(Summary description)Low carbon alkanes (C1~C4) are very rich carbon hydrocarbon resources, widely exist in natural gas, oilfield gas, coalbed methane and catalytic cracking gas. With the depletion of petroleum resources in the world, it is particularly important to prepare high value-added chemical raw materials from natural gas, oilfield gas and coalbed methane. Due to low carbon alkane chemical inertness is stronger, in the early days of the low carbon alkane in olefins reaction adopts highly active oxidant O2 and N2O (such as 1982 Keller precursors of sex work oxidative coupling of methane to olefin response), these highly reactive oxidants in relatively high low carbon alkane conversion rate at the same time, also caused the product further oxidation, so difficult to achieve the desired purpose product selectivity. Since the 1990s, people began to explore plasma activation method and plasma-catalyzed co-activation method to carry out the conversion reaction of low carbon alkanes.   Methane conversion reaction in low-temperature plasma at atmospheric pressure:   Methane (CH4) is the main component of natural gas, accounting for more than 90% of total natural gas. Natural gas reserves are very rich. In 2015, the world's proven natural gas reserves were 1.97x10^21m3, and the recoverable natural gas reserves in China were 4.94x10^18m3. Broken less in recent years, with the oil resource, natural gas, for a total of considerable reserves become the 21st century is one of the promising substitute energy and chemical raw materials but at the moment, the effective utilization of natural gas is still quite low, the main reason is that the main components of the gas methane is very stable organic small molecule structure, four C - H average keys for 414 kj/mol, CH3 - H key in the key for 435 kj/mol, difficult to activate. How to convert methane into liquid fuel easily transported and chemical products with high added value is one of the research hotspots.
