Embodiment 1

[0035] Embodiment 1: as figure 1 As shown, a promotion device for methane conversion mainly includes a raw material tank 1, a preheating device 2, a homogenization buffer tank 3, an activation promotion device 4, a conversion reaction chamber 5 and a liquefaction collection device 6,

[0036]The raw material tank 1 includes a methane tank 11 and an oxygen tank 12. The outlet of the methane tank 11 is provided with an electric control valve one 111, and the outlet of the oxygen tank 12 is provided with an electric control valve two 121, an electric control valve one 111, and an electric control valve two. 121 are respectively controlled by the connected gas flow controller 13, and are used to control the gas output rate of methane and oxygen according to the set ratio,

[0037] The preheating device 2 includes a methane preheating pipe 21 communicated with the electric control valve one 111 and an oxygen preheating pipe 22 connected with the electric control valve two 121. Both...

Embodiment 2

[0043] Embodiment 2: utilize the promoting device that embodiment 1 provides to carry out the promoting method of methane conversion, mainly comprise the following steps:

[0044] S1: preheating treatment

[0045] Input methane and oxygen into the gas flow controller 13 according to the reaction ratio, and the gas flow controller 13 controls the outlet flow of the methane tank 11 and the oxygen tank 12 respectively, so that methane and oxygen enter the methane preheating pipe 21 and the oxygen preheating pipe respectively. In 22, the circulation pump 24 circulates the heat transfer liquid heated by the mechanism heater 26 in the heating pipe 23, preheats the methane and oxygen in the methane preheating pipe 21 and the oxygen preheating pipe 22, and enters the methane preheating pipe 21, The heat transfer liquid flow ratio in the oxygen preheating pipe 22 is controlled by the diverter valve 25, so that the methane and oxygen in the methane preheating pipe 21 and the oxygen preh...

experiment example

[0052] Experimental example: research example 1 provides the influence of promoting device on methane conversion efficiency

[0053] Experimental conditions: The conversion promotion device provided in Example 1 and the existing industrial-grade methane conversion device A were respectively used to convert the same volume of methane gas, and the volumes of the converted synthetic gas were detected for comparison. The comparison results are shown in Table 1. :

[0054] Table 1 Comparison table of methane conversion efficiency

[0055]

[0056] Conclusion: When the conversion promotion device provided in Example 1 converts the same volume of methane gas, the volume of oxygen consumed is small, the conversion cost is low, and the volume of synthesis gas generated is large, and the conversion rate is higher.

Description

technical field [0001] The invention belongs to the technical field of energy conversion, and in particular relates to a promotion device for methane conversion and a promotion method thereof. Background technique [0002] There are abundant natural gas resources in nature. As a chemical raw material, natural gas is mainly used to synthesize ammonia, methanol and its derivatives, and its consumption only accounts for 5%-7% of natural gas consumption. It can be seen that as a chemical raw material, it cannot be compared with petroleum. However, since natural gas reserves far exceed oil reserves, in the long run, with the reduction of oil resources and the increasing difficulty of exploitation, the decline of the relative price of natural gas to oil and the advancement of natural gas chemical technology, natural gas may replace oil in the 21st century. Main energy and chemical raw materials. Methane is the main component of natural gas, research and development of methane u...
