Embodiment 1
[0031] 1) Boil the cordierite honeycomb ceramics in 3mol / L hydrochloric acid, and keep boiling for 1 hour, then take out the honeycomb ceramics, wash them with distilled water, and fully dry them;
[0032] 2) Weigh 0.501g palladium nitrate dihydrate, 2g gamma-Al 2 o 3 , 4g polyethylene glycol 400, dissolve palladium nitrate dihydrate in 10ml water and add γ-Al 2 o 3 and Polyethylene Glycol 400, after being stirred evenly, the slurry is obtained;
[0033] 3) Immerse the honeycomb ceramics obtained in step 1) in the slurry obtained in step 2) for 1 min, take out the honeycomb ceramics, blow off the excess slurry with a blower so that the slurry is evenly coated on the honeycomb ceramics, and place the honeycomb ceramics in Fully dried in a drying oven, and then calcined at 450°C for 5 hours to obtain a catalyst precursor;
[0034] 4) The catalyst precursor obtained in step 3) is completely reduced with coal gas to obtain the catalyst.
[0035] Add the catalyst of this examp...
