Abstract
The present invention relates to a method for obtaining a plurality of combustible gases from a rock and producing energy using the combustible gases. The method allows the utilization of shale rocks which are practically just waste, and enables producing a plurality of hydrocarbons in an aerobic condition. Obtaining combustible gases using the method disclosed in the present invention reduces the usage of fossil fuels. Thus, it is more environment-friendly compared to using fuels.

DETAILED DESCRIPTION OF THE INVENTION
(7) The inventive method of obtaining combustible gases from rocks, for the production of energy essentially comprises the very basic steps of; milling the components, reacting the milled components with oxalic acid, obtaining hydrocarbons such as methane, ethane, propane, butane, pentane, hexane, and their iso forms (isomers), as a result of this reaction, in an aerobic environment.
(8) In the inventive method, those shale rocks that emerge as a waste and have to be removed in any open or closed coal mining due to their very low calorific value for energy production hence increase the cost of coal mining, are especially preferred. In the present invention, the components that can be used include, but are not limited to any of shale rocks, sub-bituminous coal, half-bituminous coal, bituminous shale, kerogenous shale, bituminous schist rocks, marl, tar sand, oil sand, chitin, lignin, Sahara dust, desert dust, and combination thereof. In the remaining parts of the specifications, compounds comprising one, multiple or all of the above-mentioned components will simply be named components. The milled components are then reacted with oxalic acid. As the result of this reaction, hydrocarbons such as methane, ethane, propane, butane, pentane, hexane, and their iso forms, are produced in an aerobic environment. Hydrocarbons are thus obtained in the oxygenated environment.
(9) The station data, carried out under the framework of atmospheric greenhouse gas monitoring programs and open to the public, show that atmospheric carbon dioxide (CO2) and methane (CH4) have changed at the same time in the Sahara dust transport processes.
(10) For example, the change in CO.sub.2 and CH.sub.4, at Mace Head (MHD) atmospheric monitoring station which is located in the west of Ireland, as of February 2014, are shown (
(11) The work we have done explains why and how the changes that occur in the process of Saharan dust transfer in the atmosphere create the CO.sub.2 in the cloud.
(12) These changes have been studied via the monitoring station that has been established at Ankara.
(13) As we know the reason of the cause of the formation of CO.sub.2 in the atmosphere, we have developed a hypothesis suggesting that the CH.sub.4 which shows a simultaneous and totally parallel changes as CO.sub.2, are being formed at the same source. However, the known or accepted fact in the scientific world is that methane can only be formed purely and simply in an anaerobic environment. However, as shown in
(14) Our studies regarding the inventive application have picked up steam upon the assumption that the phenomenon which caused the said parallel change is the dusts that raised from the Sahara Desert. The basis of our studies starts with the interaction of oxalate with clay mineral, which is formed by the interaction of desert dust with cloud water during the dust transfer process. As a result of this reaction, Iron Oxalate is formed, and through a decarboxylation reaction, assisted by solar energy, CO.sub.2 is formed. This formation has been numerously measured during the process of dust transport. It has been shown by that this formation is triggered by the oxalate, which is produced by the bacteria and fungi, upon their contact with the water inside the cloud droplet, during the long-distance transfer process of the dusts stemming from the desert. As a proof to this, it is shown that the said oxalate, and thus the decarboxylation products cannot be obtained using the specimens that are sterilized using Co.sup.60 gamma radiation.
(15) The formation of methane, which shows parallel change to the carbon dioxide, in aerobic conditions directed us to investigating, in detail, the materials that are present in the soil. In our examinations, we have seen that the outer walls of the fungi are made of chitin. When the molecular structure of chitin (
(16) The experiments have been carried out with desert dust and water mixture. In order to eliminate the atmospheric contribution, the experiments have been carried out in controlled conditions which are named headspace. The gas obtained as a result of the experiments was tested with pure methane gas at 1 and 15 ppmv.
(17) As can be seen from the chromatogram in
(18) These experiments are later repeated using shale rocks and oxalate in headspace cups thus eliminating atmospheric interferences and the formation of methane, ethane, propane, buthane, pentane, hexane, and their isomers has been detected. Producing hydrocarbons such as methane, ethane, propane, buthane, pentane, hexane, and their isomers by reacting the shale rocks with the oxalic acid, has been neither known, nor used until now. This method provides an unexpected effect as it is unexpected for the hydrocarbons to form in an aerobic environment.
(19) In order to identify the obtained gases, they have been simply compared with the composition of the household tube gases. The chromatogram of household tube gas (
(20) In the performed experiments, it has also been investigated at which pH value should the used oxalic acid be. Even though it has been observed that the reaction takes place at every concentration of oxalic acid having a pH value below 7, it has been understood that the most suitable pH value is below 2.
(21) It has also been observed in the conducted experiments that the mixture of ground shale rocks and oxalic acid can be realized at any ratio, and at any temperature.
(22) Also, experiments using sub-bituminous coal, half-bituminous coal, bituminous shale, kerogenous shale, bituminous schist rocks, marl, tar sand, oil sand, chitin, lignin, Sahara dust, desert dust materials have been conducted experiments formation of hydrocarbons is observed when any of these materials are used.
(23) The flammable gases obtained by the method of the invention can then be burned to produce heat and thus these gases can be used to generate energy.
(24) These gases can be used especially in power plants using heat for producing electricity, such as natural gas cycle plants, coal power plants etc. By this way, the fossil fuels, which are used in the plants, can be substituted with a renewable source, and thus a more environmentally friendly energy production method is achieved.
(25) The produced gases can also be used as fuel in internal combustion engines.
(26) These gases can be used in all internal combustion or external combustion heat cycles.
(27) The combustible gases obtained by the inventive method can be used in heat cycles by taking them directly into a combustion chamber or can also be stored for later usage.
(28) It is also possible for the gases having longer chains, which are obtained by the inventive method, to be converted to other petrochemical raw materials using chemical techniques.
