Smoke suppressant additives for petroleum fuels
Abstract
Abstract THE INVENTION DISCLOSED HEREIN IS A LIQUID FUEL COMPOSITION COMPRISING A LIQUID HYDROCARBON FUEL HAVING A TENDENCY TO FORM SOOT AND SMOKE ON COMBUSTION AND A METAL SALT OF AN ALKANOIC ACID, WHEREIN THE CONCENTRATION OF METAL SALT IS AT LEAST SUFFICIENT, USUALLY FROM 0.05 TO 5% BY WEIGHT, TO INHIBIT SAID TENDENCIES. ESPECIALLY SUITABLE COMPOSITIONS INCLUDE A DIESEL FUEL HAVING FROM ABOUT 0.3 TO 2% BY WEIGHT OF BARIUM 2-ETHYLHEXANOATE AND A DIESEL FUEL HAVING FROM ABOUT 3.1 TO 2% BY WEIGHT OF CALCIUM 2-ETHYLHEXANOATE ADMIXED THEREIN. FURTHER IMPROVEMENT IN SOOT AND SMOKE REDUCTION IS OBTAINED IN HYDROCARBON FUELS AND PARTICULARLY IN DIESEL FUELS, WHEN AN ETHER IS ADDITIONALLY INCORPORATED INTO THE SALT AND FUEL MIXTURE. A DIESEL FUEL HAVING FROM ABOUT 0.1 TO 0.5% BY WEIGHT OF BARIUM 2-ETHYLHEXANOATE AND FROM ABOUT 0.3 TO 0.6% BY WEIGHT OF THE MONOMETHYL ETHER OF ETHYLENE GLYCOL EXHIBITS SUBSTANITIALLY REDUCED SMOKE AND SOOT FORMING CHARACTERISTICS.
