Methane was converted to light olefins (ethene and propene) or higher hydrocarbons in a continuous flow reactor below 375 °C over H-SAPO-34 catalyst via an in situ halogenation (chlorination/bromination) protocol. The reaction conditions can be efficiently tuned toward selective monohalogenation of methane to methyl halides or their in situ oligomerization to higher hydrocarbons. The presence of C5+ hydrocarbons in the reaction products clearly indicates that by using a properly engineered catalyst under optimized reaction conditions, hydrocarbons in the gasoline range can be produced. This approach has significant potential for feasible application in natural gas refining to gasoline and materials under moderate operational conditions.
甲烷在 375°C 以下通过原位卤化（氯化/溴化）方案在 H-SAPO-34 催化剂上于连续流反应器中转化为轻烯烃（乙烯和丙烯）或更高碳氢化合物。通过该反应条件可有效地调变至甲烷的单卤化反应以生成卤代甲烷或其原位齐聚以生成更高碳氢化合物。反应产物中存在 C5+烃类清楚地表明，通过在优化的反应条件下使用适当设计的催化剂，可以生产出汽油范围内的烃类。在温和的操作条件下，该方法在天然气精制为汽油和材料方面具有很大的潜在可行应用。
