[0042] The combustion chamber 10 includes an ignition device 38, such as a spark plug. The ignition device 38 is configured to initiate a series of precisely timed combustion events. For example, each combustion event may last approximately 1 millisecond. The combustion intervals and duration may be appropriately adjusted based on the measurement conditions of the system 100. In one or more embodiments, the ignition device 38 is located at a midpoint of the combustion chamber 10. With this configuration, as particles of the reactants (flue gas, oxygen, and hydrogen) accelerate in each direction, the particles collide at each end and assemble the carbon-based nanomaterials.

[0043] The system 100 also includes a controller 30 configured to receive inputs from sensors in the system 100 and control the combustion conditions in the combustion chamber 10. In some embodiments, the controller 30 is configured to receive inputs from one or more of the flow meters 46, 56, 66, 76, the temperature sensor 18, the low pressure sensor 16, the pressure sensor 14, the high pressure sensor 12, and the pressure sensors 44, 54, 64, 74.

After combustion, the temperature within the combustion chamber 10 may be on the order of about 120° F. In some embodiments, the pressure within the combustion chamber 10 is maintained at about 5-20 psi prior to combustion. In some embodiments, the pressure within the combustion chamber 10 prior to combustion is about half the pressure after combustion, for example, about 10-40 psi, which aids in efficient conversion of carbon-based flue gases into carbon-based nanomaterial production.

[0047] In some embodiments, the system 100 is automated to provide a cost-effective method for on-site or off-site carbon-based nanomaterial production. The automated system 100 determines the mixture of each internal combustion in the chamber to produce carbon-based nanomaterials in real time. In other embodiments, the system 100 can be manually controlled by using the user interface 34.

[0048] In either embodiment, the system 100 can be configured to measure the composition of the carbon-based gas or liquid in real time. Such measurements can be obtained, for example, from measured temperature and pressure changes in the combustion chamber 10 during and after combustion. The ratio of the carbon-based gas or liquid, hydrogen, and oxygen can be precisely adjusted to achieve a consistent carbon-based nanomaterial product, or to modify the conversion of carbon from the carbon-based feedstock to carbon-based nanomaterial to increase its yield, or ideally both. After each combustion, the system 100 can fine-tune one or more parameters as needed to improve the efficiency of carbon-based nanomaterial production. Multiple combustions may be required to reach optimal combustion conditions for a given carbon-based gas or liquid. However, precise control of each input reactant allows the system 100 to operate with a wide range of carbon sources, even variable carbon sources.

[0248] Example 1 A sample carbon-based nanomaterial composition S1 was formed according to certain embodiments described herein. The sample carbon-based nanomaterial composition was formed from a gas mixture that was placed in a carbon recovery unit described herein and ignited to form the carbon-based nanomaterial composition. The composition of the gas mixture used to form the sample carbon-based nanomaterial composition S1 is summarized in Table 1 below. [Table 1]

[0249] The temperature and pressure conditions used to ignite the gas mixture to form the sample carbon-based nanomaterial composition S1 are summarized in Table 2 below. [Table 2]

[0250] 3a and 3b show transmission electron microscope (TEM) images of sample carbon-based nanomaterial composition S1.

[0251] Without being bound to any particular theory, it will be appreciated that the pores and holes seen in the SEM images suggest that the sample carbon-based nanomaterial composition S1 material has great potential for energy storage, as there is room for ion storage and transport. ID / IG less than 1 correlates with nanomaterials currently known in the research community. Multiple layers of fluffy powder-like material could also enable excellent mechanical structural applications, such as strengthening coatings or strengthening concrete. The edges seen in the TEM images and the D peak in Raman spectroscopy may reinforce this argument for mechanical strengthening. The high 2D peak (the peak at the far right of the Raman graph) suggests significant order at the molecular level of the sample.
