Abstract
A method for the continuous production of an improved diesel fuel, having enhanced ignition characteristics, more particularly with a greater electric conductivity, enhanced cetane numbers and lubricity and with greater percentage of complete combustion, resulting in less soot production and NOx reduction at the same time in an internal combustion diesel engine, breaking the tradeoff in the emission of those two pollutants from an internal combustion diesel engine.
Claims17
A process for production of an improved diesel fuel, the process comprising the steps of:
- a) mixing and homogenizing the following streams:
- a first stream (SD) of a petroleum-derived, ultra-low diesel fuel;
- a second stream (S1) of a first additive comprising a mixture of ethoxylated esters which is used as surfactant;
- a third stream (S2) comprising a second additive comprising an aqueous emulsion containing a mixture of water-soluble surfactants and cyclic-aromatic hydrocarbons in order to produce a mixed and homogenized stream comprising SD+S1+S2;
- and
- b) converting the petroleum derived ultra-low diesel fuel contained in the mixed and homogenized stream obtained in step a) into a bipolar diesel fuel by submitting the mixed and homogenized stream to controlled cavitation inside a Shock Power Reactor having a rotor, in order to obtain the improved diesel fuel;
- wherein the mixed and homogenized stream comprises 95.5 to 97.6% by mass of the petroleum-derived, ultra-low diesel fuel.
An improved diesel fuel,
- wherein the improved diesel fuel is a bipolar diesel fuel having an electrical conductivity of more than 1000 times compared with the electrical conductivity of regular diesel fuel, a lubricity parameter of approximately 0.300 mm, an aromatic content greater than 0, and
- wherein the improved fuel when burned by a diesel combustion engine reduces the production of soot by more than 30% and reduces the production of NOx with a fuel penalty of from 0 to 3%.
