    • The object is to produce an aromatic compound (particularly, benzene) from a lower hydrocarbon having 2 or more carbon atoms (particularly, an ethane-containing gas composition such as ethane gas or natural gas) in the presence of a catalyst in a stable manner. Thus, disclosed is a process for production of an aromatic compound comprising the step of reacting ethane or an ethane-containing raw gas in the presence of a catalyst. The catalyst may comprise molybdenum supported on a metallosilicate such as H-type ZSM-5H or H-type MCM-22. In the reaction, the reaction temperature may fall within the range from 550°C to 750°C exclusive, preferably within the range from 600°C to 680°C inclusive, and the raw gas may additionally contain methane or hydrogen, thereby improving the production efficiency or stability.
    • 本发明的目的是在催化剂的存在下以稳定的方式从具有2个或更多个碳原子的低级烃(特别是含乙烷气体组合物,例如乙烷气体或天然气)中产生芳族化合物(特别是苯) 。 因此,公开了一种生产芳族化合物的方法,包括在催化剂存在下使乙烷或含乙烷的原料气体反应的步骤。 催化剂可以包含负载在金属硅酸盐上的钼,例如H型ZSM-5H或H型MCM-22。 在反应中,反应温度可以在550℃至750℃的范围内,优选在600℃至680℃的范围内,原料气体可另外含有甲烷或氢气,从而改善 生产效率或稳定性。
