MIXED ORGANOMETALLIC COMPOSITIONS COMPRISING ELEMENTS OF IRON GROUPS AND LANTHANIDES, PROCESS FOR THE PREPARATION AND APPLICATION OF SAID COMPOSITIONS AS ADDITIVES FOR FUELS OR FUELS

摘要

THE INVENTION RELATES TO MIXED ORGANOMETALLIC COMPOSITIONS COMPRISING SALTS OF ORGANIC ACIDS OF AT LEAST ONE IRON GROUP METAL AND AT LEAST ONE LANTHANIDE GROUP METAL. /P P IN THESE COMPOSITIONS TOTAL NUMBER OF METAL ATOMS AT NUMBER OF ORGANIC ACID EQUIVALENTS IS GREATER THAN 13 AND, PREFERABLY, GREATER THAN 3. /P P THESE COMPOSITIONS CAN BE USED AS ADDITIVES FOR FUELS OR FUELS.
