<p>Fuel additive comprises hydrocarbon, acidic meta-, pyro- or ortho-phosphate in form of acidic alkali salt, 8-48C (un)saturated fatty acid ester and/or ethoxylated 8-48C fatty acid ester, and/or propoxylated 8-48C fatty acid ester, ethoxylated 8-45C (un)saturated fatty acid ester, polyamine containing basic nitrogen (0.1-6) and/or ethoxylated polyamine, and/or fatty acid diethanol amide and/or alkyl amine. Fuel additive with reduced emission and modifying the surface, comprises 80-99.5 volume% of hydrocarbon boiling at 45-405[deg]C, 10->4>-2 wt.% of acidic meta-, pyro- or ortho- phosphate in the form of an acidic alkali salt, 0.1-5.5 volume% of 8-48C (un)saturated fatty acid ester preferably polyglycerol ester or their mixture, and/or 8-48C ethoxylated fatty acid ester, preferably polyglycerol ester or their mixture having 3-11 ethylene oxide (EO) units and/or 8-48C propoxylated fatty acid ester, preferably polyglycerol ester or their mixture having 2-11 propylene oxide (PO) units, 0.1-18 volume% of 8-45 ethoxylated (un)saturated fatty acid ester preferably polyglycol ester having 4-15 EO units, and 0.1-6 volume% of polyamine containing basic nitrogen and/or ethoxylated polyamine containing at least 2 basic nitrogen, and/or fatty acid diethanol amide and/or alkyl amine having 1-5 amino groups. The fuel additive has reduced specific energy consumption, ensuring increased efficiency of the equipment to be used for explosion engines, turbines heated by gaseous or liquid hydrocarbon as well as for every stoker heated by fossil combustible. Independent claims are also included for the following: (1) process to reduce emission of explosion engines, turbines and to reduce the specific energy consumption and ensure increased efficiency of the equipment to be used with simultaneous surface protection of the soot, which involves adding an additive to the soot; and (2) preparation of fuel additive which involves admixing hydrocarbon boiling at 45-405[deg]C (in volume%) (80-99.5), acidic meta, pyro or ortho phosphate in the form of an acidic alkali salt (10->4>-2 wt.%), 8-48C (un)saturated fatty acid ester preferably polyglycerol ester or their mixture, and/or 8-48C ethoxylated fatty acid ester, preferably polyglycerol ester or their mixture having 3-11 EO units and/or 8-48C propoxylated fatty acid ester, preferably polyglycerol ester or their mixture having 2-11 PO units (0.1-5.5), 8-45 ethoxylated (un)saturated fatty acid ester preferably polyglycol ester having 4-15 EO units (0.1-18), polyamine containing basic nitrogen and/or ethoxylated polyamine containing at least 2 basic nitrogen, and/or fatty acid diethanol amide and/or alkyl amine having 1-5 amino groups (0.1-6).</p> |
