Description

PROCEDURE OF OBTAINING AUTOMOTIVE FUELS AND THE MODIFIED FUELS OBTAINED BY MEANS OF THIS PROCEDURE
The present patent refers to a procedure of obtaining automotive fuels and the modified fuels obtained by means of this procedure.
The main objectives related to the petroleum refining consist in obtaining fuels as gasoline or Diesel that would grant an optimum operation of the spark ignition engines or the compression ignition engines, respectively, and that would also contribute to the pollution phenomenon generated by exhaust gases decreasing, namely by means of lowering-down the smoke index, the CO, CO2, hydrocarbon and NOx emissions.
The already known procedures used for hydrocarbons process in view of obtaining automotive fuels consist in hydrogen treatment of petroleum fractions.
Thus, a procedure of obtaining Diesel-type fuels consists in treating the raw material resulted from the cracking process with hydrogen at high pressures and temperatures, in the presence of some catalytic agents. The first catalytic agent contains a metal belonging to the IV- th group and a metal belonging to the VIII-th group, placed on a non-acid support, and the second catalytic agent contains a metal belonging to the VI-th group and a metal belonging to the VII-th group, placed on a non-acid support (US Patent No. 5.865.985).
As concerns another procedure, further to treating the raw material with hydrogen in the presence of a catalytic agent of the large mash molecular sieve-type, having a "faujasita"-type structure and an alpha acidity less than 1, that contains a noble metal belonging to the VIII-th group, which favors the hydrogenation/hydro-cracking process of the aromatic and naphthenic compounds from the raw materials, there shall be obtained another diesel fuel with a superior Cetane number (US Patent No. 6.210.563).
The gasoline obtaining procedure consists in the hydrotreatment process of the mean fraction separated from natural gasoline by fractioning method. Thus, a gasoline with a low content of benzene will result, due to benzene transforming into cyclohexane which in turn may be subsequently isomerized in view of improving its octane number (US Patent No. 6.855.853).
A procedure to obtaining a low sulphur content gasoline consists in the diolefine selective hydrogenation process under special operating conditions by which the sulphur compounds that are present in the raw material are partially converted into heavier compounds while, the separation of the heavier fraction rich in sulphur and its hydrodesulphuration process being made on a specific catalytic agent (UD Patent No. 7.052.598). AU these procedures are generally carried out at high temperatures and pressures within installations which involved large investments, and relatively high hydrogen consumption.
It is already known that an oxyhydrogen gas has been obtained based on the controlled dissociation, in electromagnetic field, of an alkaline aqueous solution. This gas, further on namely as "the HHO oxyhydrogen gas" is a mixture of 63 - 67% hydrogen and 30 — 35% oxygen. The special qualities of this gas result from its capability to react with materials of any nature, which justifies the efforts to promote it to different industrial applications (US Patent No. 6.689.258 Bl and the request published at the international level under No. WO2005076767 A3, Mr. Dennis J. Klein being the author of both of them).
The technical problem the invention solves consists in the automotive fuels physico- chemical properties improving with simultaneously diminishing of exhaust gas pollution level resulted when using these fuels.
The procedure of obtaining gas, as per the invention, consists in the hydrocarbon fraction contact treatment with HHO oxyhydrogen gas by its direct bubbling, either in the presence or in the absence of catalytic agents, in a discontinuous sequence, or in a continuous sequence, with or without re-circulating the gaseous mixture, in a temperature range of 20 to 100 Celsius degrees, and a pressure range of 1 to 20 atmospheres, for as long as 0.2 to 8 hours.
The gas obtained further to applying the invention procedure has a higher by 2% hydrogen and~δxygen content and assures the cutting-down" of"smσke-and particulate emissions.
As a consequence of hydrocarbons treating by the HHO oxyhydrogen gas is assured the improvement of the fuel burning characteristics as well as the decreasing of the burned gas pollution due to the HHO oxyhydrogen gas composition, which, according to the invention, enriches the treated fuel both in hydrogen reactive status, and in- oxygen, as well.
