Examples
Embodiment 1
[0032] Mix 35.00g of kaolin powder and 33.00g of iron-containing ore (both 90 mesh) evenly, then use a vulcanizing agent for vulcanization. The vulcanizing agent is carbon disulfide, and then dry-mix with 32.00g of 90-mesh zinc oxide powder, stir well, and mix Catalyst 1 was obtained after homogenization.
Embodiment 2
[0034] Under stirring conditions, 0.25mol La (NO 3 ) 3 Dissolve in 100 mL of water, add citric acid and stir to dissolve; then add 0.5 mol Fe(NO) 3 ) 3 , and then add 18 g of sodium polyacrylate, continue to stir for 30 minutes to obtain a reaction solution, which is calcined and ground to obtain micro-mesoporous lanthanum ferrite.
[0035] After roasting kaolin powder and iron-containing ore powder at 430℃, mix 40.00g kaolin powder and 30.00g iron-containing ore (both 60 mesh) evenly, and then use vulcanizing agent for vulcanization treatment. The vulcanizing agent is sulfur powder, 5g After vulcanization, the micro-mesoporous lanthanum ferrite powder was dry-mixed with 30.00 g of zinc oxide powder containing zinc-aluminum spinel structure, and then mixed with kaolin powder and iron-containing ore powder, fully stirred, and mixed uniformly to obtain catalyst 2.
Embodiment 3
[0037] After roasting kaolin powder and iron-containing ore powder at 450℃, mix 20.00g kaolin powder and 55.00g iron-containing ore (both 80 mesh) evenly, and then use vulcanizing agent for vulcanization treatment. The vulcanizing agent is carbon disulfide, 25.00g Zinc oxide powder containing zinc-aluminum spinel structure was mixed with 5g of waste ZSM-5, and then dry-mixed with 7g of vulcanized micro-mesoporous lanthanum ferrite powder, mixed uniformly, and then mixed with kaolin powder and iron-containing ore mixture uniformly , to obtain catalyst 3.
