    • This invention is for a catalyst for conversion of a hydrocarbonaceous feed. The catalyst is a zeolite aluminosilicate with a silicon to aluminum molar ratio from about 70: 1 to about 100: 1 on which a noble metal has been deposited. The zeolite catalyst may contain other optional tetravalent and trivalent elements in the zeolite framework. The zeolite structure may be MFI, FAU, TON, MFL, VPI, MEL, AEL, AFI, MWW or MOR. The catalyst is synthesized by preparing a zeolite containing aluminum, silicon and, optionally, other elements, such as germanium, in the framework, depositing a noble metal, such as platinum, on the zeolite and calcining the zeolite. The catalyst may be used for aromatization of alkanes to aromatics. One embodiment is a MFI zeolite catalyst which may be used for the aromatization of alkanes having two to six carbon atoms per molecule to aromatics, such as benzene, toluene and xylenes.
    • 本发明是用于烃类进料转化的催化剂。 该催化剂是一种硅铝酸盐沸石,其硅与铝的摩尔比为约70:1至约100:1,其上沉积有贵金属。 沸石催化剂可以在沸石骨架中含有其它任选的四价和三价元素。 沸石结构可以是MFI,FAU,TON,MFL,VPI,MEL,AEL,AFI,MWW或MOR。 通过在骨架中制备含有铝,硅和任选的其它元素如锗的沸石来合成催化剂,在沸石上沉积贵金属如铂,并煅烧沸石。 催化剂可用于将烷烃芳构化成芳族化合物。 一个实施方案是MFI沸石催化剂,其可用于每分子具有2-6个碳原子的芳族化合物与芳族化合物如苯,甲苯和二甲苯的芳族化。
