ZSM-5 Zeolite Molecular Sieve SiO2/Al2O3 Mole Ratio 15-1000
ZSM-5 type zeolite,belonging to high-silica zeolite and having a Si/Al ratio of up to 1000 and above,also shows the hydrophobic characteristic.The structural feature of such a zeolite is that the vertical and horizontal parts are crystalline aluminosilicate composed of 10-membered channel.The basic structure is composed of eight 5-membered rings,which has channels only and is without cage-free cavities.ZSM-5 has two sets of cross channels,one of which is straight,and the other one is shown in zig-zag type and vertical to each other.The channel is shown in the form of an ellipse,and the window diameter thereof is 0.55 to 0.60nm.As the reaction space is similar to the shape of the access,the zeolite has a shape selection effect to the reactants and products.Moreover,ZSM-5 is a good raw material of selective catalyst due to the harmonious structure and hydrothermal stability.
ZSM-5 type zeolite is widely applied to petrochemical processing industries,applied to the fluidifying,catalyzing and cracking process as an assistant for producing more propylene and liquefied gas,and improving the octane number of the gasoline. In addition,the zeolite can be applied to the production of ethybenzene ,xylene,phenol,pyridine,etc.
The varieties for the typical products of ZSM-5 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:
The ZSM-5 type zeolite produced by means of a template agent free hydrothermal crystallization method is featured with high relative crystallinity,wherein the relative crystallinity is no less than 90%,the SiO2/Al2O3 molar ration is no less than 25,and the Na2O is no more than 0.1%.