This way, further to treating gasoline with the HHO oxyhydrogen gas, one can noticed the characteristics modification (density, boiling curve, chemical composition, and IR spectrum). The improvement of the gasoline characteristics that have been modified further to submitting it to the HHO oxyhydrogen gas treatment, is evident by what is concerned its chemical composition, the carbon, hydrogen and oxygen contents.
The procedure of obtaining gas by HHO oxyhydrogen gas treatment, in accordance with the invention, has the following advantages:
- it reduces the CO and CO2 emissions;
- it reduces the hydrocarbon emissions; it reduces the smoke number. There are submitted 4 examples of achieving the procedure as per the invention, also in connection with the Figures that represent:
Fig. 1 - the initial Diesel fuel composition, and its composition after the treatment with the HHO oxyhydrogen mixture by means of GC_MS;
Fig. 2 - the smoke emissions while testing the initial Diesel fuel, and the smoke emissions after the treatment with the HHO oxyhydrogen gas in accordance with example 1;
Fig. 3 - the particulate emissions while testing the initial Diesel fuel, and the particulate emissions after the treatment with the HHO oxyhydrogen gas in accordance with example 1. ■
Example 1
A balloon that has been provided with a frit bubbling system, a pressure and HHO gas discharge control and adjustment device, shall be fed with 350 ml of Euro 3+ Diesel fuel. The HHO gas discharge shall be adjusted at 3.5 1/h, and the bubbling process shall be maintained at 25 Celsius degrees temperature and at atmospheric pressure in the case of open vessel, for as long as 30 minutes. The reaction product shall be then analyzed by determining the water content, the ash content" "as well as the content in the following elementsrcarbon, hydrogen and oxygen.
Table 1 summarizes data that are characteristics of the initial fuels and of the final fuels after the HHO oxyhydrogen gas treatment with.

Example 2
A metallic autoclave that has been provided with a frit bubbling system, a pressure and HHO gas discharge control and adjustment device, shall be fed with 350 ml of Euro 3+ Diesel fuel. The HHO gas discharge shall be adjusted at 3.5 1/h, and the bubbling process shall be maintained at 45 Celsius degrees temperature, and at 10 atmospheres pressure for as long as 30 minutes.
The reaction product is then analyzed by determining the water content, the ash content, as well as the content in the following elements: carbon, hydrogen and oxygen (see Table 1). One can be noticed a decrease in the carbon content of the Diesel fuel correlated with an increase in the hydrogen and oxygen content.
Example 3
A balloon that has been provided with a frit bubbling system, a pressure and HHO gas discharge control and adjustment device, shall be fed with 350 ml of gasoline. The HHO gas discharge shall be adjusted at 3.5 1/h, and the bubbling process shall be maintained at 25 Celsius degrees temperature and at atmospheric pressure in the case of open vessel for as long as 30 minutes. The reaction product shall be then analyzed by determining the water content, the density, the chemical composition and the content in carbon, hydrogen and oxygen (see Table 1). The chemical composition of the mixture has been determined by means of the GC method. One can noticed a decrease in the carbon content of gasoline correlated with an increase in the hydrogen and oxygen content, as well as a modification of the chemical composition. Thus, the content in isopenthane, the content in the C4-C6 fraction and in the aromatic hydrocarbons "increases, and the content in the C8+ fraction decreasesτwhrlei:he content in ethers remains the same.
Example 4
The modified Diesel fuel testing as per Example 1 has been carried out on an engine test bench equipped with a direct injection diesel engine, 4 cylinders in line and a 17.5:1 compression ratio. The test bed is also provided with a speed transducer, a mass fuel consumption equipment, a smokemeter and a particles emission analyzer. The results related to the engine fueling behavior are presented in Figures 2 and 3. It shall be noticed that the smoke numbers and the particulate emissions decreased comparing against the situation when normal diesel fuel was used; however, the decrease values are more obvious at lower outputs of the engine.
