    • There is provided a zeolite-containing molded catalyst for use in production of aromatic hydrocarbon compounds by catalytic cyclization from light hydrocarbon feedstock, whereby deterioration due to precipitation of carbonaceous material during the reaction and permanent degradation due to contact with high-temperature steam during the catalyst regeneration process are suppressed to thereby allow stable production with high yield over a long period of time. In this catalyst, the zeolite contained in the zeolite-containing molded catalyst fulfills the following conditions (1), (2) and (3): (1) the zeolite is a medium pore diameter zeolite with a pore diameter of from 5 to 6.5 Å; (2) the zeolite has a primary particle diameter in a range of from 0.02 to 0.25 μm; and (3) the zeolite contains at least one metal element selected from the group consisting of the metal elements belonging to Group IB in the periodic table, and the zeolite-containing molded catalyst also contains at least one element selected from the group consisting of the elements belonging to Groups IB, IIB, IIIB and VIII in the periodic table.
    • 提供了一种通过轻烃原料催化环化生产芳族烃化合物的含沸石成型催化剂,由于在反应过程中碳质材料的沉淀而劣化,并且由于在催化剂中与高温蒸汽接触而导致永久性降解 再生处理被抑制,能够长期稳定地以高收率生产。 在该催化剂中,含沸石的成型催化剂中所含的沸石满足以下条件(1),(2)和(3):(1)沸石是孔径为5〜6.5的中孔径沸石 一个; (2)沸石的初级粒径在0.02〜0.25μm的范围内; 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,并且含沸石的成型催化剂还含有选自以下的至少一种元素: 属于元素周期表IB,IIB,IIIB和VIII族的元素。
