Abstract:
A water-immiscible organic fluid is tagged and identified by tagging the organic fluid with between about 0.25 and about 100 ppm of a marker compound having the formula: ##STR1## where the OH groups are either ortho or para to the diazo moieties, and the Xs are the same or different and are selected from C.sub.1 -C.sub.12 -alkyl, Cl, Br, F, NH.sub.2, CN, NO.sub.2, NH(C.sub.1-3 -alkyl) and N(C.sub.1-3 -alkyl).sub.2, and the fluid is identified by extracting the tagged fluid with an alkaline aqueous extractant having a pH above about 12 and containing, based on 100 parts by weight of said extractant, between about 10 and about 60 parts by weight of an organic cosolvent having the formula:R.sup.1 --O--R.sup.2 --NH.sub.2 (II)where R.sup.1 is C.sub.1 -C.sub.3 -alkyl, and R.sup.2 is C.sub.2 -C.sub.6 -alkylene.

Abstract:
Beta-carotene, chlorophyll and jojoba oil are used together as a fuel additive to enhance combustion characteristics of carbonaceous fuels. Among the observed beneficial characteristics are reductions in the level of common pollutants emitted during combustion. Ethoxylated castor oil is also used in conjunction with the beta-carotene, chlorophyll and jojoba oil to provide enhanced combustion characteristics and reductions in pollutant emissions.
