Method for producing vanadium traps by means of impregnation and resulting vanadium trap
The invention relates to a method for preparing a chemical composition obtained by co-impregnating water-soluble salts Ba/Mg and phosphoric acid H3PO4 on boehmite alumina which has been calcined in the presence of water vapor. Said chemical composition is used as an additive in the catalytic crackin...

| description | The invention relates to a method for preparing a chemical composition obtained by co-impregnating water-soluble salts Ba/Mg and phosphoric acid H3PO4 on boehmite alumina which has been calcined in the presence of water vapor. Said chemical composition is used as an additive in the catalytic cracking process in order to capture metals originating from the charge, particularly vanadium, in the presence of SO2 and thus to protect the activity and selectivity of the catalytic cracking catalyst. |
