    • The present invention relates to a process for the non-oxidative dehydroaromatization of a feed stream containing C1-C4 aliphatics comprising the steps I, feeding the feed stream E into a reaction zone 1, reacting the feed stream E under non-oxidative conditions in the presence of a particulate catalyst to give a product stream P containing aromatic hydrocarbons, and removing the product stream P from the reaction zone 1; II, transferring the catalyst that is reduced in its activity by deposited coke into a reaction zone 2; III, at least partial regeneration of the catalyst with feed of a hydrogen-containing gas stream H in a reaction zone 2, wherein at least some of the deposited coke is converted into methane and a methane-containing gas stream M is formed that is fed at least in part to the reaction zone 1; IV, removing the catalyst from the reaction zone 2 and V, recirculating at least some of the catalyst that is removed to the reaction zone 1, wherein reaction zone 1 and reaction zone 2 are arranged spatially adjacently in the same reactor.
    • 本发明涉及一种用于含有包含I的步骤供给反应物料流E加入反应区1,非氧化条件下的反应物料流E在颗粒状催化剂存在下反应以形成芳族进料流中的C1-C4脂族化合物的非氧化性脱氢芳构化的方法 产物料流P和执行从反应区P 1,II。通过在其活性催化剂在反应区2,III传送沉积的焦炭损害了产品流含烃。 至少部分地再生催化剂,形成由在反应区2供给氢-H含有其中至少所述沉积的焦炭的一部分被转化为甲烷和含甲烷的气体流M中的气体流,其被至少部分地输送到反应区1,IV。运行催化剂 从反应区2和V.回收至少在反应区1中进行,所述催化剂的一部分,其中,所述反应区1和反应区2相邻设置空间,以在同一反应器彼此连接。
