    摘要： This invention relates to a process for the aromatization of C6 to C12 alkanes, such as hexane, heptane and octane, to aromatics, such as benzene, ethyl benzene, toluene and xylenes, with a germanium-containing zeolite catalyst. The catalyst is a non-acidic aluminum-silicon-germanium zeolite on which a noble metal, such as platinum, has been deposited. The zeolite structure may be of MFI, BEA, MOR, LTL or MTT. The zeolite is made non-acidic by being base-exchanged with an alkali metal or alkaline earth metal, such as cesium, potassium, sodium, rubidium, barium, calcium, magnesium and mixtures thereof, to reduce acidity. The catalyst is sulfur tolerant and may be pretreated with a sulfur compound, i.e., sulfided. The hydrocarbon feed may contain sulfur up to 1000 ppm. The present invention could be applicable to a feedstream which is predominantly paraffinic and/or low in naphthenes. Lowering the hydrogen to hydrocarbon ratio increases conversion and aromatics selectivity.

    摘要翻译： 本发明涉及一种使用含锗沸石催化剂将C6至C12烷烃如己烷，庚烷和辛烷芳构化成芳族化合物如苯，乙苯，甲苯和二甲苯的方法。 催化剂是沉积贵金属如铂的非酸性铝硅锗沸石。 沸石结构可以是MFI，BEA，MOR，LTL或MTT。 沸石通过与碱金属或碱土金属如铯，钾，钠，铷，钡，钙，镁及其混合物进行碱交换而制成非酸性，以降低酸度。 催化剂是耐硫的，并且可以用硫化合物预处理，即硫化。 烃进料可含有高达1000ppm的硫。 本发明可以应用于主要是石蜡和/或低环烷烃的进料流。 降低氢气与烃的比例会提高转化率和芳烃选择性。

    摘要： This invention is for a catalyst for conversion of alkanes having two to six carbon atoms per molecule to aromatics. The catalyst is a MFI zeolite with a crystallite size of less than 15 microns with, in addition to silicon and aluminum, germanium as a framework element. Platinum is deposited on the zeolite. The zeolite may contain other optional tetravalent and trivalent elements in the zeolite framework. The catalyst is synthesized by preparing a zeolite containing aluminum, silicon, germanium and, optionally, other elements in the framework, calcining the zeolite and depositing platinum on the zeolite. The catalyst may be used for aromatization of alkanes, such as propane, to aromatics, such as benzene, toluene and xylenes.
