Solution, therefore the soil purified does not lose intrinsic physical property.Previous thermal decomposition manner, due to decomposing organic matter ingredient, with
The present invention distinguishes.
The residence time that the soil of coating organic pollution materials is trapped in carbide furnace is possible to particularly important.But with regard to carbon
For changing stove, type is very various, and the parameter that heat is applied to soil etc with direct, indirect or its hybrid mode is more, therefore
It is difficult to the specific residence time appropriate.Therefore, optimal conditions can be used in the above-mentioned residence time within the scope of the present invention.But
It is that, since the embodiment of the present invention is applicable in the carbide furnace of direct flaming mode, the above-mentioned residence time can set suitable for straight
Connect the optimal conditions of flaming mode.
The method for preparing oxygenated hydrocarbon of the embodiment of the present invention will be heated first and be transformed to that carbon occurs before gaseous state
The contaminated soil of the organic pollution materials pollution of change is put into carbide furnace.Later, it is set as the carburizing temperature of above-mentioned carbide furnace

Sample has used the soil 200000ppm by Middle East production and Southeast Asia wind-producingization crude oil pollution, and functional group passes through described above
Analytic approach confirms.If under suitable condition heating organic pollution materials (organic matter), above-mentioned oxygenated hydrocarbon by gasification and
Thermal decomposition, with gas form be released to outside or according to dehydrogenation (dehydrogenation) and condensation (condensation) it is anti-
It answers, is carbonized the amorphous composite high-molecular substance for high molecular weight.That is, the carbonization of the so-called present invention refers in condition appropriate
Lower heating organic matter becomes the process of the amorphous carbon rich in carbon by thermal decomposition process.
At this point, amorphous carbon interconversion rate (%), which is in whole organic matter 100g, is released but is converted with gas form
