    • A catalyst, a process for making the catalyst and a process for using the catalyst in aromatization of alkanes to aromatics, specifically, aromatization of alkanes having two to six carbon atoms per molecule, such as propane, to aromatics, such as benzene, toluene and xylene. The catalyst is an aluminum-silicon-germanium zeolite on which platinum has been deposited. Germanium is in the framework of the crystalline zeolite. Platinum is deposited on the zeolite. The catalyst may be supported on magnesia, alumina, titania, zirconia, thoria, silica, boria or mixtures thereof. The catalyst may contain a sulfur compound on the surface of the catalyst. The sulfur compound may be added to the catalyst in a pretreatment process or introduced with the hydrocarbon feed to contact the catalyst during the aromatization process. Generally, the catalyst may be of the formula M[(SiO2)(XO2)x(YO2)y]Z+y/n where M is a noble metal such as platinum or gold, X is titanium, germanium, tin or another tetravalent element, Y is boron, aluminum, gallium, indium, tellurium or another trivalent element, Z is a cation with a valence of n such as H+, Na+, K+, Rb+, Cs+, Ca2+, Mg2+, Sr2+or Ba2+, x varies from 0-0.15 and y is 0-0.125. An example catalyst would be represented as |H+Pt|[Si91Ge4Al1O192]-MFI.
    • 催化剂,制备催化剂的方法和使用该催化剂将烷烃芳构化成芳族化合物的方法,具体地说,将每分子如丙烷具有2-6个碳原子的烷烃芳构化成芳族化合物如苯,甲苯和 二甲苯。 催化剂是其上沉积有铂的铝 - 硅 - 锗沸石。 锗在结晶沸石的框架内。 铂沉积在沸石上。 催化剂可以负载在氧化镁,氧化铝,二氧化钛,氧化锆,氧化钍,二氧化硅,氧化硼或其混合物上。 催化剂可以在催化剂的表面上含有硫化合物。 可以在预处理过程中将硫化合物加入到催化剂中,或者在芳烃化过程中与烃进料一起引入以与催化剂接触。 通常,催化剂可以具有式M [(SiO 2/2)(XO 2 2)x X(Y 2/2) 其中M是贵金属如铂或金,X是钛,锗,锡或其中的一种或多种。 另一个四价元素,Y是硼,铝,镓,铟,碲或另外的三价元素,Z是n价的阳离子,例如H +,H + ,K + +, - + - , - - - - - - - - - - - - SUP>,Sr 2+或Ba 2+ 2,x从0-0.15变化,y是0-0.125。 示例性催化剂将被表示为| H + Pt | [Si 91 N 4 O 1 > 192 ] - MFI。
