Embodiment 1
[0053] Weigh 297.49g of zinc nitrate hexahydrate, 120.04g of chromium nitrate nonahydrate and 637.72g of soluble salt of aluminum nitrate nonahydrate, dissolve them in 1L of deionized water, mix well, and slowly drip ammonia water under continuous stirring to adjust the pH to 8.0, the product was aged for 2 hours, filtered and washed with 4L of water to obtain a filter cake, dried at 100°C for 16 hours, and then roasted in a muffle furnace at 600°C for 20 hours to obtain ZnCr 0.3 al 1.7 o y Carrier, the composition is shown in Table 1. Weigh 9.78g of the carrier and put it into a beaker, then weigh 0.190g of stannous chloride dihydrate and dissolve it in 10mL of hydrochloric acid solution, add the above carrier under stirring, mix well, soak at 30°C for 12 hours, and then dry at 100°C for 16 Hour namely obtains catalyst precursor, denoted as I. Weigh 0.106g of chloroplatinic acid hexahydrate and 0.472g of calcium nitrate and dissolve them in 10mL of water, adjust the pH val...
