(Summary description)Chengfeng Zhizao Plasma introduces the importance of ethylene as a chemical raw material for industrial development: The mixed gas of methane and ethane widely exists in natural gas, oilfield gas, refinery gas and catalytic cracking gas, and the relative content of ethane is small. Separating and purifying methane and ethane and then utilizing them separately is costly. Without separation, directly using methane containing part of ethane as raw material to carry out the conversion reaction is a practical need from many occasions. The proven oil reserves in my country are 2.27×1017t and the natural gas reserves are 1.97×1021 m3. With the continuous development and utilization of the above resources, the amount of ethane in natural gas, oilfield gas, refinery gas and catalytic cracking gas will increase sharply. . Therefore, it is necessary to carry out the research on the ethane conversion reaction, which is of great significance for the rational utilization of ethane. As an important organic chemical raw material, ethylene is one of the symbols to measure the development level of a country's chemical industry. As we all know, the production of ethylene from ethane has always been one of the main processes of petrochemical industry. The traditional method is high-temperature cracking and dehydrogenation, which is a strong endothermic process. It not only requires high temperature (generally higher than 850 °C), but also needs to be carried out under negative pressure (adding a large amount of superheated steam for dilution), which consumes a lot of energy. , the operation is complicated, and the product separation is very difficult. If catalytic dehydrogenation is used, the reaction temperature can be lower than that of pyrolysis dehydrogenation, but it still has its limitations and is not sufficiently competitive. Moreover, with the continuous depletion of petroleum resources, the potential for preparing raw material ethylene from petroleum is nearly exhausted, and it is difficult to compete with petrochemicals economically from coal, and the oxidative dehydrogenation of gaseous alkanes is a realistic and effective way to fill this gap. way. Under the situation of increasingly tight energy supply, further efficient utilization of gaseous carbon resources has important strategic significance.
