Abstract:
Processes for manufacturing nitrogen oxide storage materials and lean NOx trap catalysts are disclosed. Also disclosed are nitrogen oxide storage material made by processes comprising barium carbonate (BaCO 3 ) and ceria (CeO 2 ) by using Ba(OH) 2  instead of most or all Ba(OOCH 3 ) 2  to reduce cost and reduce harmful byproducts. Aspects of the present invention also relate generally to lean NO x  trap (LNT) comprising nitrogen oxide storage materials.

Claim (Index 13):
A process for manufacturing a nitrogen oxide storage material, the process comprising:\n preparing a mixture of Ba(OH) 2 , CeO 2 , and H 2 O, wherein Ba(OH) 2  is present in an amount up to the maximum solubility of Ba(OH) 2  in H 2 O at the temperature of the H 2 O, and CeO 2  is present in an amount of about 1.75 to about 2.0 times the amount of Ba(OH) 2  by weight; milling the mixture for a period of time in the range of about 30 minutes to about 60 minutes to provide a milled mixture; drying the milled mixture at a temperature in the range of about 110\u00b0 C. to about 140\u00b0 C. for a period of time in the range of about 8 hours to about 18 hours to provide a dried, milled mixture; and calcining the dried, milled mixture at a temperature in the range of about 40\u00b0 C. to about 700\u00b0 C. for a period of time in the range of about 30 minutes to about 120 minutes.
