethe ii-oxides zesinyithi ezimbalwa kunye nezinto eziphilayo, kunye nolwakhiwo lwe-pore kunye notshintsho oluthile lomphezulu oluvela kuyo. Unyango lwe-asidi kufuneka lusetyenziswe ngaphambi kokusetyenziswa. Enye kukuphucula umxholo we-SiO2 kunye nokunyusa umphezulu othile, umthamo othile we-pore kunye ne-radius ye-pore ephambili. Eyesibini kukuphucula uzinzo lobushushu, emva konyango lwe-asidi, kunokunyusa ngakumbi umphezulu othile. I-Diatomite isetyenziselwa ngokuyintloko ukulungiselela ii-catalysts ezisisigxina.

4, i-activated carbon: isithako esiphambili yi-C, equlethe i-H, O, N, S kunye nothuthu, njl. njl. I-activated carbon inesakhiwo esingaguqukiyo se-stone mill, kukho iqela le-carbonyl, iqela le-quinone, iqela le-hydroxyl kunye neqela le-carboxyl kumphezulu. I-activated carbon ibonakaliswa zii-pores eziphuhlileyo kunye nommandla omkhulu womphezulu, uzinzo lobushushu kunye nokuphakama.

5. I-TiO2: ineemilo ezintathu zekristale: i-anatase, ipleyiti yetitanium kunye ne-rutile. I-sheet titanium ore kunzima ukuyivelisa ngenxa yokungazinzi; I-Anatase yenziwa kubushushu obuphantsi obunoxinano oluhambelanayo lwe-3.84 kunye nommandla omkhulu womphezulu othile. Ishushu kwi-600 ~ 1000°C, i-anatase iba yi-rutile, enoxinano oluhambelanayo lwe-4.22 kunye nommandla omncinci womphezulu othile.

6. I-silicon carbide: iqondo lokunyibilika kwe-carbide ceramics liphezulu kune-2000°C, linobushushu obuphezulu, ubulukhuni obuphezulu, ukumelana nobushushu obunamandla kunye nokumelana nempembelelo, kodwa i-oxidized kwi-oxygen atmosphere. Ngoko ke i-SiC idla ngokusetyenziswa njengomthwali we-catalyst kwindawo enobushushu obuphezulu.

7. Isihluzo seMolekyuli: sisilicate esikristale okanye i-silicoaluminate, inkqubo ye-pore kunye ne-cavity eyenziwe yi-tetrahedron ye-silico-oxygen okanye i-alumino-aluminium tetrahedron edityaniswe ziibhondi ze-oxygen bridge. Inokuzinza okuphezulu kobushushu, ukuzinza kobushushu bamanzi kunye nokumelana ne-asidi kunye ne-alkali
