example 1
[0151] Referring to Figure 3, pyrolysis of methane is performed to form hydrogen and solid carbon, which are separated by filtration in a bubble lift pump. 100% methane was used as feed 101 into a reactor containing a molten mixture of 50% KCl and 50% NaCl salts at a rate of 30 sccm at 1000° C. through a concentric inlet pipe 202 made of quartz. Feed gas is caused to bubble upward in liquid filled reactor 332 . The methane reacts within the bubbles, and the products carbon and hydrogen, as well as the liquid, rise up the reactor due to their density differences. At the top of the liquid, channels allow the carbon and gas containing liquid to move out of the main reactor section 335 and through the filter 336 where the solid carbon is retained and the molten salt is passed. The filter is removable and the photo shows the solid carbon remaining on the filter. The gas phase product is primarily hydrogen leaving reactor 337. The molten salt returns to the bottom of the reactor ...

[0153] (Pyrolysis of Methane in Binary Molten Salts)
[0154] In the second example, according to the simplified diagram Figure 15 , methane is thermally decomposed in the reactor configuration. Some embodiments may also contain more reaction zones, post-reaction separation units or gas preheating units.
[0155] In this particular example, at a pressure of 1 bar, a methane feed stream 1501 at a flow rate of 15 sccm was bubbled through a quartz inlet tube 1502 (3 mm outer diameter (OD) and 2 mm inner diameter (ID)) into a In the alkali metal halide molten salt 1503 in the reactor 1504 (OD is 25 mm, ID is 22 mm). will total 77cm 3 The molten salt is loaded in the reactor. The bubble ascent velocity was estimated to be 24 cm / sec, resulting in a gas residence time of approximately 0.75 sec. Collect gaseous products such as hydrogen, C from the top 1505 of the column 2 Hydrocarbons (such as ethane, ethylene, and acetylene), aromatic hydrocarbons (such as benzene), and unrea...

[0162] (MP in carbon-salt slurry)
[0163] In this example, according to the simplified illustration Figure 15 , methane is thermally decomposed in the reactor configuration. Some embodiments may also contain more reaction zones, post-reaction separation units or gas preheating units. Other embodiments may incorporate solids suspended in molten salt media to increase reaction rates and increase reactive surface area. For example, both metal and carbon-based materials have been thoroughly explored as heterogeneous methane conversion catalysts.
[0164] In this particular example, a feed stream 1501 of methane (15 sccm) was bubbled through a quartz inlet tube 1502 (OD 3 mm and ID 2 mm) at 1000° C. at a pressure of 1 bar into a quartz reactor housed in (OD is 25mm, and ID is 22mm) in alkali metal halide molten salt 1503 (ie NaCl, NaBr, KCl or KBr). will total 77cm 3 The molten salt is loaded in the reactor. The bubble ascent velocity was estimated to be 24 cm / sec, resultin...
