1) as a non-limiting example, if the acetylene in the hydrocarbon-containing mixture for processing consists of 20%, then, indifferent gas
The content of body can be from 20% to 80%.
As it is used herein, the implication that " noble gases " are known in the art with it, and including (example at room temperature
Such as 20 DEG C) composition that exists with gaseous state, it will not be with hydrocarbon reaction or burning, and the implication being also known in the art including it.
The hydrocarbon-containing mixture of the process can also be anhydrous.As it is used herein, term " anhydrous " can be indicated without detectable
The water or vapor of amount, but may also comprise based on the water less than 1% of percentage by weight, the water less than 0.5%, less than 0.1%
Water, the water less than 0.01%, the water or less than 0.0001% water less than 0.001%.
The hydrocarbon-containing mixture of the process can also be stored or processed in liquid form under stress.Due to the liquid of light hydrocarbon
Change generally occur under high pressure, be only for it is possible in theory because the hydrocarbon-containing mixture of process described herein is under high pressure
It is unexpectedly stable.The hydrocarbon-containing mixture of the process of the liquid can be free of solvent (for example, acetone and dimethylformamide),
Can be stored in hollow container (i.e. a kind of container --- the Agamassan being such as disposed therein without porous matrix), or
Both of which has.
The hydrocarbon-containing mixture of the process can be stablized more than 1 day under the pressure of 25psig.This is and conventional acetylene gas
Substantial differences, the conventional acetylene gas can explode under the pressure higher than 15psig.This unique attribute allows the place
The hydrocarbon-containing mixture (i) of reason is stored in liquid form and is not dissolved in solvent, and (ii) is not having acetylene gas mesh
It is transported, stores and uses in the front necessary conventional can without porous media.When the pressure for being exposed to more than 15psig when
Wait, the acetylene gas produced by conventional method can occur the blast with destructive result.Therefore, when the conventional acetylene gas of process
When, it is necessary to multinomial preventive measure is taken, and needs special equipment.Unlike this, the hydrocarbon-containing mixture of process described herein
Even if higher than 20psig, 25psig, 30psig, 30psig or or even the pressure of 40psig under still keep stable, even and if
Place at least 1 hour under these elevated pressure, at least 6 hours, at least 12 hours, at least one day, at least one week, or at least
Still keep within one month stable.As it is used herein, " stable " hydrocarbon-containing mixture is exposed in long-time as above
Will not explode when under high pressure.This causes the hydrocarbon-containing mixture to be used in widely application, while keeping high
Energy content.
Compared to the CO2 emission factor that the per unit energy of natural gas is exported, the hydrocarbon-containing mixture energy of the process
The CO2 emission factor with the per unit energy output for reducing.The emission factor ratio of untreated hydrocarbon-containing mixture
The emission factor of natural gas wants high about 0.000025 times.But, the energy output of untreated hydrocarbon-containing mixture is more than day
So energy output of gas.The energy content of the untreated hydrocarbon-containing mixture can be by addition noble gases or/and nitrogen
To reduce.
In certain embodiments, the emission factor of the hydrocarbon-containing mixture of the process will be as little as than the emission factor of natural gas
Few 15%.In certain embodiments, the emission factor of the hydrocarbon-containing mixture of the process will be as little as than the emission factor of natural gas
Few 20%, or it is as little as fewer by 25% than the emission factor of natural gas or as little as fewer by 30% than the emission factor of natural gas, or ratio
The emission factor of natural gas will as little as lack 35%, or as little as fewer by 40% than the emission factor of natural gas, or than the row of natural gas
Putting the factor will as little as lack 45%.
The hydrocarbon-containing mixture of the process can be used for the rule of the carbon dioxide and natural gas of unit energy output for producing
Generalized compares.In view of identical combustion process, compared to natural gas, the hydrocarbon-containing mixture of the process can produce less product
The carbon dioxide of raw per unit energy.As a non-limiting example, if natural gas discharge 100lb/ft3Dioxy
Change carbon, then untreated hydrocarbon-containing mixture can discharge 100.0020lb/ft3Carbon dioxide.It is described untreated hydrocarbonaceous mixed
The energy content of compound can be higher than 1,100BTU/ft3, and the energy content of natural gas can be less than the untreated hydrocarbon-containing mixture
Energy content.By the nitrogen or noble gases that add 35-50%, the carbon dioxide discharged by the hydrocarbon-containing mixture for processing
Amount will reduce 35-50%.Therefore, compared to natural gas, the greenhouse gases of the hydrocarbon-containing mixture of the process in per unit heat energy
Carbon dioxide aspect is subjected to substantive reduction.
The hydrocarbon-containing mixture of the process can surprisingly be used as the direct succedaneum of natural gas.In standard temperature and
Under pressure, the energy content of the untreated hydrocarbon-containing mixture can be at least 1,100BTU/ft3.The release of this energy and day
So gas phase matches in excellence or beauty, but hydrocarbon-containing mixture is a kind of improvement, because it can be formed in situ, rather than it is a kind of from ground extract from
Right resource.Depending on the concrete composition of the untreated hydrocarbon-containing mixture, add to the untreated hydrocarbon-containing mixture
35% nitrogen can be that the hydrocarbon-containing mixture for processing produces 825-1073BTU/ft3Energy output.Similarly, depending on institute
The concrete composition of untreated hydrocarbon-containing mixture is stated, the nitrogen to the untreated hydrocarbon-containing mixture addition 50% can be place
The hydrocarbon-containing mixture of reason produces 521-678BTU/ft3Energy output.
