    • Disclosed is a zeolite-containing molded catalyst for use in the production of an aromatic hydrocarbon compound from a light hydrocarbon raw material by catalytic cyclization, wherein the catalyst is reduced in both of the deterioration caused by the deposition of coke during the reaction and the permanent deterioration induced by the contact with high-temperature steam during the catalyst reproduction process and can produce a product for a prolonged period with high yield in a stable manner. In the zeolite-containing molded catalyst, the zeolite contained therein satisfies the following requirements (1), (2) and (3): (1) the zeolite is a medium pore zeolite having a pore size of 5 to 6.5 u; (2) the zeolite has a primary particle diameter of 0.02 to 0.25 mum; and (3) the zeolite contains at least one metal element selected from the group consisting of metal elements belonging to Group IB on the periodic table. The catalyst contains at least one element selected from the group consisting of elements belonging to Groups IB, IIB, IIIB and VIII on the periodic table.
    • 公开了一种用于通过催化环化从轻烃原料生产芳族烃化合物的含沸石的模制催化剂,其中催化剂在反应期间由焦炭沉积引起的劣化和永久性 在催化剂再生过程中与高温蒸汽接触引起的劣化,并且可以以稳定的方式以高产率长时间地生产产品。 在含沸石的成型催化剂中,其中所含的沸石满足以下要求(1),(2)和(3):(1)沸石是孔径为5〜6.5μm的中孔沸石; (2)沸石的一次粒径为0.02〜0.25μm; 和(3)沸石含有选自元素周期表中属于IB族的金属元素的至少一种金属元素。 该催化剂含有选自元素周期表中属于IB,IIB,IIIB和VIII族的元素中的至少一种元素。
