从China供应商批发进口Beta Zeolite î² Molecular Sieve For Catalyst — FOB条款

Beta Zeolite β Molecular Sieve For Catalyst Beta zeolite,having a unique three-dimensional 12-membered ring cross channel structure,is composed by mixing two polycrystals which are closely related to each other in the structure,and the two polycrystals are composed of the tetrahedral structure units which are symmetric based on the same center and arranged according to the layer.The two structures are composed of the tertiary structure units(TBU)which are symmetric based on the same center,wherein these TBUs are arranged in layer and subsequently connected in the form of left hand and right hand,This connection causes the twist along the channel of the direction C. Beta zeolite shows an excellent catalytic performance in catalytic cracking,hydrocracking,hydroisomerization,hydrodewaxing,aromatics alkylation,olefin hydration,olefin etherification and other petroleum refining and petrochemical processes. The varieties for the typical products of Beta Zeolite produced by JiuLong Chemical Co.,Ltd.are listed as follows,and the other products of this series also can be produced according to the requirements of the user: Detailed Product Description SiO2/Al2O3: 40 Color: White Powder Cation: Sodium SiO2/Al203: 25 SO4: 0.4 Cl-: 90ppm D50: 7um FCC catalyst , Beta Zeolite,Zeolite Beta,Beta Molecular Sieve SiO2/Al2O3 Mole Ratio: 25-40 Nominal Cation Form: Sodium/Hydrogen Na2O Weight %: 0.1 Surface Area, m2/g: 540 Zeolite beta β molecular sieves have three mutually intersecting 12-ring channels, it is only 12 yuan a three-dimensional pore structure of zeolite ring. β zeolite having high hydrocracking, hydroisomerization catalytic activity and adsorption capacity of linear paraffins, and good resistance to sulfur and nitrogen poisoning. It can be used in the petrochemical industry of benzene with propylene olefin system cumene, cumene metathesis diisopropylbenzene, toluene Isopropylation, aromatics alkylation, transalkylation diisopropylbenzene, propylene ether, methanol aryl structured, propylene oxide and acetic ether of phenol methylation, methylation of aniline, toluene transalkylation preparation of cumene and toluene disproportionation and transalkylation reaction with a catalyst such. β-type USY zeolite used in conjunction with the increase of the octane number of gasoline. In the fine chemical industry, β zeolite has excellent activity and selectivity in the dehydration deamination.
