Examples
Embodiment 1
[0027] After mixing 45.00g of kaolin and 5.00g of ammonium molybdate (both 50 mesh) evenly, vulcanize with a vulcanizing agent, the vulcanizing agent is carbon disulfide, and then dry mix with 50.00g of zinc oxide powder of 50 mesh, fully stir, and mix evenly Catalyst 1 is obtained.
Embodiment 2
[0029] Under stirring conditions, 0.25mol La(NO 3 ) 3 Dissolve in 100mL water, add citric acid and stir to dissolve; then add 0.5 mol Fe(NO 3 ) 3 , and then add 18g of sodium polyacrylate, and continue to stir for 30 minutes to obtain a reaction solution, which is roasted and ground to obtain micro-mesoporous lanthanum ferrite.
[0030] After roasting kaolin and zinc oxide at 450°C, mix 35.00g of kaolin with 10.00g of ammonium molybdate (both 80 meshes) and 2.00g of micro-mesoporous lanthanum ferrite powder, and then vulcanize with a vulcanizing agent. The vulcanizing agent is The sulfur powder was then dry-mixed with 53.00 g of nano-zinc oxide powder of 50 meshes, fully stirred, and evenly mixed to obtain Catalyst 2.
Embodiment 3
[0032] Mix 42.00g of kaolin with 8.00g of ammonium molybdate (both 70 meshes) and 6.00g of micro-mesoporous lanthanum ferrite powder, then vulcanize with a vulcanizing agent, which is carbon disulfide, and then mix with 44.00g of 50 meshes containing zinc The zinc oxide powder with aluminum spinel structure is dry mixed, fully stirred, and the catalyst 3 is obtained after uniform mixing.
