Synthetic zeolite, in particular for catalytic hydroisomerization of higher paraffins

摘要: The inventive ZSM-12-type zeolite, in particular for hydroisomerization of higher paraffins has a primary crystalline size ≤0.1νm and specific volume which ranges from 30 to 200 mm3/g is determined by mercury porosimetry at maximum pressure 4000 bars within pore dimensions ranging 4 10 nm. Said zeolite made synthetic gel compound containing an aluminium source, silicic acid precipitates as silica TEA* matrix source alkali metal and/or earth M ions with n valence. In said compound, molar ration H2O/SiO2 selected between 5 15. A catalyst the use thereof are also disclosed.
