Embodiment 1
[0054] This example is used to illustrate the method for preparing a hydroisomerization catalyst provided by the present invention.
[0055] (1) the amorphous silicon aluminum of 86g (SIRAL company, ASA, specific surface area 500m 2 / g, pore volume 1.6ml / g, SiO 2 Content 40% by weight) and 74g of pseudo-boehmite (SB, uncalcined, specific surface area 233m 2 / g, pore volume 0.52ml / g) mix homogeneously, in the state of stirring, add by the nitric acid (concentration is 65% by weight, Beijing Reagent Company, chemically pure) of 2.0g, the sodium nitrate of 4.825g (Beijing Reagent Company, chemical pure) and 224g of water, and then kneaded in a mixer to form a ball, then put it into an extruder to extrude a cylindrical shape (maximum diameter is 2mm), and dried at 120°C for 4h, and roasted at 500°C for 4h, obtaining vector precursors;
[0056] (2) Put the carrier precursor into the hydrothermal device and feed air and water at 500 ° C. The feed rate of water vapor is 20% by volum...
