example 1
[0034] 234.3g of CL-1 powder (taken from Changling Catalyst Factory, obtained by roasting at 500°C for 4 hours is D1, its specific surface and pore distribution are listed in Table 1), Siral 40 (from Sasol Company, SiO 2 39.6%, Al 2 o 3 60.3%, XRD shows pseudo-boehmite phase) mixed with 64.2g, extruded into a trilobal strip with a circumscribed circle diameter of 1.5 mm, dried at 120°C for 4 hours, and roasted at 550°C for 3 hours to obtain carrier S1. The composition of Vector S1 is listed in Table 2.
example 2
[0038] First mix 73.0 g of SB powder (product of Sasol Company) with 56.3 g of CL-1 powder (same as Example 1) (the alumina obtained by roasting at 550° C. for 4 hours is D2, and its specific surface and pore distribution are listed in Table 1) , then with Siral 40 (same example 1) 227.8g, beta molecular sieve (SiO 2 / Al 2 o 3 =13.7, Changling Oil Refinery Catalyst Factory) 38.0g mixed, extruded into a trilobal bar with a circumscribed circle diameter of 1.5 mm, the wet bar was dried at 120°C for 4 hours, and roasted at 550°C for 3 hours to obtain carrier S2, carrier S2 The composition is listed in Table 2.
example 3
[0040] CL-1 (same as Example 1) 50.0g+SX powder 66.7g (the alumina obtained by roasting at 550°C for 4 hours is D3, and its specific surface and pore distribution are listed in Table 1) powder 187.5g, Siral 40 ( With example 1) 101.2g, USY molecular sieve (unit cell constant 2.453nm, crystallinity 76.2%, Na 2 O 0.33%, Changling Refinery Catalyst Factory product) 49.4g mixed, extruded into a trilobal bar with a circumscribed circle diameter of 1.5 mm, the wet bar was dried at 120°C for 4 hours, and roasted at 500°C for 3 hours to obtain carrier S3, the carrier The composition of S3 is listed in Table 2.
