Ukuvula izisombululo eziPhezulu zeMolekyuli: Ii-Zeolite ezilungiselelwe ukuGqwesa kweShishini

Njengomqambi okhokelayo kwitekhnoloji ye-sieve ye-molekyuli, sihambisa izisombululo ze-zeolite ezisebenza ngokwezifiso zezicelo ezibalulekileyo ekwahlukaneni kwegesi, iikhemikhali zepetroli, ukulungiswa kokusingqongileyo, kunye ne-catalysis.

Iimveliso ezingundoqo kunye nezicelo:

Uhlobo lwe-A (3A, 4A, 5A): I-micropores efanayo, i-adsorption ephezulu, ukuzinza kwe-thermal. Izicelo: Ukomisa igesi (3A: ethylene / propylene; 4A: igesi yendalo / iifriji), ukuhlukana kwe-alkane (5A), ukuveliswa kwe-oksijini (5A), izongezo ze-detergent (4A).

13X Uthotho:

I-13X: I-adsorption ephezulu ye-H₂O, i-CO₂, i-sulfides. Izicelo: Ukucoca umoya, ukuchithwa kwegesi.

LSX: I-SAR esezantsi, i-N₂ adsorption ephezulu. Izicelo: Ukuveliswa kweoksijini (PSA/VSA).

K-LSX: Uphuculo lwe-N₂ yokukhetha. Izicelo: Iinkqubo ze-oksijini zonyango/zemveliso.

I-ZSM-Series (ZSM-5, ZSM-22, ZSM-23, ZSM-48): I-1D / 2D pores, i-acidity ephezulu, i-catalysis yokukhetha imilo. Izicelo: Ukucocwa kweFCC, i-isomerization (i-lubricants/diesel), unyango lwe-VOCs, i-olefin processing, ukuphuculwa kwe-biomass.

IiZeolite zeCatalytic ezikwinqanaba eliphezulu:

I-Beta (BEA): SAR 10-100, ≥400 m²/g, 3D 12-ring pores. Ukusetyenziswa: i-FCC, i-hydrocracking, i-alkylation enkulu-molekyuli / isomerization.

Y (FAU): SAR 5-150, ≥600 m²/g, iipores ezinkulu kakhulu. Izicelo: I-FCC catalysts, i-hydrocracking, i-oyile enzima, i-desulfurization.

I-Amorphous Silica-Alumina (ASA): I-non-crystalline, i-acidity e-tunwable, ≥300 m²/g. Izicelo: I-FCC catalyst matrix, inkxaso ye-hydrotreating, i-adsorption yenkunkuma.

Ukwenziwa ngokwezifiso: Sisebenza ngokukhethekileyo ekulungiseni iisefu zemolekyuli (ubungakanani bepore, iSAR, ukutshintshiselana ngeion, iasidi) ukuphucula ukusebenza kwe-adsorption, catalysis, okanye ukwahlula, ukusuka kwiR&D ukuya kwisikali seshishini. Ukuqinisekiswa kokucoceka okuphezulu, uzinzo, kunye nokusebenza kakuhle.

Ngathi:Siqhuba iteknoloji ye-molecular sieve ukwenzela ukugcinwa kunye nokusebenza ngokufanelekileyo kwezoshishino. Qhagamshelana nathi ukwandisa iinkqubo zakho ngee-zeolite ezilungiselelweyo.
